The coal gasification process usually requires two agents: an oxidation agent and a gasification agent (usually steam). The oxidation agent is oxygen but it can be delivered to the gasifier either as air or as nearly pure oxygen (perhaps 95% pure) (AlZareer et al., 2016c). ... Most research on the optimization of coal gasification has focused ...

Owing to China's unique energy structure, more than 97% of its ammonia is produced through coal gasification (Xiang and Zhou, 2018). However, the air separation system, which consumes a large amount of energy, provides pure oxygen and needs to separate CO 2 and H 2. This results in a high energy consumption in the gasification process.

Introduction. Coal gasification is a process in which coal reacts with gasification agents (, steam, O 2 /air, and CO 2) at a certain temperature and pressure to produce clean synthesis gas, which can be used as gaseous fuel or as a raw material for chemical synthesis to produce various chemical products and liquid gasification is an important way to achieve the clean and ...

Methanol is a clean fuel and an important feedstock for the petrochemical industry. Conventionally, the coaltomethanol process generates a substantial amount of CO2 emissions with a low yield of methanol. In this study, we propose the conceptual design development of coaltomethanol process using captured CO2 from the gasification plant by implying process intensification. The base case and ...

This process decouples the two steps, among them, coal pyrolysis converts the hydrogen in coal to H 2 to the maximum extent without being consumed, and char gasification causes the coke react with the water vapor in the gasification agent (C + H 2 O ↔ H 2 + CO) to generate H 2 and CO. Through cooperative matching of the two stages, hydrogen ...
