Abstract
Disclosed is a method for accelerating the exchange of hydrogen between a hydrogen donor and a petroleum resid to be subjected to cracking, visbreaking, or coking. Acceleration is effected by incorporating an aqueous solution of ammoniun sulfide into the mixture of donor and resid and subjecting the mixture to a period of heat-soaking at an elevated temperature.
