Liquid environment protection fuel and its preparing method

Abstract

The liquid environment protecting fuel is prepared through mixing methanol or ethanol in 9-40 wt%, with viscosity improver 7-13 wt%, smoke and smell eliminating agent 1-3.6 wt%, cosolvent-pour point reducer 1-11.2 wt%, antioxidant 0.1-0.5 wt% and combustion improving cleaning agent 0-2 wt% via slight stirring, mixing the mixture with diesel oil in 40-77 wt% via slight stirring; and reaction at rest state for 6-12 hr. The liquid fuel has easy-to-obtain material, low cost, good mutual solubility, full combustion and less exhausted waste.

Description

technical field [0001] The present invention relates to a kind of liquid environment-friendly fuel and its preparation method, more specifically, relates to a kind of post-combustion waste obtained by adding methanol, ethanol and additives composed of solubilizing pour point depressant and viscosity modifier to diesel oil Environmentally friendly and economical fuel with low emissions. Background technique [0002] Due to the increasingly tense world energy and the increasing awareness of environmental protection, many countries in the world have begun to study the application of petroleum alternative energy, especially alcohol fuels such as methanol and ethanol, in large-scale internal combustion engines. Methanol is directly burned on gasoline engines or mixed with gasoline. The technology has entered the practical stage. The technology of single-burning methanol on the diesel engine through the method of modifying the engine has also been mastered abroad. In the method of...

Problems solved by technology

However, adding these co-solvents to diesel oil cannot solve the problem of poor miscibility between diesel oil, methanol and ethanol, and will also cause problems such as increased product prices, increased emissions of N-containing wastes, and increased environmental pollution.
