A diesel additive component and alcohol ester diesel containing the component

Abstract

The invention relates to a diesel oil adding component and alcohol ester diesel oil containing the same.The component comprises, by weight, 10-30 parts of dimethyl carbonate, 5-15 parts of propylene glycol, 10-50 parts of biomass oil and 0.02-0.2 part of ceria particles; alcohol ester diesel oil comprises, by weight, 30-60% of a diesel oil body, 10-20% of dimethyl carbonate, 5-10% of propylene glycol, 10-50% of biomass oil, 0.2-2%o of ceria particles, 0.2-2%o of corrosion inhibitor, 0.3-2%o of antioxidant and 0.5-2%o of an antiswelling agent.The alcohol ester diesel oil has better combustion characteristics than biodiesel and can well serve as fuel of a diesel engine under the condition that the engine does not need to be improved; meanwhile the diesel oil adding component and the alcohol ester diesel oil containing the same have the advantages that the production process is simple, energy conservation and environmental protection are achieved in the production process, and secondary pollution can be well avoided.

Description

technical field [0001] The invention belongs to the technical field of vehicle fuels, and in particular relates to a diesel additive component and alcohol ester diesel containing the component. Background technique [0002] As a non-renewable resource, the excessive development and use of oil, especially the extensive use of vehicle fuel, will lead to the depletion of petrochemical energy and the aggravation of environmental pollution. Under the current grim situation, biodiesel has received widespread attention as a clean and renewable energy source in recent years. Biodiesel is a series of long-chain fatty acid monoalkyl esters obtained by transesterification of animal and vegetable oils (fatty acid triglycerides) and alcohols (methanol or ethanol). It is a clean and renewable energy source that can be used in any proportion It is mixed with petrochemical diesel, and has low sulfur and aromatic content, high flash point, high cetane number, and good lubricity. It is an id...

Problems solved by technology

[0006] However, the reaction process is complicated, the use of alcohol must be excessive, and the consumption of a large amount of low-carbon alcohol will increase the production cost of biodiesel, and the subsequent process must have a corresponding alcohol recovery device, which has high energy consumption; at the same time, the process has difficulty in catalyst separation. After the reaction, the catalyst needs to be deactivated by washing with water, resulting in a large amount of waste acid and lye discharge, resulting in a high acid value of the product and serious environmental pollution; in addition, with the increase in biodiesel production, a large amount of by-product crude glycerin is produced. Because crude glycerin contains certain saponified substances, catalyst residues, methanol and other impurities, and is cheap, most of them are discarded as garbage, which not only causes waste of resources, but also further aggravates environmental pollution.

[0007] Research and development workers at home and abroad have conducted a lot of research and improvement on the defects of biodiesel production, but the methods involved have not fundamentally reduced the production cost of biodiesel, and have not played a significant role in the environmental pollution caused by the production process. Good preventive effect, resulting in no obvious economic benefits in large-scale production of biodiesel, and severely limited market competitiveness
