Abstract

The invention relates to a porous composite material for generating electric arcs in microwaves and a preparation method thereof. The porous composite material comprises an inorganic porous skeleton and a carbon material loaded on the inorganic porous skeleton. The carbon material accounts for 0.001%-99% of the total mass of the porous composite material; the inorganic porous skeleton is an inorganic material with a porous structure, wherein the average pore diameter is 0.01-1000 microns and the porosity is 1%-99.99%. The porous composite material can be obtained by fully immersing the inorganic porous skeleton or an inorganic porous skeleton precursor into the carbon material and/or a carbon material precursor solution or dispersion liquid, and then heating, drying and carbonizing. The material has excellent mechanical properties, can generate electric arcs in a microwave field to quickly generate high temperature, and can be used in the fields of microwave high-temperature heating, biomass cracking, waste polymer material cracking, petrochemical cracking, carbon fiber composite material recovery, garbage treatment, VOC waste gas treatment, COD sewage treatment, high-temperature catalysis and the like.

Description

technical field [0001] The invention relates to the technical field of microwave heating, in particular to a porous composite material capable of generating arcs in microwaves and a preparation method thereof. Background technique [0002] More than 90% of chemical raw materials come from fossil energy such as petroleum, shale gas and coal. CO is produced in the non-renewable use of fossil energy 2 The development of environmentally friendly renewable energy has become one of the hot spots in the current energy field. For more sustainable economic and social development, there is an urgent need to replace fossil energy with renewable biomass energy. Among them, vegetable oil has become a research hotspot because of its low price and large-scale cultivation. From 2012 to 2013, the world produced a total of 462 million tons of major vegetable oils such as palm oil, rapeseed oil, sunflower oil and soybean oil. The rapid development of pyrolysis technology in recent years ha...
