Problems solved by technology

[0003] At present, there are many kinds of catalytic combustion aids on the market, but their effects are not ideal. The disadvantages of common catalytic combustion aids are:
[0004] 1. The use is limited, and most of them are fuels in the form of catalytic combustion-supporting organic gases. For the use of liquid polyalkane petrochemical fuels, many of them fail to achieve the expected results, and even produce side effects such as corrosion and swelling, embrittlement of equipment, etc.
[0005] 2. Common catalytic combustion aids have complex components, cumbersome preparation methods, and are difficult to control; for example, most of them are mixed and synthesized with various alcohols and hydrocarbons under the control of a certain temperature and pressure in different weight ratios, often due to improper control of synthesis parameters, resulting in The product is substandard and does not achieve the expected effect
[0006] 3. Some catalytic combustion aids can only play a combustion-supporting role, but they are not environmentally friendly, and may even increase pollution. Often due to intentional or unintentional doping of heavy metal elements, the pollution of exhaust emissions will increase after addition
[0007] Common catalysts with good effects are relatively expensive, cost-effective, and unsatisfactory economic benefits. Without policy subsidies, ordinary consumers are difficult to accept, so the general public is currently less used
