Problems solved by technology

[0003] Light hydrocarbon is the raw material of light hydrocarbon gas, which can be made into combustion gas for heating. We commonly call it air-mixed light hydrocarbon gas. Because the purity of the raw material is not high, there are many side reactions during combustion. If the raw material is not purified Treatment will waste the utilization value of energy and cause great pollution. The existing desulfurizers have no significant effect on the desulfurization rate of light hydrocarbons.

Abstract

The invention relates to the technical field of research of light hydrocarbon raw material purification and discloses a novel desulfurizer applicable to light hydrocarbon fuel. Mica powder and kaolinare taken as a substrate for catalytic oxidation of sulfide, the microporous structure in the desulfurizer is changed after metal ion supporting, mechanical strength of the desulfurizer can be enhanced by combining zeolite with a thermoplastic elastomer, meanwhile, the specific surface area and the pore structure are increased, and a blending material with particle size as small as nanoscale is prepared at a high temperature by mixing and has a quite strong adsorption effect on sulfide. The prepared desulfurizer can remove 99.9% or more sulfur-containing substances and can take away harmful substances such as benzene, methanol and the like, and only carbon dioxide and water vapor are produced after combustion.

Description

technical field [0001] The invention belongs to the technical field of light hydrocarbon raw material purification research, and in particular relates to a novel desulfurizer suitable for light hydrocarbon fuels. Background technique [0002] "Hydrocarbons" are a series of substances composed of carbon and hydrogen mixed in different proportions. The lighter parts are called light hydrocarbons. The main component of natural gas is C1 methane, containing a small amount of C2 ethane. The main components of liquefied petroleum gas are C3 propane and C4 butane, which are gaseous at normal temperature and pressure, called gaseous light hydrocarbons. C5-C16 hydrocarbons are liquid at normal temperature and pressure, we call them liquid light hydrocarbons. The lightest part of liquid light hydrocarbons is C5 and C6, saturated C5 and C6 are the best raw materials for bubbling gas production, and the heavier part is gasoline, kerosene and diesel oil. Light hydrocarbon gas, like na...
