Problems solved by technology

[0003] However, in the prior art, the octane number of biofuels to replace gasoline is not high enough, the calorific value is relatively low, and the stability is not good enough, which greatly limits the use of biofuels to replace gasoline
In addition, during the combustion process of gasoline, sulfur compounds such as sulfur dioxide will be produced, which will seriously pollute the air.

Abstract

The invention belongs to the technical field of fuel, and in particular relates to low-sulfur biofuel. The low-sulfur biofuel is prepared from the following raw materials in parts by weight: 85 to 100parts of aromatic hydrocarbon, 16 to 22 parts of diol, 5 to 10 parts of octanol, 0.2 to 0.8 part of isobutyl ether, 0.1 to 0.6 part of 2-ethylhexyl nitrate and 0.02 to 0.08 part of dimethyl carbonate. In the low-sulfur biofuel, the discharge of sulfide is far below the national standard, the octane value and the heat value are relatively high, the tail gas discharge property is remarkable, gasoline can be replaced and an engine does not need to be changed.

Description

technical field [0001] The invention belongs to the field of fuel technology, in particular to a low-sulfur biofuel. Background technique [0002] Today, with the rapid economic development, automobiles have become an indispensable product in people's lives, but some problems that follow are also becoming more and more serious, such as the massive exploitation of petroleum energy and the increasing shortage of petroleum resources, and the impact of automobile exhaust on the environment. pollution. In order to solve the problem of the depletion of petroleum energy, biofuel, as a substitute fuel for fuel oil, has become the most potential new alternative renewable energy. It has the advantages of cleanliness, safety and environmental protection, convenient use, and low cost. It is favored by enterprises and organizations in various countries. It also belongs to the bio-clean new energy that is encouraged to develop during the "Eleventh Five-Year Plan" period. [0003] Howeve...
