Abstract

The invention discloses a hydrodeoxygenation catalyst for an organic oxygen-containing compound of an oil product as well as a preparation method and an application thereof, and belongs to the technical field of oil product refinement. The preparation method for the low-nickel catalyst is a sol-gel method; the catalyst is a low-nickel-based catalyst; the loading amount of the active components of the catalyst is 5-25% (wt); the catalyst also comprises one or more of transition metal as an additive; a catalyst carrier is TiO2-SiO2 composite oxide; and the molar ratio of Ti to Si is 1:(1-20). The prepared catalyst is low in cost, high in activity and high in hydrodeoxygenation conversion rate.

Description

technical field [0001] The invention relates to a hydrogenation deoxygenation catalyst of an oil organic oxygen-containing compound, a preparation method and an application thereof, and belongs to the technical field of oil refining. Background technique [0002] With the consumption of petroleum resources, the energy situation and fuel energy situation are getting tighter day by day, countries all over the world are stepping up research on alternative energy sources. Alternative oil products such as F-T synthetic oil and biomass oil are faced with high oxygen content, resulting in poor oil quality. Therefore, oil must be refined to improve oil quality. [0003] At present, the main method of oil refining is catalyst catalytic hydrodeoxygenation. Much research has been done on organic oxygenate hydrodeoxygenation catalysts. However, the sol-gel method to prepare low-nickel content catalysts is rarely used in the hydrodeoxygenation of organic oxygen compounds. Duan Yan et...
