Abstract
The invention discloses a preparation method of a castor-oil plant based biological aircraft fuel. According to the method, castor oil is selected as a raw material, an appropriate catalyst is prepared, and a hydrodeoxygenation reaction and a hydroisomerization reaction are carried out. The preparation method specifically comprises the following steps: hydrogen is blown into castor oil in the presence of a hydrodeoxygenation catalyst so as to generate n-alkanes; hydrogen is blown into n-alkanes in the presence of a hydroisomerization catalyst so as to isomerize to generate isoparaffin; and a fraction is subjected to fractionation so as to obtain the final product. The final product is the biological aircraft fuel which accords with usage requirements (such as American ASTMD7566 standard and the like). The obtained product castor-oil plant based biological aircraft fuel contains no alkene or napthene. By the adoption of the fuel, carbon formation of a motor is remarkably reduced. In addition, the fuel contains no sulfur compounds. When the fuel is in use, environmental pollution will not be caused. The castor-oil plant based biological aircraft fuel is an alternative for replacing a petrochemical aircraft fuel.
