A commercial coal liquefaction catalyst, Amocat 1A, has been subjected to a deactivation study in a laboratory catalytic coal liquefaction microreactor. Carbonaceous and metal deposits were the two major factors causing catalyst deactivation. The carbonaceous material deposited primarily in the interior of the catalyst particle and clogged the pores in a uniform manner. The metals deposit was rich...
Experiments were conducted in an externally heated drop-tube furnace to assess the effectiveness of the chemical calcium magnesium acetate [CMA, CaMg 2 (CH 3 COO) 6 ] as a combustion catalyst and a coal pretreatment agent for reducing SO 2 emissions. Bituminous coal particles of two distinct sizes, pulverized (75-90 μm) or micronized and beneficiated (mean diameter...
