Innovation is the driving force behind corporate development. Under the guidance of Professor Chen Jinsong, an expert who has made outstanding contributions, thorough research was conducted on traditional conversion processes and catalysts, along with bold innovations, which led to the development of the following new processes and catalysts: First, a low-vapor-consumption conversion process using unsaturated towers for coal gasification – UGI-type coal gasification. The vapor consumption per ton of ammonia produced is comparable to or even lower than that of traditional saturated-tower processes. The CO percentage at the outlet is as follows: 0.88% per ton of ammonia; 1.56% for 370 kilograms of CO; 2.36% for 300 kilograms of CO; 3.76% for 250 kilograms of CO; 6.5% for 200 kilograms of CO; and 9.0% for 148 kilograms of CO. Second, a new process for monoalcohol conversion – a one-stage conversion process that further reduces vapor consumption, with the level of organic sulfur in the output remaining at or below 1 ppm over the long term； Based on 3000 NM3 of alcohol-water gas, CO: ~37%; CO2: ~8% ； H2: 2–50%; O2: 0.2%. Percentage of CO in the output; tons of alcohol vapor consumed: CO at 25%: 123 kilograms; CO at 22.5%: 185 kilograms; CO at 20.4%: 230 kilograms. III. Moderate-temperature hydrolysis catalyst: Compared with existing moderate-temperature hydrolysis catalysts, this one offers better performance at a lower cost; currently, its price is only around 20,000 yuan per M3. IV. Iron-chromium-based sulfur-resistant carbon monoxide conversion catalysts for high pressure, high temperature, and high water vapor ratios are suitable for the first and second stages of conversion of gas at pressures ≤5.0 MPa, temperatures of 250–550°C, a gas-to-vapor ratio ≥0.8, and an S content ≤4 g/NM3. Their performance is comparable to that of existing cobalt-molybdenum-based conversion catalysts, but their cost is much lower. V. Conversion process for calcium carbide off-gases with high CO content. Composition of calcium carbide off-gases with high CO content: CO ~75%, CO2 ~2%, O2 ~0.5%, H2 ~10%, N2 ~10%, CH4 ~2%, H2S ~10 ppm. Its conversion process has been developed to contribute to ‘energy conservation and emission reduction’.
