摘要:
Disclosed are catalysts for hydrotreating hydrocarbons and methods for preparing the same, and the catalyst is composed of a carrier substance consisting essentially of an oxide of aluminium and/or an oxide hydrate of aluminium, at least one selected from water-soluble compounds of metals of Group VI and Group VIII of the Periodic Table and at least one organic compounds selected from mercapto-carboxylic acids of formula HS-(CH₂) n -COOR (where n is 1 to 3; R is H, alkali metal, alkaline earth metal or ammonium gorup or alkyl group with 1-10 carbons), thio-acids of formula R′-COSH (where R′ is monovalent hydorcarbon with 1-15 carbons), amino-substituted mercaptans of formula H₂N-R˝-SH (R˝ is divalent hydrocarbon with 1-15 carbons), dimercaptans of formula HS-R˝-SH (R˝ is same as above) and mercapto-alcohols of formula (RaS-R‴-(OH) n (where R‴ is hydrocarbon with 1-15 carbons; Ra is H or alkyl group with 1-2 carbons; and n is 1-2), and optionally phosphoric acid. The catalyst requires neither presulfurization nor heat-treatment and can directly be applied to hydrotreating hydrocarbons.
摘要:
New supported catalysts for hydrotreating hydrocarbons comprise (a) at least one member selected from the group consisting of oxides of metals in the Periodic Table's Groups VI and VIII, and (b) at least one organic compound having a mercapto radical or radicals ( -SH ) selected from the group consisting of mercapto-carboxylic acids ( including alkali metal, alkaline earth metal and ammonium salts thereof, and esters thereof ), bivalent mercaptans, amino-substituted mercaptans, and thiocarboxylic acids. These new catalysts can be easily activated by treatment in the presence of hydrogen gas at a temperature in the range from room temperature to 400°C, showing higher activity than those activated by conventional methods.

摘要:
There is disclosed a catalyst which hydrotreats hydrocarbons without need of presulfiding The catalyst comprises a carrier of an inorganic oxide containing a sulfurizing agent and a water-soluble compound of two metals one of which belongs to the Group VI of the Periodic Table, while the other belongs to the Group VIII. The carrier has pores in which a precursor of a sulfide is formed. The coordination number of the closest Group VI metal found from the radial distribution function around the Group VI metal is less than 0.25. The function is obtained from the Fourier transform of the extended x-ray absorption fine structure of the precursor.
