Abstract

A biodiesel composite catalyst consists of dodecylbenzene sulfonic acid and p-toluene sulphonic acid, wherein, the dosage of the dodecylbenzene sulfonic acid is 60-80 percet; the dosage of the p-toluene sulphonic acid is 20-40 percent; the raw materials only need to be stirred uniformly under normal temperature and pressure. The composite catalyst made by adopting the present invention has very strong catalytic activity in the esterification reaction process of oil and methanol, and has a certain emulsification to the oil and the methanol, which is beneficial to promote the oil and the methanol to contact closely and can greatly improve reaction efficiency.

Description

Technical field [0001] The invention belongs to the field of liquid fuel processing, in particular to a catalyst in the biodiesel esterification reaction process. technical background [0002] The technology of making biodiesel with various animal and vegetable oils and methanol under the action of a catalyst has been popularized and applied by many enterprises, but most of the catalysts used in the prior art use a single acid or alkali catalyst, such as sulfuric acid or hydrogen sodium oxide, etc. Due to the lack of good compatibility between oil and methanol, that is, insufficient crosslinking, which greatly affects the degree and efficiency of the esterification reaction, it is necessary to use a multifunctional catalyst. Contents of the invention [0003] The invention provides a composite catalyst with both high-efficiency catalytic performance and cross-linking performance, thereby greatly improving the rate and conversion rate of the esterification reaction.
