(HC)3 Hydrocracking Technology

SPE International Thermal Operations and Heavy Oil Symposium, 2005
Abstract Refineries are processing bottoms and heavy oils to lighter products using either thermal cracking base technologies such as visbreaking, delayed and fluid coking, or solid catalyst base low to moderate hydroconversion technologies using fixed bed and ebullated bed reactors.

New developments in hydrocracking: low pressure high-conversion hydrocracking.

Catalysis Today, 1987
Abstract Hydrogen partial pressure is a key parameter for distillate hydrocracking processes. There are two types of distillate hydrocracking processes. Mild hydrocracking is an improved vacuum gas oil hydrotreatment process with a relatively low conversion, which operates at hydrogen pressures usually less than 50 bars.

Hydrocracking of diphenylmethane

Fuel, 1984
Abstract This study presents the role of H 2 S other than H-transfer catalyst in the hydrocracking of diphenylmethane with H 2 –H 2 S-pyrrhotite. The results indicate that the partial pressure of H 2 S controls the conversion of pyrrhotite to FeS and FeS 2 , which in turn is closely related to the promotional activity of pyrrhotite on the ...

HYDROCRACKER CREATION

Industrial Lubrication and Tribology, 1983
PROJECT Leader, Dr Geoff Dobson, in charge of Automotive Engine Lubricants at BP's Sunbury Research Centre, is the first to applaud his own good luck. It came as a blessed bonus to crown months of effort by him and his team to formulate a satisfactory mineral base oil which would allow BP to make continued headway into the light viscosity automotive ...

Hydrocracking: a review

Fuel, 1990
Abstract In this article the technology, kinetics, chemistry and reactor modelling of hydrocracking have been reviewed. While it is intended to provide a general overview of the recent advances in this process, greater emphasis has been given to technology and reactor modelling because of their industrial importance.

Hydrocracking distillate feedstocks

Chemistry and Technology of Fuels and Oils, 1986
The main shortcoming of single-stage hydrocracking is the very high level of feedstock cracking. The authors discuss the development of multistage technology in which each stage can operate under optimal conditions at a moderate conversion level, better flexibility in process control, and better process indexes.
