Problems solved by technology

However, due to various reasons, there was a lack of research on the comprehensive utilization of light hydrocarbons in the past, so that most of the light hydrocarbons were burned in the chimney as production waste, which not only wasted precious resources but also polluted the environment.

Abstract

The invention discloses a clean desulfurization modification method of a light hydrocarbon fuel, and belongs to the technical field of fuels. According to the modification method disclosed by the invention, the thermal efficiency of the light hydrocarbon fuel can be improved, and the contents of carbon monoxide and sulfur in a combustion waste gas are greatly reduced. As the components of the additive are all organic matters, no heavy metal residue which cannot be combusted exists, the residual liquid amount and attachments on a combustion stove can be greatly reduced at the same time, and thelight hydrocarbon fuel achieves the good effects of being cleaner and more sanitary and meeting the environment-friendly requirement. The popularization of the light hydrocarbon fuel is facilitated,civil and industrial series fuel varieties can be produced, and the pollution of the flue gas to the environment is reduced.

Description

technical field [0001] The invention belongs to the technical field of fuels, in particular to a method for clean desulfurization and modification of light hydrocarbon fuels. Background technique [0002] Light hydrocarbons come from a wide range of sources. Associated gas condensate in production processes such as oil fields, gas fields, and natural gas purification plants, top oil from refineries, light naphtha, and petroleum ether by-products from solvent oil plants are all sources of light hydrocarbon raw materials. . At present, my country's annual output of light hydrocarbons is nearly 10 million tons, which is equivalent to 1 / 6 of the national automobile gasoline consumption. Light hydrocarbons are clean fuels like natural gas. In addition to high calorific value and clean combustion emissions, compared with natural gas and L, it is liquid at room temperature, and it is more convenient and safe to transport, store, distribute and carry. However, due to various reaso...
