Vehicle low-carbon biodiesel

Abstract

The invention relates to a vehicle low-carbon biodiesel which uses coal methanol, butanol, octanol, oleic acid, 0# diesel and 200# solvent oil as raw materials. The preparation method comprises the following steps: firstly mixing methanol and oleic acid with octanol and butanol at room temperature under normal pressure, adding N,N'-phenylenediamine, sodium alkylsulfonate and copper naphthenate tostir evenly to inject into a preparation tank, secondly blending 200# solvent oil with 0# diesel, adding alkyl acid amide, ethylene glycol methyl ether, a mixture of chromium salt and calcium salt offatty acid, polyethylene vinyl acetate (T1804) and N,N'-bis(salicylidene)-1,2-propylene diamine, heating the obtained mixture to 55 DEG C with a fuel oil heat exchanger, injecting the mixture to the preparation tank, and using a stirred tank to stir for 1 hour to obtain the uniform low-carbon biodiesel. The vehicle biodiesel is convenient to use, the vehicle engine is not needed to modify, and the vehicle biodiesel can be used alone or mixed with vehicle diesel and biodiesel freely. The low-temperature start of fuel is good, the stability is high, the CO, HC and NOX contents of the emitted exhaust can be effectively reduced and the biodiesel of the invention is the preferred biomass vehicle fuel for energy conservation and carbon reduction now.

Description

technical field [0001] According to the energy structure characteristics of my country's "rich in coal, poor in oil, and low in gas", the present invention uses a large amount of coal and biomass energy to replace the existing traditional fossil fuel. Specifically, it is a kind of coal-based methanol, butanol, octanol, oleic acid, 0# diesel oil, 200# solvent oil as the main basic raw materials, and the low-temperature start-up, It is a low-carbon biodiesel additive independently developed for technical problems such as flash point, power, corrosion, and mutual solubility. A large number of popularization and application of this biodiesel technology can effectively promote the diversification of my country's energy; replace traditional energy with new biomass energy, replace fossil energy with renewable energy, and slow down my country's dependence on foreign crude oil; improve air quality and slow down the impact of the greenhouse effect. speed, to contribute to the realizatio...

Problems solved by technology

At present, breakthroughs have been made in the technology of biodiesel for vehicles under research at home and abroad, but some technical problems still need to be overcome, such as the low calorific value of methanol has a certain corrosiveness, the flash point of low-carbon biodiesel for vehicles is low, and it is harmful to the engine. Cylinder wear and carbon deposits, low-carbon biodiesel for vehicles is difficult to start at low temperature, poor stability, etc.
