CATALYST CONSISTING OF INORGANIC CARRIER, PHOSPHORUS AND BORON AND ITS PRODUCTION AND USE THEREOF IN HYDROREFINING OF PETROLEUM FRACTION

摘要

PURPOSE: To enhance the hydrogenatioin activity of arom. hydrocarbon by forming a catalyst deposited with group VIB and group VIII of element periodic table or their compds. together with boron and a specific amt. of phosphorus on an inorg. carrier. CONSTITUTION: A porous inorg. matrix is impregnated by an aq. soln. compounded with a soluble compd. of at least one phosphorus, at least one soluble compd. of at least one metal of the group VIB of element periodic table and at least one soluble compd. of at least one metal of the group VIII of element periodic table. Next, this impregnated porous inorg. matrix is matured in a steam satd. atmosphere and is then dried and fired in air. The fired matter is thereafter impregnated by the soln. of a boron compd. and is then matured in the satd. atmosphere of a solvent. Further, the solvent is removed and baked in the air, by which the hydrorefining catalyst is obtd.
