Problems solved by technology

However, after research and analysis, it is found that they all have their own disadvantages: some additives are too much, more than 10%, and the price of additives is much higher than that of gasoline, so they have no economic value. However, some of them cause pollution to the environment and are therefore banned from use. For example, tetraethyl lead has been banned in China, MTBE (methyl tert-butyl ether), etc. have been banned abroad and will soon be banned in China. Use: Some preparation methods have defects, and the prepared methanol gasoline is easy to deteriorate

Abstract

The present invention relates to a kind of methanol gasoline and its preparation method. Isopropyl ether, benzene or toluene or xylene, iron naphthenate or iron pentacarbonyl, silicon aluminum phosphate or sodium dihydrogen phosphate, RP97 composite detergent and dispersant, carboxylate or sulfonate, silicon-type molecular sieve. The preparation must be carried out under normal temperature, normal pressure, non-spark, fireproof and explosion-proof environment. The steps are as follows: add isobutanol or isopropanol to benzene or toluene or xylene, and then add diisopropyl alcohol together Synthesize co-solution A in ether; add gasoline or light hydrocarbon or straight-run oil into methanol, and mix to form main solution B; mix and stir solution A and solution B to form solution C; then add other additives in turn, and stir evenly; Just filter. It has the advantages of low cost, high octane number, good stability, storage period of more than one year, and environmental protection. The preparation process is simple, and products of various labels can be prepared.

Description

technical field [0001] The invention relates to fuel technology, in particular to a methanol gasoline and a preparation method thereof. Background technique [0002] In today's world, the rapid development of the transportation industry is the precursor to the rapid development of the economy and society, and the rapid development of the transportation industry depends on the rapid development of the oil industry and its related industries. Therefore, the demand for oil is increasing day by day. Because oil resources are non-renewable precious resources, the world is facing a serious crisis of oil resource depletion at hand. This unavoidable development trend has already attracted the attention of the world. Since the 1970s, countries around the world have successively invested a lot of manpower, material and financial resources to carry out research on oil substitutes. So far, in addition to water energy and nuclear energy, the use of methanol or ethanol and gasoline to p...
