The objective of this research is to investigate and develop novel catalysts for the conversion of coal-derived synthesis gas into C/sub 1/-C/sub 4/ alcohols by a highly selective process. Variations of catalyst activity and selectivity for the synthesis of alcohols from H/sub 2//CO less than or equal to1 synthesis gas for a series of A/TX/sub 2/ 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 MoS/sub 2/, TaS/sub 2/, RuS/sub 2/, 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 TaS/sub 2/ was tested with H/sub 2//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 K/sub 2/CO/sub 3/ and TaS/sub 2/ to yield a 16.6 wt% K/sub 2/CO/sub 3//TaS/sub 2/ catalyst, (2) impregnation of TaS/sub 2/ under nitrogen with aqueous CsOOCH to yield a 0.15 wt% CsOOCH/TaS/sub 2/catalyst, and (3) impregnation if MoS/sub 2/ under nitrogen with CsOOCH to produce a 20.0 wt% CsOOCH/MoS/sub 2/ catalyst. 1 fig., 2 tabs.
