Abstract
PURPOSE: To reduce byproduct methane and to increase the yield of olefins each having carbon atoms of >=5 by combining a cobalt Fischer-Tropsch catalyst with a carrier based on a zeolite molecular sieve. CONSTITUTION: The preparation of this catalyst combined with a molecular sieve carrier, comprises: treating an LZ-2/0 molecular sieve with steam to extract acid from the molecular sieve and to form a TC-123 molecular sieve carrier, wherein the LZ-2/0 molecular sieve is prepared by using a zeolite molecular sieve having an SiO2 /Al2 O3 ratio of >=8.0 as a starting material; and filling the pores of this carrier with a solution of ethylene glycol, water, an alcohol, or the like, which contains Co and an Mn promoter. At the time of performing synthesis gas conversion by using the cobalt Fischer-Tropsch catalyst thus prepared, the methane formation can be reduced and the C5 + yield can be improved.

+t-tg), cobalt catalysts have the advantage of higher activity and better selectivity to motor gasoline, but they inherently remove excess methane (an unwanted product). There are problems with the production and the paraffinic nature of the product. If stable cobalt F reduces methane formation, increases the yield of C5+ fractions (C5+) and shows an improved content of olefins, especially in the C5 or less (C5-) range, If a -T catalyst were found, it would be an important catalyst improvement.

It has been shown to be effective in shifting the product distribution towards heavier products, as also observed with the catalyst in the present invention. The work of Eidus and Bulanova showed a similar effect when adding ZrO□ to the same type of catalyst, but this was not the case for Applicants' Mn-promoted Co/TC-123 catalyst system. This was not observed with the addition of Z r Ot to . To the best of Applicants' knowledge, there are no studies reporting the use of catalysts promoted by combining Mn and Zr.
