Low-temperature resistant ethyl alcohol diesel oil and method of producing the same

Abstract

The invention discloses a low-temperature resistance ethanol diesel oil which is prepared by materials of 75 to 90 percent of ethanol, 0.1 to 1 percent of naphthenic acid or sodium naphthenate or cobalt naphthenate or manganese naphthenate, 2 to 10 percent of isobutyl alcohol or butanol, 0.1 to 2 percent of acetone or cyclohexane, 0.3 to 0.5 percent of cetane number improver or amyl nitrate as well as 5 to 20 percent of triethylaluminium according to a volume percentage. Laboratory hot value detection and running experiment are carried out on the low-temperature resistance ethanol diesel oil prepared by the method and a testing unit is consigned for carrying out a physicochemical analysis experiment and an engine frame experiment. The running experiment result shows that the speed and therotation speed of the engine when using the low-temperature resistance ethanol diesel oil do not have remarkable differences with that of using the diesel oil of a contrast experiment; the physicochemical analysis experiment shows that each index of the low-temperature resistance ethanol diesel oil is better or approaches to that of commercial diesel oil; the solidifying point is less than 48 DEGC below zero; and the frame experiment result shows that the smoke degree of the demarcated rotation speed of an exhaust emission diesel engine is reduced by 22 percent; and the CO is reduced by 34.6percent. The low-temperature resistance ethanol diesel oil is used for a diesel oil engine and can remarkably reduce the exhaust contaminations of CO2 and CO.

Description

technical field [0001] The invention belongs to the field of fuel technology, and in particular relates to ethanol diesel. Background technique [0002] After hundreds of years of development, oil is gradually being depleted, and most of the existing major oil fields are either at the peak of production or have entered a period of decline. Europe, America, Brazil, Japan and other countries have already begun to study alternative energy sources as early as the 1990s to alleviate the deepening energy crisis. my country is an oil-poor country. Facing the challenge of insufficient oil resources, the output can no longer meet the growth of consumption. Vigorously developing renewable energy has become one of the major strategic measures to ensure my country's energy security. Under the guidance of macro policies, the research and application of renewable energy has also entered a stage of rapid development. Biodiesel has the characteristics of non-polluting, renewable, and good ...

Problems solved by technology

[0005] It can be seen from the above patents that since ethanol fuel itself has a low calorific value and accounts for 5%-20% in ethanol diesel, ethanol is only used as An auxiliary raw material, the proportion of 20% has reached the bottleneck stage, and ethanol diesel with ethanol as the basic raw material has not yet appeared
