  • Publication number: 20210363095
    Abstract: The disclosure is about a method capable of realizing the preparation and in-situ separation of the oligomeric ricinoleate, which uses the ricinoleic acid as raw material, and uses a protonic acid-type ionic liquid as a catalyst to cause the dehydration and esterification reactions between ricinoleic acid molecules. By continuously distilling out the generated water under a reduced pressure, the oligomeric ricinoleate with a polymerization degree of 2 to 10 is obtained. After the reaction, a method of washing with water or static stratification is selected to recover the catalyst according to the miscibility of the catalyst and reaction system. In his disclosure, renewable raw materials are used, the process is clean and pollution-free, and the operation is simple.

  • Patent number: 10479944
    Abstract: A hydrodeoxygenation catalyst takes self-made porous large-specific surface nano-alumina as a carrier, takes NixMoW, NixCoW or NixCoMo as an active component, and takes Mn as an assistant. Hydrothermal stability of the catalyst and dispersion of active components may be increased by enlarging a pore channel and a specific surface area of the carrier, thereby prolonging the life of the hydrodeoxygenation catalyst. A hydroisomerization catalyst takes multi-walled carbon nanotube composite hierarchical-pore-channel NiAPO-11 or NiSAPO-11 as a carrier and takes NixMoLa, NixCoLa or NixWLa as an active component. Due to the adding of the carbon nanotubes, the pore channel of the carrier is enriched, and connection between the active components and the carrier is effectively enhanced, thereby prolonging the life of the catalyst on a basis of increasing selectivity of aviation kerosene component. Moreover, the biological aviation kerosene satisfying usage conditions is prepared by virtue of mild reaction conditions.

  • Patent number: 10399069
    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 NixW and NixMo 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.
