WhatsApp: +86 18838072829The diversification of coal for its sustainable utilization in producing liquid transportation fuel is inevitable in countries with huge coal reserves. Gasification has been contemplated as one of the most promising thermochemical routes to convert coal into highquality syngas, which can be utilized to produce liquid hydrocarbons through catalytic FischerTropsch (FT) synthesis. Liquid ...
WhatsApp: +86 18838072829Coal gasification. Coal gasification involves coal reaction with air, oxygen, steam or their mixture to produce a gaseous fuel termed synthesis gas. The principal controlling properties of coal during the gasification process are its reactivity, ash and slag properties, particle size and coal caking and swelling. Coal reactivity
