Abstract

The vehicle gasoline for replacing petroleum fuel consists of coal-base methanol 20-25 wt%, C2-C8 alcohol 10-25 wt%, low benzene arene 20-35 wt%, dimethoxy methane 5-10 wt%, catalyst 0.01 wt%, coal-base light oil 15-40 wt%, stabilizer 0.01 wt%, and metal corrosion inhibitor 0.01 wt%. The preparation process includes the following steps: 1. reaction of coal-base light oil and catalyst in a distiller, extracting 200 deg.c below fractions, cooling and adding stabilizer; 2. setting the other main materials into a mixer; and 3. pumping the product of the step 1 to the mixer and adding metal corrosion inhibitor to obtain the product. The vehicle gasoline is prepared with coal chemical products and biochemical products, and has high oxygen content, high power performance and capacity of maximizing the released energy.

Description

technical field [0001] The invention belongs to a kind of motor gasoline, in particular to a kind of motor gasoline which replaces petroleum raw materials and a preparation method thereof. Background technique [0002] With the increase of car ownership in the market, fuel demand has risen sharply, especially the oil crisis that occurred in the 1970s, which accelerated the research process of alternative fuels for vehicles in various countries. Shanxi Province organized a large-scale methanol blending test, and several M15 methanol-gasoline deployment centers have emerged. M15 methanol gasoline has been recognized by the society after being sold in batches in the Shanxi market. However, methanol gasoline containing a high proportion of methanol has the problems of poor cold start, poor power performance, air resistance, and is not suitable for use in extreme cold, high temperature, anoxic, and high humidity environments. Contents of the invention [0003] The present inv...
