Abstract
The invention discloses new energy compound diesel, comprising diesel, oleic acid, and methanol as main raw materials. An appropriate cetane number synergist is added for compounding to form the new energy compound diesel. In winter, a small amount of a catalyst is used to adjust the condensation point index of the compound diesel. The 0# to -35# compound diesel can be prepared. The new energy compound diesel is characterized in that the new energy compound diesel makes full use of petroleum by-products and renewable biofuel, which is conducive to saving resources and improving the utilizationrate, and has the effect of saving energy, reducing emissions and purifying air. The new energy compound diesel has stable physical and chemical indicators, and the quality meets the national qualitystandards for diesel with the same label. The new energy compound diesel can be mixed with national standard diesel at any ratio, or can be used alone.
Description
technical field [0001] The invention belongs to the technical field of fuel oil, and more specifically relates to liquid fuel, a new energy compound diesel oil. Background technique [0002] Diesel is the fuel for compression ignition engines (i.e. diesel engines) and is one of the most consumed petroleum products. Compared with gasoline engines, diesel engines have higher thermal efficiency, higher power, lower fuel consumption and are more economical, so they are widely used. It is mainly used as the power of tractors, large vehicles, diesel locomotives, civil engineering and agricultural machinery. Diesel is a complex mixture of hydrocarbons with about 10 to 22 carbon atoms. It is mainly prepared from diesel fractions produced by crude oil distillation, catalytic cracking, hydrocracking, visbreaking, coking and other processes. Diesel is extracted from petroleum and is the most commonly used fuel in daily life. Development, the demand for diesel is increasing, and oil ...
