Low-carbon denatured alcohol gasoline and application

Abstract

The invention discloses a low-carbon denatured alcohol gasoline and application. The low-carbon denatured alcohol gasoline comprises the following components in percentage by weight: 60-80% of alcohol, 5-15% of fuel ethanol and 5-26% of additive, wherein the additive is composed of the following components in percentage by weight: 45-55% of ortho-nitrotoluene, 20-37% of dimethoxymethane, 5-8% of dimethyl malenate, 0.4-.06% of corrosion inhibitor for metal and 0.4% of antiswelling inhibitor for rubber. The low-carbon denatured alcohol gasoline is added into the national standard gasoline in percentage by weight of 20-85% to be applied. The low-carbon denatured alcohol gasoline is a motor gasoline with better cleanability, lower gasoline consumption rate, larger mixing amount and lower raw material cost; the cost of the motor gasoline is obviously lowered, resource is saved, and engine emission is further improved; at the same time, the motor gasoline solves the problems of high gasoline consumption, low-temperature layering, and the like, lowers saturation vapour pressure and prevents the air blocking phenomenon.

Description

technical field [0001] The invention relates to a low-carbon denatured alcohol gasoline and its application. technical background [0002] Alcohol ether fuel is an industry encouraged by the state, and clean and low-carbon vehicle fuels are the general trend. Motor gasoline containing low-carbon alcohol will become an important auxiliary industry of new alternative energy because of its environmental protection, energy saving and economical efficiency. [0003] At present, E10 ethanol gasoline has been promoted and used in many provinces in China, which has played a role in improving the environment and saving oil resources. E10 ethanol gasoline blended with ethanol alone, its raw material anhydrous ethanol comes from grain, and a large amount of grain is used to produce ethanol, which not only wastes grain greatly, but also has high production costs, and its price is almost equal to that of gasoline. Companies give subsidies to maintain ethanol production. In the applica...

Problems solved by technology

E10 ethanol gasoline blended with ethanol alone, its raw material anhydrous ethanol comes from grain, and a large amount of grain is used to produce ethanol, which not only wastes grain greatly, but also has high production costs, and its price is almost equal to that of gasoline. Businesses give subsidies to maintain ethanol production

In the application of ethanol gasoline for several years, it is found that there are still different degrees of carbon deposits in the nozzle and engine block, and it cannot be added in a large proportion

Due to the poor low temperature resistance of methanol gasoline, it is necessary to add biomass higher alcohol, which is 2-3 times more expensive than gasoline, as a co-solvent, resulting in high deployment costs

In summer, if the saturated vapor pressure is too high, it will easily cause vapor resistance, and at the same time, it will swell and corrode the rubber seals, and the fuel consumption is also higher than that of national standard gasoline.
