Abstract

A protective agent for supporting and covering catalyst and protecting catalyst from being caked and poisoned contains A / O3, SiO2, Fe2O3, MoO, NiO, WO and CoO. The said protective agent is prepared from y-Al2O3, Kaolin, potash feldspar, waste catalyst, calcite, quartz sand and industrial paste through proportioning, crushing, ball grinding, drying, shaping and calcine. It can elongate service life of catalyst.

Description

technical field [0001] The invention relates to a protective agent for a catalyst, in particular to a protective agent for supporting and covering a catalyst and a manufacturing method thereof. Background technique [0002] At present, in the burning of petrochemical crude oil, hydrocracking, hydrofining, and various catalysts used in hydrocatalytic devices are scrapped, which seriously pollutes the environment. Contents of the invention [0003] The object of the present invention is to provide a protective agent for supporting and covering the catalyst by utilizing a certain amount of metal components such as molybdenum, nickel, tungsten, and cobalt contained in the spent catalyst and its manufacturing method. [0004] The protective agent for supporting and covering catalysts according to the present invention has the weight percent of its chemical composition: aluminum oxide 34-50; silicon dioxide 47-63; ferric oxide ...
