Abstract

The invention discloses fuel with high cleanness, belonging to clean fuels. The clean fuel with stable quality is produced in order to solve the problem of comprehensive utilization of C4 and C5 fractions and crude aromatics in the plants and simplify the complex process of blending fuel. The clean fuel has simple production method and low production cost and digests the by-products in the plants. The fuel with high cleanness is prepared by blending methanol etherified solution, aromatics, C4-5 olefins and C4-5 alkanes. The fuel has the advantages of good inflammability, high octane number, good antiknock performance and the like, avoids air pollution caused by addition of tetraethyl lead, is the alternative fuel searched by the insiders and is a new generation fuel. The hydrocarbon, carbon monoxide and nitric oxides in the automobile exhausts are greatly reduced. The automobiles adopting the fuel can keep the engine fuel systems clean, do not produce carbon deposit and are free of mechanical wear, thus prolonging the service lives of the automobiles. The gasoline has high degree of atomization and realizes full combustion of the gas mixture, thus maximizing the power. The automobiles adopting the fuel are easy to start, have steady rotate speeds and have good acceleration performances.

Description

technical field

[0001] The present invention relates to a fuel, and more particularly, the present invention relates to a clean, environment-friendly fuel. Background technique

[0002] Fuel producers are increasingly using renewable resources for blending fuels. Of all the easily produced renewable compounds, alcohols such as methanol and ethanol are the most suitable for use in gasoline. A different method of blending ethanol is "chemical blending". In this case, the ethanol is fed into the refinery itself and covalently incorporated into the base gasoline. For example, U.S. Patent No. 5,633,416 and the like disclose a method for reacting C1-C4 alcohols with etherifiable olefins in low-grade gasoline products. For example ethanol is reacted with isobutylene to form ethyl tert-butyl ether (ETBE). Octane boosted by chemical blending.

[0003] On the other hand, a considerable amount of C4 and C5 fractions are produced in the high-temperature cracking ethylene process, a...
