A hydrodeoxygenation catalyst takes self-made porous large-specific surface nano-alumina as a carrier, takes Ni.sub.xMoW, Ni.sub.xCoW or Ni.sub.xCoMo 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 Ni.sub.xMoLa, Ni.sub.xCoLa or Ni.sub.xWLa 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.

Disclosed is a method of preparing a drilling fluid and lube base oil using biomass-derived fatty acid, including hydrogenating a fatty acid mixture derived from fat of biological origin so as to be converted into a fatty alcohol mixture, which is then dehydrated to give a C16 and C18 linear internal olefin mixture, which is then oligomerized to give olefinic lube base oil, followed by hydrofinishing to remove the olefin, yielding high-quality lube base oil (e.g. Group III or higher lube base oil). The C16 and C18 linear internal olefin mixture, which is a reaction intermediate, can be utilized as a high-quality drilling fluid.
