ACCELERATED CRACKING OF RESIDUAL OILS AND HYDROGEN DONATION UTILIZING AMMONIUM SULFIDE CATALYSTS

摘要

A method for accelerating the exchange of hydrogen between a hydrogen donor and a petroleum resid to be subjected to cracking, visbreaking, or coking comprising incorporating an aqueous solution of ammonium sulfide into the mixture of donor and resid and subjecting the mixture to a period of heat-soaking at an elevated temperature.
