Abstract

The invention provides a method for preparing hydrodeoxygenation and hydroisomerization catalysts for biological aviation kerosene from camelina oil. In the hydrodeoxygenation catalyst, modified SBA-15 serves as a carrier, one of Nix-Mo and Nix-Co serves as an active component, and polyethylene glycol 200 serves as a dispersing agent, so that the service life of the catalyst is prolonged to 350 hours. In the hydroisomerization catalyst prepared by a microwave synthesis method, one of hierarchical porous NiAPO-11, hierarchical porous NiSAPO-11, hierarchical porous SAPO-11, microporous NiAPO-11 or microporous NiSAPO-11 serves as a carrier, one of Pd or Pt serves as an active component, and polyethylene glycol 200 serves as a dispersing agent. The biological aviation kerosene which is accordant with use conditions is prepared under a mild reaction condition.

Description

technical field [0001] The invention proposes a method for preparing a hydrodeoxygenation and hydroisomerization catalyst for bio-aviation kerosene from flax mustard oil. Among them, the hydrodeoxygenation catalyst is supported by modified SBA-15, with Ni x -Mo, Ni x -One of Co as the active component, with polyethylene glycol 200 as the dispersant, the catalyst life was extended to 350 hours; the hydroisomerization catalyst was synthesized by microwave, and NiAPO-11 with multi-level channels , NiSAPO-11 with hierarchical channels, SAPO-11 with hierarchical channels, NiAPO-11 with micropores or NiSAPO-11 with micropores as the carrier, and one of Pd or Pt as the active component, Using polyethylene glycol 200 as a dispersant, under mild reaction conditions, bio-aviation kerosene meeting the conditions of use was prepared. Background technique [0002] The energy crisis is getting more and more attention from human beings, which usually involves the shortage of oil, electr...
