  • Patent number: 10493432
    Abstract: Forming a photocatalyst/aerogel composite includes contacting an aerogel including a porous carbon nanotube network with a solution including a photocatalyst precursor to yield a wet gel. The porous carbon nanotube network includes carbon nanotubes, nodes, and struts. Each node is defined by a region in which two of the carbon nanotubes are in direct contact with each other, and each strut is defined by one of the carbon nanotubes extending between a first node and a second node. Forming the photocatalyst/aerogel composite further includes initiating a chemical reaction in the wet gel to form, on the nodes and struts, photocatalyst nanoparticles from the photocatalyst precursor, and removing liquid from the wet gel to yield an aerogel composite defining pores and including the photocatalyst nanoparticles. The photocatalyst nanoparticles are covalently bonded to the nodes and the struts throughout the porous carbon nanotube network.

  • 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.
