Abstract

The invention relates to the field of biodiesel, and in particular, relates to a production method of branched biodiesel, wherein the production method comprises the steps: mixing biodiesel and formic acid, stirring and heating to 40-60 DEG C, and dropwise adding a catalyst and hydrogen peroxide mixed solution, to obtained epoxidized biodiesel; and carrying out a mixing reaction of the epoxidized biodiesel and fatty alcohol to obtain branched biodiesel, wherein the mass ratio of the epoxidized biodiesel to the fatty alcohol is 1 to 5, and the amount of concentrated phosphorus acid is 1% of the mass of the epoxidized biodiesel. The production method of the branched biodiesel improves the oxidation stability and low temperature fluidity of the biodiesel, and has the advantages of low process and equipment requirements, simple operation and mild reaction conditions.

Description

A kind of Composite acid catalyst for esterification of biodiesel
Technical field
The present invention relates to field of biodiesel oil is and in particular to a kind of Composite acid catalyst for esterification of biodiesel.
Background technology
The raw materials for production of domestic biodiesel are mostly waste grease (waste oil, hogwash fat, acidification oil etc.), waste grease In contain substantial amounts of free fatty, if directly preparing biodiesel by ester exchange is carried out using base catalysis, can lead to catalysis imitate Rate is low, and saponification phenomenon is seriously it is impossible to obtain effective product.The content reducing free fatty in feedstock oil is production of biodiesel Necessary condition, be one of the most effectual way reducing free fatty using acid-catalyzed esterification reaction.The most normal in actual production Esterification catalyst is sulfuric acid, and sulfuric acid has preferable catalysis activity, but has stronger oxidation and deep-etching simultaneously Property.Sulfuric acid and feedstock oil can occur a series of side reactions during the course of the reaction, by part material oil carbon or aggregate into colloidal substance Material, and the necessary special disposal of a large amount of acid sludges that esterification generates after terminating, cost is larger.Deep-etching due to sulfuric acid Property it is desirable to reactor must be enamel reaction still, to reaction after generate useless methyl alcohol and the material such as methanol recovery system, hold-up tank Require also higher it is necessary to use 316L stainless steel.
Content of the invention
The technical problem to be solved is the shortcoming overcoming existing catalyst for esterification reaction to exist, and provides one kind (rapeseed oil, soybean oil, recovery cooking oil, fats and oils processing inferior horn oil plant etc. are natural to be applied to the higher various animal and vegetable oil of acid number Oil) esterification, catalyst amount is few, high catalytic efficiency, the free from corrosion Composite acid catalyst for esterification of biodiesel to equipment.
The technical solution adopted in the present invention is：
A kind of Composite acid catalyst for esterification of biodiesel it is characterised in that：Including following material by weight 1 part of tin methane sulfonate, 0.5 part of beta-naphthalenesulfonic-acid, 0.1 part of four iron oxide, 0.1 part of trioctyl phosphate.
A kind of Composite acid catalyst for esterification of biodiesel that the present invention provides, consumption is few, and catalysis activity is high, in course of reaction No other accessory substances generate.
Specific embodiment
The present invention is further illustrated with reference to embodiments, but the present invention is not limited only to these embodiments, not On the premise of departing from present inventive concept, any improvement made is within the scope of the present invention.
A kind of Composite acid catalyst for esterification of biodiesel it is characterised in that：Including following material by weight 1 part of tin methane sulfonate, 0.5 part of beta-naphthalenesulfonic-acid, 0.1 part of four iron oxide, 0.1 part of trioctyl phosphate.
