Extension of Residfining technology of hydroconversion

(1) Advances in Exxon proprietary RT family of catalysts have provided new processing options for increasing conversion with the commercially demonstrated Residfining technology. (2) Residfining processing extensions include a high temperature operation strategy. The high temperature operation allows extending 1050F/sup +/ conversion levels from 10-15 percent typically observed at low temperature start-of-run conditions to 45-50 percent with Arabian Light residuum. Coversion was further extended to levels in excess of 60 percent with a promising reactor system in combination with the proprietary catalysts. Product qualities were quite good for the various liquid product fractions requiring minmum downstream upgrading. 10 refs.
