Abstract

The invention discloses an environmentally-friendly insulating gas combined production technology and an industrial production device thereof. The combined production technology comprises the following steps: 1, carrying out a contact reaction on oxygen and HFP in a first fixed bed reactor under a catalyst condition or a catalyst-free condition; 2, mixing a gas product flowing out of the first fixed bed reactor with the HFP, allowing the gas product and the HFP to enter a second fixed bed reactor, and carrying out a contact reaction in the second fixed bed reactor under the action of a catalyst; and 3, carrying out separation on the effluent of the second fixed bed reactor to prepare a C5 product and a C4 product. Combined production of two novel environmentally-friendly insulating gases is realized from cheap raw materials comprising perfluoropropylene and oxygen at an atom economy of 80-90%, so the production cost is greatly reduced, and the discharge of three wastes in the production process is reduced.

Description

technical field [0001] The invention relates to the technical field of environmentally friendly insulating gas, in particular to an environmentally friendly insulating gas co-production process and an industrialized production device. Background technique [0002] In recent years, with the development of social economy and the growth of the world population, the extensive use of fossil fuels and human activities have caused the emission of various greenhouse gases to cause accelerated global warming, causing great ecological and environmental problems. The greenhouse effect of sulfur hexafluoride insulating gas widely used in the power industry is 23,500 times that of carbon dioxide. put forward higher requirements. Perfluoropentacarbonone (C5) and perfluorotetracarbonnitrile (C4) are regarded as successors to CF due to their good inertness, high electrical insulation, low degradation time in the atmosphere and greenhouse effect. 4 ,C 2 f 6 Subsequent new generation can ...
