Embodiment 1-6 and comparative example 1-2

[0032] The preparation of compound kinetic alcohol in embodiment 1-6 and comparative example 1-2

[0033] According to the formula in Table 1, mix methanol, light naphtha, heavy olefins or light aromatics, and acetone, then add n-butanol, lubricant, and benzoic acid in sequence, and stir for 10-20 minutes to obtain the product.

[0034] Wherein, the lubricant is fatty alcohol.

[0035] The above components, heavy olefins or light aromatics can increase the calorific value and octane number of compound power alcohols, fatty alcohols can increase mechanical lubrication, light naphtha can change the physical and chemical properties of methanol, and improve its startability, frost resistance and warm-up performance ; Benzoic acid can reduce corrosion and swelling; n-butanol can make methanol better blend with other components, and enhance the water resistance of compound power alcohol.

[0036] The content units of each component in the following Table 1 are parts by weight.

Abstract

Vehicle-use clean composite power alcohol, relating to the field of fuel, includes, by weight, 30-55 parts of methanol, 20-40 parts of light naphtha, 20-35 parts of heavy olefins and / or light aromatics, 0.05-0.1 parts of a lubricant, 1-3 parts of n-butanol, and 0.00005-0.0001 parts of benzoic acid. A preparation method includes: blending the methanol, light naphtha and heavy olefins and / or light aromatics, successively adding the n-butanol, lubricant and benzoic acid, and stirring the mixture for 10-20 min. The product has excellent startability, power performance, anti-explosion and anti-corrosion properties and stability; corrosivity and swelling property of methanol are reduced. In addition, the product can reduce oil consumption, can be combusted completely without generation of carbonaccumulation and colloid, and can greatly improve safety and stability.

Description

technical field [0001] The invention relates to the field of fuels, in particular to a vehicle-used cleaning compound power alcohol and a preparation method thereof. Background technique [0002] The world's dependence on energy, especially on vehicle energy, has reached an inseparable level, and the limited oil reserves and production volumes are difficult to meet people's growing needs. Oil prices are rising day by day, and people are overwhelmed. The most serious thing is that there is always the danger of oil shortage and cut-off, which threatens the economic security of the country. How to use existing resources and integrate them effectively to supplement or even replace the current petrochemical gasoline and reduce the single dependence on oil has become a research topic. Hot Issues. Methanol is one of the most promising alternative resources, which has good combustion performance and is more environmentally friendly. Methanol gasoline can be obtained by mixing meth...
