Description

A kind of methanol gasoline and compound method thereof

Technical field

The present invention relates to a kind of gasoline prescription and compound method, particularly relate to a kind of methanol gasoline and compound method thereof.

Background technology

Tellurian petroleum resources are limited, and be a kind of non-renewable energy, it is predicted: the average life of world oil exploitation approximately is 30 years, its Middle and North America 9.6 years, West Europe 17.9, USSR (Union of Soviet Socialist Republics) 15 years, Africa 29.5, the Middle East 93.8, Asia (not comprising China) 15.6, South America 34.5, China 30 years.This pessimistic estimation makes oil become the energy of worldwide competition more, and automobile emission regulation is more and more harsher in recent years in addition, thereby seeks a kind of cheap and easy to get, fuel substitute that pollution is few for automobile, is of great immediate significance.Aalcohols fuel is considered to the most promising motor car engine fuel substitute owing to its combustion heat value height, pollution are few, and this is confirmed by many experts' institute, and has now obtained using quite widely Europe, North America and South America.Methyl alcohol is a kind of reproducible energy, and its wide material sources, and it is also ripe to produce the technology of methyl alcohol, methyl alcohol have more superiority again with its good physico-chemical property, store and transportation property easily than other alternative motor fuels.Present stage if can be implemented under the situation that does not change any component of vehicle, can use methanol gasoline, will be promoted and obtain huge social benefit and economic benefit rapidly.Yet methyl alcohol and gasoline mixing are mixed to burn and are had many problems, such as: methyl alcohol and gasoline are difficult for dissolving mutually, and fuel combustion is insufficient, calorific value is low; Automobile uses the back influence engine life, ejecta insufficient certain pollution that has of burning.

Summary of the invention

A kind of novel high-cleaness methanol gasoline that the present invention works out in order to solve the problems of the technologies described above just, and design a kind of method of special this high-cleaness methanol gasoline of preparation for this reason.

The technical solution adopted for the present invention to solve the technical problems is: a kind of methanol gasoline, not only comprise methyl alcohol and 90# gasoline, also comprise petroleum naphtha, Virahol, benzene mixed, sherwood oil, propyl carbinol and isooctyl alcohol, its by weight per distribution ratio be methyl alcohol 25-35%, 90# gasoline 40-50%, petroleum naphtha 15-25%, Virahol 1.5-2.5%, benzene mixed 1-2%, sherwood oil 0.1-0.5%, propyl carbinol 0.1-0.4% and isooctyl alcohol 0.1-1%.

Described methanol gasoline, more excellent proportioning is: it is methyl alcohol 30%, 90# gasoline 45%, petroleum naphtha 20.5%, Virahol 1.9%, benzene mixed 1.6%, sherwood oil 0.3%, propyl carbinol 0.2% and isooctyl alcohol 0.5% by weight percentage.

The compound method of described methanol gasoline is pressed following process implementing:

1. extract methyl alcohol by oil pump respectively by proportioning, 90# gasoline and petroleum naphtha are injected in the mixing tank, reach mixing tank volumetrical 3/4 place;

2. by proportioning Virahol, benzene mixed, sherwood oil, propyl carbinol and isooctyl alcohol are injected mixing tank successively;

3. with oil pump the solution circulated in the mixing tank was mixed 20-50 minute, make the raw material thorough mixing even;

4. the solution that filters out in the mixing tank with oil filter promptly gets high-cleaness methanol gasoline.

The invention has the beneficial effects as follows: the used gasoline per-cent of this high-cleaness methanol gasoline is no more than 50%, and proportion is low, and can and methyl alcohol is fully molten and, molten fast with speed; Need not to change vehicle any structure and component, directly the steam supply car uses, and its calorific value height, oil consumption is low, power is strong, and hydrocarbon is few in the exhaust emissions; The blending process of this high-cleaness methanol gasoline is simple, and production cost is low, can effectively save non-renewable gasoline resource.
