Abstract: The present invention relates to a process of preparing of a phosphorus-containing phosphorus-alumina support by a sol-gel method and a cobalt/phosphorus-alumina catalyst where cobalt is supported onto the phosphorus-alumina support as an active ingredient. The phosphorus-alumina support is prepared by a sol-gel method and has wide specific surface area with bimodal pore size distribution and high cobalt dispersion, thereby enabling to increase heat and mass transfer, stabilize the structure by modifying the surface property of alumina and decrease the deactivation rate due to the reduced oxidation of cobalt component during the F-T reaction. When Fischer-Tropsch reaction (F-T) is conducted on the catalyst, the catalyst maintains a superior thermal stability, inhibits the deactivation due to water generation during the F-T reaction and also causes relatively high conversion of carbon monoxide and stable selectivity of liquid hydrocarbons.

Abstract: The present invention relates to a continuous separation and discharge apparatus and method of solid catalysts and liquid products for Fischer-Tropsch synthesis reactions, and more particularly, to a continuous separation and discharge apparatus and method of solid catalysts and products for Fischer-Tropsch synthesis reactions involving the conversion of synthetic gas into synthetic oil, by which products of the Fischer-Tropsch synthesis including wax, as a long-chain hydrocarbon, can be stably obtained by continuously separating the products from a slurry comprising solid catalyst particles and the products using periodic pulses of a feeding gas and discharging the products through a lower portion of a reactor.

Abstract: The present invention relates to a method for preparing liquid hydrocarbons via a slurry phase Fischer-Tropsch (F-T) synthesis. In particular, the present invention relates to a method for preparing liquid hydrocarbons from syngas via slurry phase F-T synthesis using a catalyst, which can prevent the decrease in catalyst activity and filter clogging due to catalyst aggregation, simultaneously with improving selectivity for C5 or higher hydrocarbons by using C7-C12 alcohols having a high boiling point as an additive for a slurry reaction solvent or recycling the same alcohol separated from by-products that are generated during the F-T reaction. Since the method of the present invention is more carbon-effective and shows improved long-term stability of a reactor, it can be effectively used in the preparation of liquid hydrocarbons.

Abstract: The present invention relates to a cobalt/phosphorus-alumina catalyst in which cobalt is supported as an active component on a phosphorus-alumina support wherein phosphorus is supported on alumina surface. With a bimodal pore structure of pores of relatively different pore sizes, the catalyst provides superior heat- and matter-transfer performance and excellent catalytic reactivity. Especially, when Fischer-Tropsch (F-T) reaction is performed using the catalyst, deactivation by the water produced during the F-T reaction is inhibited and, at the same time, the dispersion and reducing property of cobalt and other active component are improved. Therefore, the cobalt/phosphorus-alumina catalyst for F-T reaction in accordance with the present invention provides good carbon monoxide conversion and stable selectivity for liquid hydrocarbons.
