Abstract
There is herein described a Fischer-Tropsch reactor. More particularly, there is described a Fischer-Tropsch reactor that incorporates forced flow through a small pore, thick layer, monolith supported catalyst and high levels of heat transfer that is able to operate with high levels of catalyst effectiveness. The catalyst bed (103) is supported on a distinct porous structure (101) through which the syn-gas flow is forced and the catalyst layer has a thickness of more than 200 microns.
Claims3
A reactor for converting synthesis gas in a Fischer-Tropsch process using a supported catalyst to produce heavy paraffins, wherein the catalyst is supported on a distinct porous structure through which the synthesis flow is forced and the catalyst layer has a thickness of more than 200 microns, wherein the catalyst support forms a distinct single internal surface with a geometric surface area greater than a cylinder within which it can be inscribed;
- wherein the catalyst support forms a planar cavity and
- a. wherein the planar cavity has at least one nozzle inlet;
- b. wherein the planar cavity contains catalyst substantially covering at least one of the outer or inner surface forming the cavity;
- and
- c. wherein a heat transfer surface adjacent to the planar cavity is formed into a pressure vessel from the edge welding of plates, by brazing or by compression within a frame or diffusion bonding of a channelled structure.
A reactor for converting synthesis gas in a Fischer-Tropsch process using a supported catalyst to produce heavy paraffins wherein the catalyst is supported on a distinct porous structure through which the synthesis flow is forced and the catalyst layer has a thickness of more than 200 microns, the reactor comprising a heat transfer device, wherein the heat transfer is within a cylindrical catalyst support provided by a bayonet arrangement of heat transfer tubes;
- and wherein a continuous layer of less than 1 mm thick with a pore size of less than 1000 nm substantially free of cobalt is fixed to the catalyst support.
A reactor for converting synthesis gas in a Fischer-Tropsch process using a supported catalyst to produce heavy paraffins, wherein the catalyst is supported on a distinct porous structure through which the synthesis flow is forced and the catalyst layer has a thickness of more than 200 microns, wherein the catalyst and porous support is placed between heat transfer tubes of less than 60 mm diameter;
- and wherein a cobalt catalyst within the Fischer-Tropsch Reactor is supported by a porous ceramic structure which has a characteristic pore size greater than 500 nm.
