Problems solved by technology

However, the main component of this biodiesel is long-chain fatty acid methyl ester, and the presence of oxygen in the product components reduces the calorific value and chemical stability of the fuel, so further deoxygenation is still required to obtain high-grade biofuel.

Abstract

The invention relates to a catalyst for preparing a biological aircraft fuel component from barbados nut oil and a preparation method of the biological aircraft fuel component. The preparation methodcomprises the following steps: 1) soaking nickel salt and molybdenum salt in an MCM-41 molecular sieve carrier, performing air roasting to form a catalyst precursor, and performing hydrogen and methane reduction and carbonization to form the catalyst xCH4-H2 / NiMo / MCM-41 (x is a volume fraction of methane and is equal to 0-0.5), 2) loading the catalyst into a solid bed and feeding nitrogen, hydrogen and the barbados nut oil into the solid bed for reaction at a reaction temperature of 260-360 DEG C, and 3) cooling a reaction product and removing water to form the biological aviation fuel component, wherein a metal loading capacity of the catalyst is 5-40wt.%. In a catalyst activity evaluation experiment, a hydrodeoxygenation conversion rate of the barbados nut oil is 100%, and an aircraft fuel yield can reach up to 72.5%. The catalyst has the characteristics that the catalyst is cheap, easy to obtain, low in reaction temperature and high in catalytic activity and the aviation fuel component is high in yield; and the catalyst has important significance for promoting aircraft fuel development and sustainable energy development.

Description

technical field [0001] The present invention relates to a kind of catalyst that is used to prepare biological aviation fuel component and preparation method thereof, particularly adopts Jatropha oil hydrodeoxygenation to prepare the catalyst of biological aviation fuel and production method thereof. Background technique [0002] Aviation fuel, as one of the transportation fuels whose demand is second only to gasoline and diesel in the world, is an indispensable strategic material for the development of a country and has great market application value. Bio-jet fuel is an important direction for the development of global aviation fuel.
