Abstract
At least one decomposable molybdenum additive selected from the group consisting of a mixture of a molybdenum dithiophosphate and a molybdenum carboxylate and a mixture of a molybdenum dithiocarbamate and a molybdenum carboxylate is mixed with a hydrocarbon-containing feed stream. The hydrocarbon-containing feed stream containing such decomposable molybdenum additive is then contacted in a hydrovisbreaking process with hydrogen under suitable hydrovisbreaking conditions.
Claims22
A process for hydrovisbreaking a hydrocarbon-containing feed stream comprising the steps of:
- introducing a decomposable molybdenum additive selected from the group consisting of a mixture of a molybdenum dithiophosphate and a molybdenum carboxylate and a mixture of a molybdenum dithiocarbamate and a molybdenum carboxylate into said hydrocarbon-containing feed stream;
- and
- contacting said hydrocarbon-containing feed stream containing said decomposable molybdenum additive under hydrovisbreaking conditions with hydrogen, wherein said contacting is carried out in the absence of a solid support for said decomposable molybdenum additive.
