Problems solved by technology

CN1110304A has announced a kind of preparation method of the silicon-containing and phosphorus-containing aluminum oxide of macroporous, in the preparation process of this aluminum oxide, silicon and phosphorus are added with step-by-step colloidal method, and this method process is complicated, and production cost is high, And the amount of silicon added is limited, generally about 1wt% to 4wt%, which has a limited effect on the regulation of catalyst performance
CN1321726A introduces a kind of hydrogenation treatment catalyst and preparation method thereof, adds silica sol during the kneading process of aluminum hydroxide monohydrate (pseudo-thin water aluminum oxide), but because silica sol is the material with bigger micelle, it is not easy to disperse evenly, its not fully functioning

Abstract

A catalyst for petroleum fractions hydrogenation and its preparation are disclosed. It includes preparing silicon binder, fully mixing pseudooligaaqueous aluminum oxide, fluo-compound and compound containing VIB family metals such as molybdenum or tungsten with silicon binder, kneading, stripping, shaping, drying, and high temperature roasting to form Mo(W)/F-SiO2-Al2O3 as carrier, immersing in an aqueous phosphoric acid solution containing VIIIB family metals such as nickel or cobalt, drying and high temperature roasting to obtain the catalyst of petroleum fractions hydrogenation. Its advantages include simple preparation, easy operation, low cost, good active ingredient dispersing status, large specific area and pore volume.

Description

technical field [0001] The invention relates to a petroleum distillate hydrorefining catalyst and a preparation method thereof, in particular to a high metal content hydrorefining catalyst with large specific surface area and pore volume and a preparation method thereof. Background technique [0002] Petroleum fractions contain organic sulfur compounds, organic nitrogen compounds, and organic metal (such as nickel, vanadium, iron) compounds and other harmful compounds. The existence of these compounds not only affects the storage stability of oil products, but also emits harmful pollutants during use. Sulfur, nitrogen, and oxide gases will pollute the environment, and may also cause catalyst poisoning during the processing of some petroleum fractions. The main purpose of hydrofinishing is to remove these harmful compounds from petroleum fractions. Mo(W)-Ni(Co)-Al 2 o 3 Catalysts are widely used in the hydrorefining process of petroleum distillates. [0003] A hydrorefini...
