Zinc chloride catalyst recovery for a coal hydrogenation process

Year: 1976

Type: report

Abstract: Recovery of a zinc chloride catalyst was investigated for the University of Utah's coal liquefaction process which occurs at 950/sup 0/F and 2000 psig in a coiled tubular reactor. The catalyst is recovered from the liquid oil product by water washing and from the coal char by ashing followed by acid leaching. Preliminary design of the catalyst recovery section for a 25,000 ton/day coal liquefaction plant with 99 percent recovery was completed. The total recovery cost was $12.07 and $8.97 per ton of coal for recovery processes with cross flow and countercurrent flow oil washing, respectively.
