Abstract
The invention relates to methanol gasoline for vehicles and a preparation method thereof, belonging to the technical field of the petrochemical industry. The methanol gasoline for vehicles is prepared from the following raw materials in percentage by weight: 70-85 percent of gasoline, 10-25 percent of methanol, 0.5-8 percent of petroleum ether, 0.1-2.5 percent of ferrocene, 2,2,3',3'-tetramethylbutane, 0.1-2 percent of di-tert-butyl, 0.5-6 percent of methyl tert-butyl ether, and the like. The preparation method comprises the following steps of: preparing an additive; preparing denatured methanol; and mixing with gasoline and stirring to obtain methanol gasoline for vehicles. By adding some common reagents, the prepared methanol gasoline for vehicles is suitable for various vehicles, has favorable cold start without depositing carbon and clean and environment-friendly exhaust emission without changing the vehicle structure, can be used singly or used with various current brands of gasoline and has favorable economy and market prospects.
Description
technical field [0001] The invention relates to methanol gasoline for vehicles and a preparation method thereof, belonging to the technical field of petrochemical industry. Background technique [0002] In today's world, the demand for energy is increasing day by day. With the development of industry, the energy structure is constantly changing. Traditional oil and natural gas resources are increasingly scarce, and seeking alternative energy sources will become the key to future world economic development. In my country's entire oil consumption market, the consumption of gasoline and diesel has exceeded 50% of the total consumption, of which transportation fuels account for more than 70%, which is also the key to the contradiction of my country's energy structure. [0003] In order to alleviate the pressure brought by the shortage of oil resources, the development of new energy sources for vehicles has become an effective method. As a new alternative fuel, alcohol fuel ha...
