Title:
フィッシャー-トロプシュ合成を行うための触媒プラント及び方法
Document Type and Number:
Japanese Patent JP4913047
Kind Code:
B2
Abstract:
Fischer-Tropsch synthesis is performed on a CO/H*2 feed gas using a plurality of compact catalytic reactor modules ( 12 ) each defining catalytic reaction channels and coolant channels, in two successive stages, with the same number of reactor modules for each stage. The gas flow velocity in the first stage is sufficiently high that no more than 75% of the CO undergoes conversion. The gases are cooled ( 16 ) between successive stages so as to remove water vapour, and the pressure is reduced ( 20 ) before they are subjected to the second stage. In addition the reaction temperature for the second stage is lower than for the first stage, such that no more than 75% of the remaining carbon monoxide undergoes conversion during the second stage too. The deleterious effect of water vapour on the catalyst is hence suppressed, while the overall capacity of the plant ( 10 ) can be adjusted by closing off modules in each stage while keeping the numbers equal.
