Problems solved by technology

However, the emulsification stability of existing emulsifier products is not good enough, and the stability time is mostly only ten days or half a month, so it is difficult to use as a commodity turnover; moreover, most of the existing emulsifier products are refined petroleum products and higher fatty acids. Raw materials lead to expensive emulsifiers, and the cost of producing emulsified diesel remains high

Abstract

The invention discloses a compound emulsifier and an application thereof in producing a micro-emulsified diesel fuel. The preparation of the compound emulsifier comprises the following steps: (1) taking low-quality grease as a raw material and pre-treating; (2) adding methyl alcohol containing dissolved metallic sodium into the pretreated low-quality grease and performing methyl esterification modification, thereby acquiring fatty acid methyl ester; (3) adding a compound aminating agent composed of organic amine and inorganic amine into fatty acid methyl ester, taking metallic sodium as a catalyst and performing amidation reaction, thereby acquiring the compound emulsifier. The invention also discloses an emulsified diesel fuel which is prepared with the compound emulsifier. The compound emulsifier disclosed by the invention is prepared in the manner of taking low-quality grease as the raw material and then performing chemical modification and amidation reaction, so that the productioncost of the emulsifier is effectively lowered. The stability performance and combustion performance of the micro-emulsified diesel fuel prepared with the compound emulsifier are both greatly promoted.

Description

technical field [0001] The invention relates to the technical field of clean energy, in particular to a compound emulsifier and its application in the production of micro-emulsion diesel. Background technique [0002] Emulsified diesel, that is, the combustion of fuel oil mixed with water, although it is not a new topic, but it is constantly giving new thinking and new development momentum. As early as the first annual meeting of the International Combustion Association, it has been confirmed as one of the three major energy-saving measures. Our country has also included it in the development project during several consecutive five-year construction plans, which has set off wave after wave of research boom. [0003] Through continuous theoretical discussions and a large number of experiments in scientific research institutions, many experts and scholars have highly consistent conclusions on the energy saving and emission reduction characteristics of emulsified diesel. Alth...
