What is Regeneration of Spent ZnCl Catalyst about?
The document summarizes research on regenerating spent zinc chloride catalyst from direct hydrocracking of coal. Spent catalyst from hydrocracking Colstrip subbituminous coal was used as feedstock. In a fluidized bed reactor, impurities in the spent catalyst like sulfur, nitrogen and carbon were burned off while zinc oxide was converted back to zinc chloride using hydrogen chloride gas. This primary regeneration step recovered most of the zinc, while coal ash and residual zinc were collected. A secondary re
