Abstract

The invention relates to the technical field of new material processing, and discloses a desulfurizer for improving sulfur removal efficiency in the petroleum industry. The prepared high-efficiency load-type desulfurizer is used for the purification of raw oil and gas, and desulfurization can be carried out at normal temperature. The desulfurization The agent uses mesoporous silica as the carrier to load nano-gold desulfurization active particles. It has high gas penetration efficiency, is highly dispersed, has a large capacity, has a developed internal microporous structure and chemical activity, and has a large specific surface area and strong adsorption capacity. There is no loss in desulfurization flow rate and stability after the second cycle, which improves the cycle life of the desulfurizer; the invention can significantly improve the combustion efficiency of liquid light hydrocarbons, and solve the problems of low efficiency of biological desulfurization, complicated process, and low purification amount of chemical desulfurization , poor stability and high cost, no need to invest in additional active reagents, no polluted waste liquid, no toxicity, and significantly improved economic and social benefits.

Description

Technical field [0001] The present invention belongs to the technical field of new material processing, and is specifically involved in an improved desulfurizing agent in the petroleum industry. Background technique [0002] One of the oil industry and the fuel industry. From exploration, mining to the processed oil, a series of processes were completed by the oil sector. Provide various fuel oils for the various departments of the national economy, including the exploration, mining, refining, storage and transportation of natural oil and oil shale. As an important part of energy, oil increases rapidly in my country's primary energy consumption and production and is basically stable at a certain level, and my country has also changed from the petroleum exporting country from the past to oil imported countries. [0003] During the oil extraction process, organic sulfides in the oil and gas will decompose, produce hydrogen sulfide. The gas is extremely harmful, strong toxicity, whi...
