Abstract

The invention discloses universal carbinol diesel oil the composition prescription of which is as follows: 60 to 85 portions of diesel oil, 10 to 30 portions of carbinol, 0.5 to 3.0 portions of oleic acid, 1.0 to 2.0 portions of ethyl acetate, 0.5 to 1.5 portions of sherwood oil, 0.5 to 1.2 portions of cyclopentyl-dicyclopentadienyl iron, 0.3 to 1.5 portions of isoamyl nitrite, 0.5 to 1.5 portions of normal butanol as well as 0.5 to 1.2 portions of isoamylol; the mixture ratio is volume portion. The cetane value of the product achieves 53 and the flash point thereof achieves 80 DEG C; the tail gas exhaustion can meet the requirements of Euro III Standard, thus completely solving the technical difficulties like easy carbinol-oil separation, ill low temperature cool starting and needing not to change any device to locomotives, ships and commercial diesel engine; the universal carbinol diesel oil can be directly used or mixed, is not restrained by seasons and regions; the oil saving rate can achieve 10 to 15 percent; besides, the needed materials and auxiliaries are broad in sources, is low in price and is remarkable in economic benefits. The universal carbinol diesel oil can be popularized and applied.

Description

technical field [0001] The invention relates to a general-purpose methanol diesel and belongs to the technical field of clean fuels. Background technique [0002] In the late 20th century, affected by the rise in international oil prices and the shortage of oil resource supply, there was a serious shortage of diesel oil at home and abroad, which brought great inconvenience to economic development and people's lives. In order to solve the shortage of diesel oil In order to solve the problem, the state has issued many relevant policies to encourage the development of diesel alternative energy. Since methanol has an oxygen content of 50%, it has good combustion performance, low emission pollution, and its freezing point can reach -2530°C. Therefore, it has been recognized as a promising and clean alternative fuel for internal combustion engines. However, since the diesel engine cannot directly use methanol, the diesel engine needs to be modified before it can be used, which l...
