Abstract

This invention relates to a method for preparing biological liquid fuel oil from rice bran wax. The biological liquid fuel oil is prepared from rice bran wax and antioxidant (0.01-0.5 wt. %). The method comprises: performing catalytic pyrolysis and catalytic fractionation on rice bran wax in the presence of petroleum pyrolysis catalyst, decoloring with 3A molecular sieve, and adding the antioxidant. The obtained biological liquid fuel oil is similar to mineral oil in the properties, and has such advantages as good atomization effect, adequate combustion, easy cold start in winter, no need for combination with other fuels, low cost, and simple process.

Description

technical field [0001] The invention relates to a biological liquid fuel oil and a preparation method thereof. Background technique [0002] The development and utilization of biological liquid fuel oil is a promising and practical undertaking. It enables us to reduce our dependence on petrochemical energy, and plays an important role in environmental protection, economic growth, and sustainable development of natural resource utilization. However, the shortcomings of biological liquid fuel oil itself limit the application degree. First of all, because of the relatively large molecular weight of oil, the carbon chain length of biological liquid fuel oil is mostly between 16-24 carbon atoms, while the carbon chain length of mineral diesel oil is generally 8-10 carbon atoms. Due to the high viscosity of bio-liquid fuel oil, the injection timing is affected, resulting in poor injection effect. Secondly, due to the flexibility of biological liquid fuel oil, it is not easy to ...
