Problems solved by technology

Although better hydrogenated coal tar is obtained, the cetane number of hydrogenated coal tar is not very high, and it cannot be directly used to replace diesel oil
However, in the prior art, there are relatively few studies on coal-based biofuels.

Abstract

The invention belongs to the technical field of fuel, and particularly relates to coal-based biofuel for a vehicle. The coal-based biofuel is prepared from the following raw materials in percentage by mass: 35 to 45 percent of fatty acid methyl ester, 10 to 15 percent of alcohol and the balance of hydrogenization coal tar; the total mass percentage is 100 percent. The coal-based biofuel for the vehicle has the advantages that the raw material matching is simple; crude oil resources are not needed; diesel oil can be replaced for hundred percent; the hexadecane number is high; the thermal value is high; the power is strong; the combustion is sufficient; the tail gas exhaust quantity is low; all technical indexes reach or exceed the national standard.

Description

technical field [0001] The invention belongs to the field of fuel technology, in particular to a coal-based biofuel for vehicles. Background technique [0002] Energy conservation and comprehensive utilization of resources is a long-term strategic policy for China's economic and social development. In the "Tenth Five-Year Plan" for saving and replacing fuel oil formulated by the state, "saving and replacing fuel oil" is regarded as a major strategic measure to solve the shortage of national oil resources, alleviate the contradiction between oil supply and demand, and ensure national economic security. Saving and replacing fuel oil will speed up the adjustment of my country's energy structure and promote the optimization of energy structure. It is also one of the effective ways to solve the outstanding problems in my country's "resource strategy", ensure national economic security, and promote sustainable economic and social development. [0003] At present, diesel engines b...
