Additive and its vehicular methanol diesel oil and preparing method

Abstract

The invention discloses an additive and automotive methanol diesel oil thereof and a preparation method of the methanol diesel oil. The additive comprises (by wt%) mixed fatty acid esters 15, unsaturated fatty acids 7, mixed fatty acids 15, castor oil 2.8, a palmitic acid 5, a cetane number improver 0.1, C4 to C10 fatty alcohols 30, a corrosion inhibitor 0.03, ethyl acetate 11, a combustion improver 0.06, butyl acetate 9, a dispersant 0.01 and hydrogenated ricinoleic acid 5. The methanol diesel oil comprises (by wt%) methanol 10 to 30, biological diesel oil 18 to 34, standard diesel oil 26 to 67 and the additive of the invention 5 to 10. The preparation method of the methanol diesel oil comprises the following steps of: adding methanol and the additive of the invention into a mixing tank at the ratio, mixing, sequentially adding the biological diesel oil and the standard diesel oil into the mixing tank at the ratio and mixing uniformly. The additive has the advantages of low material cost and simple preparation process, and the methanol diesel oil has the advantages of stable performance, low cost, simple preparation method and easy popularization.

Description

technical field [0001] The invention relates to an additive, methanol diesel for vehicles and a preparation method thereof. Background technique [0002] Diesel, as a kind of energy, is widely used in various fields, and the amount of diesel used in vehicles is very large. Due to the high thermal efficiency, good emission performance, high low-speed torque, good durability and reliability of diesel engines, especially the high fuel economy and low emission characteristics of diesel engines, it has become an irreversible trend in the international community to use diesel engines for vehicle power. Therefore, diesel vehicles are increasing year by year, the supply gap of diesel is also increasing, and the price is also rising step by step. How to solve the shortage of diesel and reduce costs is a problem that people generally face. Automobile exhaust is one of the main pollution sources leading to urban pollution and global warming. 60% to 70% of air pollution is caused by au...
