英文摘要	In the context of "Emission peak, Carbon neutrality", high CO2 emission intensity, and low carbon utilization efficiency greatly restrict the development of the coal to methanol(CTM) process. A novel CTM process is proposed in the paper,which is near zero carbon emission by pulverized coal gasification integrated green hydrogen. In this case, the air separator and water-gas shift units can be eliminated, and acid gas removal unit also can be simplified. The key parameters are analyzed on the basis of established model of the two processes. The advantages of novel process are manifested in detail in comparison with the CTM process. The results show that the carbon utilization rate of the CTM process and the novel process are 41.50% and 95.77%, and the CO2 direct emission intensity is decreased from 1.939 to 0.035 t·(t MeOH)-1. An analysis of the impact of hydrogen prices and carbon taxes on product costs reveals that when the hydrogen price and carbon tax are 10.36 CNY·(kg H2)-1 and 223.3 CNY·(t CO2)-1, the production cost of two processes is equal. The new technology not only reduces carbon emissions from the CTM process, but also improves the on-site absorption capacity of renewable energy, which has good application prospects. © 2022, Editorial Board of CIESC Journal.
