Metal-Boride Catalysts for Indirect Liquefaction. Quarterly Technical Progress Report, December 1, 1982-February 28, 1983

摘要

Four iron-boride catalysts were prepared. Washing with methanol did not change the iron phase composition as did water. Potassium borohydride reduction produces essentially the same iron phases as sodium borohydride reduction. Solution phase reductions with NH sub 3 BH sub 3 were not productive. Reduction of ferric citrate with sodium borohydride produced a highly magnetic Fe sub 2 B which was easily washed. Reduction of cobalt boride catalysts at a low temperature resulted in a catalyst with unusual selectivities in CO hydrogenation, i.e. the product contained more than 95% C sub 5 -C sub 16 hydrocarbons. However, this catalyst deactivated rapidly. (ERA citation 08:025825)
