Effect of Catalyst Temperature Zoning on Upgrading a Coal-derived Liquid
Abstract
The objective of this study was to investigate the advantages and disadvantages of hydrotreating coal-derived liquids by temperature zoning. Hydrotreating was carried out in a two-stage trickle-bed reactor, varying the top zone temperature between 400�C (752�F) and 500�C (932�F) while maintaining the lower zone temperature at 400�C (752�F). Reactor plugging became excessive when the top zone temperature was operated above 450�C (842�F).
