Coal-based methanol gasoline for M25 car

Abstract

The invention provides coal-based methanol gasoline for a car. The coal-based methanol gasoline consists of the following components in percentage by mass: 20% of coal-based methanol, 79.94% of gasoline-based basic component oil, 0.01% of metal deactivator, 0.05% of antioxidant, wherein the gasoline-based basic component oil consists of the following components in percentage by weight: 10-18% of hydrogenation light component oil, 10-15% of pentane-removed oil, 20-30% of C7 or C9, 0-9% of C5, 9-14% of raffinate oil, 3-14% of MTBE, 4% of isoamyl alcohol, 1% of octyl alcohol and 0.3% of dioctyl sebacate. The car methanol gasoline disclosed by the invention effectively solves and inhibits a problem that the methanol gasoline for the M25 car is difficult to start at low-temperature, great in high temperature gas resistance, insufficient in power, corrosive and swelling; except methanol content index, other indexes of the blended finished product oil satisfy standards of national GB18351-2013 Car Methanol Gasoline, and parts of the indexes are superior to those of associated local standards.

Description

technical field [0001] The invention relates to fuel oil, in particular to methanol gasoline for vehicles. Background technique [0002] Due to the shortage of oil resources in our country, the alternative research of non-fossil energy has become a major topic of concern. my country is a big coal producing country. The comprehensive utilization of coal-based methanol is an important branch of the coal chemical industry chain. The development and utilization of methanol resources as a substitute for transportation fuel is an effective and important measure. Methanol is one of the downstream products of high-efficiency conversion and utilization of coal, and it can be prepared into methanol gasoline by adding it to gasoline in a certain proportion. [0003] In addition to its high economic benefits, methanol gasoline also effectively controls the pollution source of PM 2.5. The harmful substances in the exhaust gas are greatly reduced, the octane number is increased, the olef...
