OVERVIEW OF HEAVY OIL IN-SITU HYDROGENATION

Abstract

Abstract: The principle of in-situ hydrogenation (or catalytic transfer hydrogenation)(CTH) was briefly introduced, the application of CTH in the field of heavy oil treatment was reviewed, especially in the application of hydrogen-supplying thermal cracking and hydrogen-supplying thermal cracking technology, and the application of related patents was analyzed. In addition, the influence of hydrogen-supplying agent and catalyst on the reaction was briefly described. In the future, the selection of suitable hydrogen donor, catalyst and process should be further optimized to form a heavy oil treatment process that could run for a long period, provide the new technical scheme for Chinese refining industry.

Key words: in-situ hydrogenation, catalytic transfer hydrogenation, hydrogen donor, heavy oil
