Estimating the term…
The present invention provides a catalytic activity accelerant. The accelerant is added to stock oil for increasing the catalyst activity, the depth of catalytic hydrogenation and the yield of catalytic hydrogenation product, degrading the reaction conditions of catalytic hydrogenation, and improving the quality of product. The catalytic activity accelerant is consisted of an alkyl succinimide derivative, an alkyl phenol and a surfactant. The amount of the alkyl succinimide derivative in the accelerant is 5-70 wt. %. The amount of the alkyl phenol in the accelerant is 2-70 wt. %. The amount of the surfactant in the accelerant is 2-70 wt. %.
A catalytic active accelerant used in petroleum hydrogenation, wherein the catalytic active accelerant is composed of an alkylsuccinimide derivative, an alkylphenol, and a surfactant, wherein the alkylsuccinimide derivative is comprised at 5 to 70%, the alkylphenol at 2-70%, and the surfactant at 2-70% by weight based on the total weight of the catalytic active accelerant and
A catalytic active accelerant composed of:
A method to catalyze petroleum hydrogenation, comprising the operation of contacting petroleum feedstock with a catalytic active accelerant composed of an alkylsuccinimide derivative, an alkylphenol, and a surfactant, wherein the alkylsuccinimide derivative comprises 5 to 70%, alkylphenol 2-70%, and surfactant 2-70% by weight based on the total weight of the catalytic active accelerant the alkylsuccinimide derivative having the following structural formulae:
