Claim 1
Independent Claim
130 words
A CATALYST SUPPORTED ON A POROUS CARRIER AND HAVING HIGH ACTIVITY FOR HYDRODESULFURIZATION OF SULFUR-CONTAINING HYDROCARBONS, SAID CATALYST CONTAINING ACTIVE HYDROGENATING COMPONENTS WHICH CONSIST ESSENTIALLY OF MOLYBDENUM AND AT LEAST TWO MEMBERS OF THE IRON GROUP METALS, THE IRON GROUP COMPONENTSBEING PRESENT IN SUCH AMOUNTS THAT THE SUM OF THE ATOMIC RATIOS OF THE IRON GROUP METALS TO MOLYBDENUM IS LESS THAN ABOUT 0.8 AND THE ATOMIC RATIO OF EACH IRON GROUP METAL TO MOLYBDENUM IS LESS THAN ABOUT 0.4., SAID ACTIVE HYDROGENATING COMPONENTS BEING PRESENT IN THE FORM OF A MEMBER OF THE GROUP CONSISTING OF OXIDES OF SAID METALS, SULFIDES OF SAID METALS, COMBINATIONS OF THE OXIDES OF THE IRON GROUP METALS WITH MOLYBDENUM OXIDE AND COMBINATIONS OF THE SULFIDES OF THE RION GROUP METALS WITH MOLYBDENUM SULFIDE.
