According to an exemplary embodiment, a bubble column-type slurry bed Fischer-Tropsch synthesis reaction process can be provided, in which synthesis gas supplied continuously from the bottom of a reactor contacts suspended catalyst particles to form liquid hydrocarbons, gaseous hydrocarbons and water. Additionally, a slurry of suspended liquid products and catalyst particles can move from the reactor to the lower portion of a separation vessel to separate the catalyst particles and gaseous products. Further, a process can be provided in which the liquid products formed are sent to the separation vessel a process in which liquid products can be derived. Additionally, a process can be provided in which a slurry in which catalyst particles are concentrated is derived from the bottom of the separation vessel and circulated to the bottom of the reactor, are driven by the driving force of synthesis gas without using an external drive power source.

Bubble column-type Fischer-Tropsch synthesis slurry bed reaction system

A porous preform (carrier) is soaked in an impregnating solution, which contains both of a catalytic-activity constituent, e.g. Ni and/or Co, and a carrier-forming constituent, e.g. Mg, Al, Zr, Ti and/or Ca, so as to simultaneously infiltrate the catalytic-activity and carrier-forming constituents into the porous preform. The impregnated preform is dried, calcined at a temperature of 700&#xb0; C. or higher and then activated at a temperature of 500&#xb0; C. or higher, whereby fine catalytic-activity particles are distributed on a surface of the porous carrier with high dispersion. Due to finely-distributed catalytic-activity particles, the surface of the catalyst is prevented from deposition of carbonaceous matters during reformation of hydrocarbon and held in an active state over a long term.

Hydrocarbon-reforming catalyst and a method of manufacturing thereof

Synthesis gas for FT synthesis is produced using a producing apparatus including an active carbon adsorbing vessel for adsorbing impurities in a natural gas, a hydro-desulfurizer for hydrogenating and desulfurizing sulfur content in the natural gas under a condition of a partial pressure of hydrogen of 100 to 200 kPa, a second hydrogen supplying line for supplying hydrogen to the natural gas between the hydro-desulfurizer and a reactor, the reactor for obtaining synthesis gas by reacting the natural gas, carbon dioxide and steam in the presence of a catalyst for reforming, and a heat recovering boiler for cooling the synthesis gas at a cooling rate of 2000 to 4000&#xb0; C./second.
