Problems solved by technology

[0004] However, in catalytic cracking, a large number of olefins are generated after the long molecular chain is broken, which is manifested as an unstable composition. If the esterification reaction is delayed, there will be a deterioration phenomenon; and the esterification reaction has no strong effect on the alkane conversion of olefins, and has no effect. Stable, the olefin content of the produced oil often exceeds the standard; in addition, the use of methanol and acidic substances for esterification reaction has certain process risks, the required reaction time is relatively long, and the process cost is relatively high

Embodiment Construction

[0019] Now in conjunction with the accompanying drawings, the preferred embodiments of the present invention will be described in detail.

[0020] Carboxyl groups and hydroxyl groups of fatty acids, unsaturated hydrocarbons and hydroxyl groups, unsaturated hydrocarbons and hydrogen ions react on a suitable catalytic surface at a certain catalyst surface temperature (120-300°C) to generate alkanes, aromatic hydrocarbons, ketones, aldehydes, components such as esters. According to this theory, the present invention designs the hydration catalytic cracking reaction mode, the basic principle of which is: when the steam of fatty acids and unsaturated hydrocarbons (waste animal and vegetable oils and plastic depolymerized liquefied oil) passes through the SZM molecular sieve catalyst, with the change of catalyst temperature, Long-chain oil and gas molecules are broken into short-chain molecules to varying degrees. When the surface temperature of the catalyst reaches 280°C, C24 chain...

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...
