Problem description:
What is water gas? What are its properties?
Analysis:
Water gas is the raw material gas for producing methanol, dimethyl ether and hydrogen. After purification and desulfurization, it becomes clean fuel and can be directly used for combustion in internal combustion engines. Water gas is composed of hydrogen and carbon monoxide. After combustion, it emits water and carbon dioxide, with trace amounts of CO, HC and NOX. The combustion speed is 7.5 times that of gasoline, and it has good anti-knock performance. According to foreign research and patent reports: the compression ratio can reach 12.5. The thermal efficiency is increased by 20-40%, the power is increased by 15%, and the fuel consumption is reduced by 30%. The exhaust gas purification is close to the European IV standard (these indicators need to be verified, but the effect is certain), and a trace amount of platinum catalyst can be used for purification. Compared with alcohols and ethers, it simplifies manufacturing and reduces equipment, with lower cost and investment. Compression or liquefaction is similar to hydrogen, but there is no need to remove CO, and the investment in website construction is low. The reduced cost and investment can also be used to partially compensate for the investment and cost of compression (compression is also required for alcohol ether production) or liquefaction. It does not have the toxicity, corrosion, swelling and other disadvantages of methanol.
