Abstract

The invention discloses a method for preparing biomass fuel from nanometer materials under catalytic cracking. The method comprises the following steps: performing dehydration treatment on such raw material oil as swill-cooked dirty oil, acidic oil, waste animal and vegetable grease, and separating to remove water and impurities; pumping the dehydrated grease into a tubular heating furnace by a high-temperature oil pump so as to gasify the grease to form a grease vapor and heavy oil mixture, separating the heavy oil by a catalytic fractionating tower at the bottom of the tower, performing catalytic cracking reaction on the pure grease vapor by a catalyst layer, reducing the molecular weight of the grease, removing groups, such as carboxyl and glycerinum, from the grease molecules, and generating hydrocarbon-type oil, liquefied gas and combustible gas; performing preliminary purification on the diesel part of the hydrocarbon-type oil by a steam stripping method and then performing deacidifying stable coalescence treatment; and adsorbing by an adsorbent and separating to obtain biodiesel and biogasoline. The method provided by the invention has the characteristics of high universality, easily available material, excellent property, wide application, simple process, high quality consistency, high additional value and low cost.

Description

technical field [0001] The invention relates to the technical field of biodiesel and fuel, in particular to a method for preparing biomass fuel by catalytic cracking. Background technique [0002] The raw material for biodiesel extraction comes from automatic and vegetable oils, which are widely used in tractors, trucks, ships, etc. It refers to oil crops such as soybeans, rapeseed, cotton, palm, etc., wild oil plants and engineering microalgae and other aquatic vegetable oils, animal fats, and catering waste oils, etc. Renewable diesel fuel to replace petrodiesel. Biodiesel is a kind of biomass energy, which is a mono-alkyl ester of long-chain fatty acid obtained from biomass by pyrolysis and other technologies. Biodiesel is a mixture of complex organic components with high oxygen content. These mixtures are mainly organic compounds with large molecular weight, such as fatty acid methyl esters, cetane, octadecane, etc. Composite biodiesel is synthesized by using waste an...
