ABSTRACT:

The objective of this research is to investigate and develop novel catalysts for the conversion of coal-derived synthesis gas into C1 -C4 alcohols by a highly selective process. Variations of catalyst activity and selectivity for the synthesis of alcohols from H2 /CO less than or equal to1 synthesis gas for a series of A/TX2 compounds, where A is a surface alkali dopant, T is a transition metal, and X is a S, Se, or Te, will be determined. The base materials obtained include MoS2 , TaS2 , RuS2, and MoRuS/sub x/. These materials have been characterized in terms of x-ray powder diffraction patterns and BET surface areas. Of these pure materials, a 0.50 g sample of TaS2 was tested with H2 /CO = 1.0 synthesis gas at 81.6 atm and at temperatures of 295, 310, and 325/degree/C. Alkali doping of some of these materials has been carried out, and these include (1) a mechanical mixture of K2 CO3 and TaS2 to yield a 16.6 wt% K2 CO3/TaS2 catalyst, (2) impregnation of TaS2 under nitrogen with aqueous CsOOCH to yield a 0.15 wt% CsOOCH/TaS2 catalyst, and (3) impregnation if MoS2 under nitrogen with CsOOCH to produce a 20.0 wt% CsOOCH/MoS2 catalyst. 1 fig., 2 tabs.
