Abstract

The invention discloses a highly clear methanol gas composition and its process for preparing. The said composition includes the following components: gas, carbinol and assisting solvent, in which the assisting solvent comprises methyl tert-butyl ether, toluene, 32# white oil, capryl alcohol, isobutanol, cleaning disperser, and corrosion inhibitor. The invented methanol gas has solved many problems existed in the prior methanol gas, has reduced the pollution to the environment caused by the traditional exhaust gas and largely improved the carbinol content, according to the percentage by weight, the carbinol content can reach 28.5 %-57 %, the methanol gas can not be stratified when storaged for 6 months at -10 DEG C-35 DEG C, and the invention has overcome the problems that the traditional methanol gas can cause corrosion to the engine and the oil pipeline and the spray bar are prone to block up. The process for preparing methanol gas of this invention is simple and easy to proceed.

Description

Technical field: [0001] The invention relates to a liquid carbon-containing fuel, in particular to an additive-containing liquid carbon-containing fuel and a preparation method thereof. Background technique: [0002] With the rapid development of the national economy, the output of automobiles continues to rise, and the number of automobiles in our country has greatly increased. Followed by a sharp increase in vehicle exhaust emissions, exhaust pollution presents a very serious situation. At the same time, due to the limitations of crude oil reserves and exploitation, gasoline prices continue to increase. Objectively, there is a need for an energy source that is cleaner, more widely sourced, and cheaper than gasoline. Therefore, in recent years, people continue to explore the use of new energy sources to replace or improve gasoline. [0003] Methanol gasoline and ethanol gasoline products came into being. In contrast, methanol gasoline has better application prospects th...
