Abstract:
The present invention relates to a hydroisomerization and cracking catalyst for preparing biological aviation kerosene from castor oil as well as a preparation method and an application thereof. The catalyst takes a Al-modified titanium silicate molecular sieve (TS-1) as a carrier, and takes Ni x W and Ni x Mo as active components, wherein x is the atomic ratio of Ni to W or Ni to Mo, and x=5-10, wherein the mass of the active components accounts for 5-30% of the total mass of the catalyst; the molar ratio of Si:Ti in the Al-modified titanium silicate molecular sieve is 50-100, and the molar ratio of Si:Al is 50-100.

Claim (Index 8):
A using method of the catalyst of  claim 1 , comprising the following steps:\n 1) pretreatment of the catalyst: forming a catalyst of a required amount and then filling the catalyst in a fixed bed reactor; heating to 400-450\u00b0 C. under nitrogen purging with volume space velocity of 800-1200 h-1; changing into hydrogen with the same volume space velocity; maintaining the temperature of 400-450\u00b0 C. for at least 3 hours; and then regulating the temperature of the reactor to a temperature of a hydroisomerization and cracking reaction; and 2) hydroisomerization and cracking reaction: taking an anhydrous liquid product obtained after the hydrodeoxygenation of the castor oil as raw oil for the hydroisomerization and cracking reaction; regulating a pressure of a reaction system to 2-4 MPa, a reaction temperature to 270-350\u00b0 C., a hydrogen-oil ratio to 700-1500, and volume space velocity of the fed raw oil to 1-3 h-1; and collecting a liquid product obtained in the reaction every 2 hours,
