Abstract

The invention provides a catalyst for reaction of preparing aviation kerosene by castor oil through hydrogenation and a preparation condition of the catalyst. Modified MCM-41, SBA-15 and the like are used as the carrier of a hydro-de-oxygenation catalyst, and one selected from Ni, Ni2P, Co, CoP and Pt is used as an active component; modified SAPO-11, SAPO-34 and the like are used as the carrier of a hydrogenation isomerism catalyst, and one or two selected from Ni, Ag, Pd and Ru is / are used as the active component; the catalyst for the action of preparing the aviation kerosene by the castor oil through a one-step method is characterized in that with one or more selected from modified USY, a beta-type molecular sieve, an X-type molecular sieve and ZSM-5 as the carrier and Ni and Cu as active components or Ni2P and Cu3P as the active components, under a proper reaction condition, the aviation kerosene which meets the need of the operation conditions is prepared.

Description

technical field [0001] The invention provides a catalyst for preparing aviation kerosene through hydrogenation of castor oil and preparation conditions thereof. Among them, the hydrodeoxygenation catalyst is based on modified MCM-41, SBA-15, etc., with Ni, Ni 2 One of P, Co, CoP, and Pt is used as the active component; the hydroisomerization catalyst uses modified SAPO-11, SAPO-34, etc. as the carrier, and one or both of Ni, Ag, Pd, and Ru The catalyst for the one-step preparation of aviation kerosene from castor oil uses one or both of modified USY, β-type molecular sieve, X-type molecular sieve, and ZSM-5 as the carrier, and Ni and Cu as the active component. or Ni 2 P, Cu 3 P is used as an active component to prepare aviation kerosene that meets the conditions of use through appropriate reaction conditions. Background technique [0002] The rapid development of industry has led to a rapid increase in energy consumption, and energy shortage has become an important cond...
