โœฆ Synopsis

It has been shown that the bacterium Thiobacillus ferrooxidans can solubilize MoS, from coal liquefaction catalyst residues. The MoS, is formed during the liquefaction process from a molybdenum catalyst precursor. MO& is insoluble; in order to be recovered and reused, it must be converted to a soluble form. T. ferrooxidans can oxidatively solubilize the molybdenum in MoS, to molybdate, in which form it can be recovered as a soluble or HCI extractable material. Bioleaching experiments show that with a starting cell concentration

A commercial coal liquefaction catalyst, Amocat lA, 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 inte
