Problems solved by technology

There are many kinds of additives for preparing denatured alcohols on the market, but their cost is high, and when the ratio of blended denatured alcohols exceeds 15% by weight of naphtha or gasoline, there will be alcohol-oil stratification, high-temperature air lock and winter It is difficult to start cold, and the amount of additives will increase exponentially when denatured alcohol is prepared in cold weather

example 1

[0016] This example is to prepare the additive of the present invention, concrete consumption (weight ratio):

[0017] Acetone 4%, toluene 90%, isobutanol 1%, benzoic acid 2%, ferrocene (ferrocene) 1%, zinc peroxide 2%.

[0018] making process:

[0019] Under the condition of normal temperature and pressure, add 4% acetone, 90% toluene, 1% isobutanol, 2% benzoic acid, 1% ferrocene (ferrocene) and 2% zinc peroxide to the container, after fully stirring Finally, the yellow transparent liquid product obtained is the desired additive product.

example 2

[0021] This example is the concrete application of the additive product that example 1 makes.

[0022] Add 1.5% by weight of the additive product of Example 1 to methanol and stir well to obtain denatured alcohol.

example 3

[0024] Add the denatured alcohol product of Example 2 of its weight 15% in the national standard No. 90 unleaded gasoline, fully stir and promptly make M15 methanol gasoline for vehicles.

[0025] The M15 methanol gasoline for vehicles has been tested by the Shanxi Provincial Product Quality Supervision and Inspection Institute and issued a test report (report number: S20051411, test basis: DB14 / T92-2002), and its physical and chemical properties are shown in Table 1. It can be seen from the data in Table 1 that the gasoline octane number increases by 4 units.

[0026] The bench test report (No.: QS[2006]001) done by the Automobile Product Quality Supervision and Inspection Station of the Shanxi Province Quality and Technical Supervision Bureau on the M15 methanol gasoline prepared in this example shows that:

[0027] At low idle speed (800rpm), the detection of CO is 55.6% lower than that of No. 90 unleaded gasoline, and that of HC is reduced by 43.5%. Such a result is quite...

Abstract

The invention relates to a methanol gas oil modification alcohol additive that uses acetone, toluol, isobutyl alcohol, benzoic acid, ferrocene and zinc peroxide as raw material, and whisking equal in the volume under room temperature and normal pressure to gain the product. It adds 1-3% additive into methanol to gain modified mellow after whisking, and adding the mellow into naphtha or 90# diesel oil to gain the 90#, 93#, 97# and 98# methanol gas oil. The gas oil condensation point would be decreased by adjusting the methanol gas oil and the pollution would be sharply decreased. It has great social benefits and economic benefits.

Description

technical field [0001] The invention relates to an additive for producing denatured alcohol (the raw material required for preparing methanol gasoline for vehicles), more precisely, it is a kind of additive that is added to methanol to generate denatured alcohol, and then added with 20 to 40% by weight It is an energy-saving additive product that is blended into naphtha or gasoline; naphtha or gasoline blended with this denatured alcohol can significantly reduce CO and HC compounds in vehicle exhaust, so it is an environmentally friendly additive products. Background technique [0002] Under the background of increasing shortage of petroleum and other disposable energy sources and increasingly severe environmental pollution, methanol gasoline, which is prepared by adding denatured alcohol and naphtha or gasoline in a certain weight ratio, is used as a kind of cheap and good combustion efficiency. Vehicle fuel alternative energy can effectively reduce my country's oil imports...
