标题 :Process for the preparation of a catalyst for a catalyst precursor
发明人:REK PAULUS JOHANNES MARIA; BLANKENSTEIN PAUL
权利人:SHELL INT RESEARCH
摘要:A process for the preparation of a catalyst or catalyst precursor, comprises mulling a mixture comprising a refractory oxide or refractory oxide precursor, a solvent and a peptising agent; adding to the mixture a neutralising agent, which neutralising agent is a source of a catalytically active component; and extruding the resulting mixture. The process is particularly suited to the preparation of catalysts comprising as catalytically active components metals from Group VIII, which catalysts are useful in the synthesis of hydrocarbons from a mixture of carbon monoxide and hydrogen.

摘要:The present application provides a supported composite metal catalyst, and a preparation method therefor and a use thereof. The catalyst comprises an acidic oxide support, at least one noble metal, and at least one base metal. The acidic oxide support is strong acid acidified ZrO2, the noble metal is selected from Pt, Pd, Rh, Ru, or a combination thereof, and the base metal is selected from at least one of the following: Ni, Co, Mn, Ce, or Cu. A synthesis method for the catalyst comprises the steps of forming the acidic oxide support, forming a slurry by using raw materials of the noble and base metals and the acidic oxide support, spray drying, and heating treatment. The catalyst can be used to perform complete catalytic oxidative decomposition of volatile organic compounds under a suitable condition, or even at a high moisture level. The technology of the present invention has the advantages of a low use amount of noble metals, excellent low-temperature catalytic oxidation performance, good high-temperature stability, and easy industrial-scale production, and therefore, the volatile organic compounds in exhaust gas can be completely converted into harmless water and carbon dioxide at a relatively low reaction temperature, so that even under a high exhaust gas water vapor content, the catalyst still has extremely high stability.
