<onlyinclude>'''Chromatography''' enables the separation, identification, and purification of the components in a mixture. The mixture is composed of a ''mobile phase'' (fluid or gas) and a ''stationary phase''. The stationary phase is either a solid phase or a layer of a liquid adsorbed on the surface a solid support. The separation is based on the differential partitioning between the mobile and the stationary phase. <ref>{{Cite journal|title=Separation Tecniques: CHROMATOGRAPHY|year=2016|author=Ozlem Coskun|journal=Northern Clinics of Istanbul|doi=10.14744/nci.2016.32757}}</ref> Chromatography may be preparative or analytical.

=== Chromatography methods ===
[[File:Chromatography.png|thumb|206x206px|Liquid chromatography]]
By altering the mobile phase, the stationary phase, and/or the factor determining speed of travel, a wide variety of chromatographic methods are available, each ideal for different mixtures. Some of the most common forms of chromatography are as follows.<ref name=":1" />
 
'''Techniques by physical state of the mobile phase'''
 
* Gas chromatography
** the mobile phase is gaseous
* Liquid chromatography
** the mobile phase is liquid
 
'''Techniques by chromatographic bed shape'''
 
* Thin-layer chromatography (TLC)
** stationary phase is a thin layer of solid material, usually silica-based, and the mobile phase is a liquid
* Column chromatography
** stationary phase is within a tube (e.g. packed column with silica, as the illustration above)
 
'''Techniques by separation mechanism'''
 
* Ion exchange chromatography
** separates the components of a mixture based on their charge
* Size-exclusion chromatography
** separates molecules according to their size (Smaller molecules enter pores of the media and, therefore, molecules are trapped and removed from the flow of the mobile phase)
 
==Products==
The products of a chromatography depend on which method is applied. When applying a gas chromatography the mobile phase is gaseous, while the stationary phase is solid or viscous liquid. The products here are then gases and the separated molecules are then either bound to the solid or liquid phase. When applying a liquid chromatography the mobile phase is liquid and the stationary phase is solid, leading to liquid and solid end products.

==Process and technologies==
The mixture is dissolved in a fluid (gas or solvent) called the ''mobile phase,'' which carries it through a system (a column, a capillary tube, a plate, or a sheet) on which a material called the ''stationary phase'' is fixed''.'' The different constituents of the mixture have different affinities for the stationary phase. The different molecules stay longer or shorter on the stationary phase, depending on their interactions with its surface sites. So, they travel at different apparent velocities in the mobile fluid, causing them to separate.  The separation is based on the differential partitioning between the mobile and the stationary phases. Subtle differences in a compound's partition coefficient result in differential retention on the stationary phase and thus affect the separation.

From pre-treatment of the vegetable oils and fats to the final polishing or post-treatment, Grace’s TRISYL<sup>®</sup> silica is proven technology that results in more process savings compared to clay or silicates. Our silica technology comprised of highly pure synthetic amorphous silica was developed for maximum adsorption and significantly reduces phospholipids, trace metals and animal proteins in both physical and chemical refining operations. Recommended for the pre-treatment of feedstock for both renewable diesel and first generation biodiesel, TRISYL<sup>®</sup> silica can also be used in biodiesel post-treatment by helping to substantially reduce the need for water washing. TRISYL<sup>®</sup> silica enables the economic conversion of biomass to biodiesel and renewable diesel to be more efficient and environmentally sustainable.
 
Renewable diesel – commonly referred to as green diesel or HVO (hydrotreated vegetable oil) – continues to grow in prevalence. Grace’s TRISYL<sup>®</sup> silica helps maximize service life of catalysts by consistently removing trace materials and impurities from difficult-to-refine feedback and helps achieve economies of scale in renewable diesel production. Unlike activated bleaching earth (ABE), TRISYL<sup>®</sup> silicas provide superior adsorption capacity for phospholipids and metals at all free fatty acid concentrations. This reduces costs on spent solids and disposal but also reduces oil lost during pre-treatment.

XPure is committed to improving separation efficiency by designing and delivering innovative, customized continuous ion exchange and chromatography systems. XPure uniquely features expanded bed adsorption technology that is integrated in our SMB configured systems. This enables us to directly process particulates containing feed streams, for example from fermentation or plant based juice streams.


''ABC was founded in 20... 12 by KNN and Syncom, in collaboration with the university of Groningen, Netherlands. The company is a technology provider developing chemical recycling technologies for different feedstocks including non-food bio- and plastics waste. In 2018 a pilot plant with the capability to process biomass and plastic waste was set up at the Zernike Advanced Processing (ZAP) Facility. The company is now focused on setting up their first commercial plant with a capacity of 20,000 to 30,000 tonnes. The investing phase B was recently completed, with the last investment phase in 2019 the financial requirements are fulfilled to complete the commercialisation activities to build the plant which is expected for 2023.''
XPure’s Simulated Moving Bed (SMB) technology overcomes the intermittent nature of classical chromatography by introducing more columns, thus allowing for simultaneous separation to occur. XPure’s patented technology for continuous chromatography and ion exchange enables the isolation of desired components from such complex mixtures while improving yield and purity at lower costs. Our systems integrate modular and scalable simulated moving bed hardware with a smart and flexible software platform, enabling the flexibility to implement a wide range of process control strategies. This holistic approach reduces resin and solvent consumption and increases product concentrations, purity, and yields. This singular focus on process technology and equipment means we are independent of resin and media suppliers. Rather, our team of experts deliver the suitable and cost-effective solutions to meet your separation requirements.


describe their technology, here is an example
XPure enables the purification of bio-based chemicals and mild fractionation of food components using an efficient technology that contributes to a sustainable process industry.


''The technology is based on an Integrated Cascading Catalytic Pyrolysis (ICCP) process, being able to produce aromatics including benzene, toluene, and xylene (BTX) as well as light olefins from low grade biomass and plastics waste. This technology utilises catalytic cracking in a two-step process at temperatures between 450- 850 °C. In the first step the feedstock material is vaporised via thermal cracking. The pyrolysis vapours are then directly passed into a second reactor in which they are converted into aromatics by utilising a zeolite catalyst which can be continuously regenerated. Finally, the products are separated from the gas via condensation. An ex situ approach of catalytic conversion has several advantages such as the protection of the catalyst from deactivation/degradation expanding its lifetime, a greater variety of feedstock, and a precise adjustment of process conditions (e.g. temperature, catalyst design, and Weight Hourly Space Velocity (WHSV) in each step for improved yields. In current pilot plant with 10 kg h-1 feed capacity for either waste plastics or biomass, final design details are established, which will be include in the running engineering activities for the commercial plant.''

Chromatography enables the separation, identification, and purification of the components in a mixture. The mixture is composed of a mobile phase (fluid or gas) and a stationary phase. The stationary phase is either a solid phase or a layer of a liquid adsorbed on the surface a solid support. The separation is based on the differential partitioning between the mobile and the stationary phase. [1] Chromatography may be preparative or analytical. The purpose of preparative chromatography is to separate the components of a mixture for later use, and is thus a form of purification. [2][3] Analytical chromatography is done normally with smaller amounts of material and is for establishing the presence or measuring the relative proportions of analytes in a mixture. The two are not mutually exclusive. [4]

Feedstock

Origin and composition

Through the different chromatography forms and methods (as can be seen below), the possible biomass feedstocks are versatile. Examples are:[5]

  • Wood chip
  • Residual bacterial biomass
  • Sewage sludge
  • Straw
  • Stalk
  • Algae biomass

Pre-treatment

As a purification and analytical process, possible pre-processes are for example[5][6][7]:

Process and technologies

To separate the components of a mixture, the mixture is dissolved in a substance, the mobile phase, which carries it through a second substance, the stationary phase. The different components of the mixture travel through the stationary phase at different speeds, causing them to separate from one another. [8] The different molecules stay longer or shorter on the stationary phase, depending on their interactions with its surface sites. The separation is based on the differential partitioning between the mobile and the stationary phases. Subtle differences in a compound's partition coefficient result in differential retention on the stationary phase and thus affect the separation. A schematic illustration of the process can be seen below (illustrates column chromatography).
