Abstract

The invention relates to the field of environment-friendly auxiliaries, and particularly discloses a low-temperature combustion-supporting environment-friendly additive for natural gas and a preparation method thereof. The low-temperature combustion-supporting environment-friendly additive for natural gas comprises the following substances in parts by weight: 10-50 parts of dimethyl carbonate, 0-10 parts of methyl tert-butyl ether, 10-20 parts of methanol and 15-20 parts of dispersed catalytic particles, wherein the dispersed catalytic particles are carbon aerogel adsorbed with nanometer Pt particles. According to the low-temperature combustion-supporting environment-friendly additive for natural gas, dimethyl carbonate, methyl tert-butyl ether and methyl alcohol are selected as liquid matrixes, a carbon aerogel material adsorbed with precious metal Pt is taken as a catalytic material, the environment-friendly additive material is effectively wrapped and loaded in a boiling gas phase,and a uniform combination form is formed between the gas phase environment-friendly additive and natural gas, so a hydrogen-oxygen bond in the natural gas is opened under the effect of the environmental-friendly additive at a temperature of 80-100 DEG C; and thus, the combustion of the natural gas in an oxygen-enriched state is effectively catalyzed, and the activity of the natural gas in a low temperature environment is further improved.

Description

technical field [0001] The application relates to the field of environmental protection additives, more specifically, it relates to a natural gas low-temperature combustion-supporting environmental protection additive and a preparation method thereof. Background technique [0002] At present, natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (including oil field gas, gas field gas, mud volcanic gas, coalbed methane, and biologically generated gas, etc.). Natural gas is stored in underground porous rock formations, including oil field gas, gas field gas, coal bed methane, mud volcano gas and biologically generated gas, etc., and a small amount comes from coal seams. It is a high-quality fuel and chemical raw material. The main purpose of natural gas is as fuel, which can produce carbon black, chemicals and liquefied petroleum gas. Propane and butane produced from...
