Abstract

The invention provides a method and an apparatus for refining biomass fuel oil by a hydration catalysis means. The method comprises the following steps: a molecular sieve catalyst is used, water vapor is introduced for carrying out a catalytic cracking reaction, and a hydration catalytic cracking reaction is formed; water vapour is directly involved in the reaction in order to accomplish formation of alkanes from unsaturated hydrocarbons, and an esterification reaction of fatty acid and oleic acid is accomplished synchronously. The method has a simple process, the quality of the product is stable, and the method and the apparatus are better suitable for refining biomass fuel oil from waste oil and fat of animals and plants as well as waste plastics.

Description

technical field

[0001] The invention relates to a method and a device for refining biomass fuel oil, in particular to a method and device for refining biomass fuel oil by means of hydration catalysis. Background technique

[0002] Biodiesel generally uses vegetable oils to undergo esterification to produce fatty acid methyl esters, which are then distilled to obtain biodiesel. Due to the relatively long molecular chain of vegetable oil fatty acid, the fatty acid methyl ester produced has a relatively high freezing point and solidifies into a paste at room temperature, thus limiting the scope of use of the product. Conventionally produced biodiesel can only be used as a chemical reagent and cannot be used as a normal product. Diesel fuel use.

[0003] When choosing waste animal and vegetable oils as raw materials for refining, in the refining process, the molecular chains of vegetable oils are firstly reformed by breaking chains, and then SZM molecular sieve catalysts are se...
