Problems solved by technology

[0003] However, in the prior art, the cetane number of biofuels is not high enough, the calorific value is relatively low, and the stability is not good enough, and the shelf life is relatively short, which greatly limits the use of biofuels
In addition, the low-temperature flow performance of biofuels is not good enough, which is one of the main factors affecting the normal use of biofuels

Abstract

The invention belongs to the technical field of fuel preparation and in particular relates to a preparation technology of bio-fuel with a good cooling-filtering effect. The preparation technology comprises the following preparation method: 1) taking fatty acid methyl ester; adding 1-hydroxyethylidene-1,1-diphosphonic acid, amino trimethylene phosphonic acid, ethyl acetate and isoamyl butyrate andcarrying out ultrasonic treatment; 2) adding triethanolamine and stirring; 3) enabling a mixture to pass through a hollow fiber membrane to obtain a first permeation solution; enabling the first permeation solution to pass through the hollow fiber membrane to obtain a product. According to the preparation technology provided by the invention, the fatty acid methyl ester, the 1-hydroxyethylidene-1,1-diphosphonic acid, the amino trimethylene phosphonic acid, the ethyl acetate, the isoamyl butyrate and the triethanolamine have a synergistic effect, and the ultrasonic treatment and the hollow fiber membrane are combined to carry out ultra-filtration and the prepared bio-fuel has the remarkable cooling-filtering effect; a cold filter plugging point is improved so that the bio-fuel can be adaptive to a condensation point and the kinematic viscosity of the bio-fuel.

Description

technical field [0001] The invention belongs to the technical field of fuel preparation, in particular to a preparation process of biofuel with good cold filtration effect. Background technique [0002] Today, with the rapid economic development, automobiles have become an indispensable product in people's lives, but some problems that follow are also becoming more and more serious, such as the massive exploitation of petroleum energy and the increasing shortage of petroleum resources, and the impact of automobile exhaust on the environment. pollution. In order to solve the problem of the depletion of petroleum energy, biofuel, as a substitute fuel for fuel oil, has become the most potential new alternative renewable energy. It has the advantages of cleanliness, safety and environmental protection, convenient use, and low cost. It is favored by enterprises and organizations in various countries. It also belongs to the bio-clean new energy that is encouraged to develop durin...
