PRECURSOR FOR HYDROGENATION CATALYST

摘要

PURPOSE:To obtain a precursor for catalysts which is strong to poison and can avert coking by dipositing iron oxide on a titania carrier as a precursor for hydrogenation catalysts. CONSTITUTION:As a procursor for hydrogenation catalysts in the presence of hydrogen for heavy duty oil contg. polycyclic arom. compds. and ash content, iron oxide which is an activator is deposited on a titania carrier. The resultant precursor for catalysts is strong to ash content or poison such as halogen, is highly active at the temp. occuring on coking and is produced inexpensively.
