The 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 ...
In industrial chemistry, coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), methane (CH 4), and water vapour (H 2 O)—from coal and water, air and/or oxygen.. Historically, coal was gasified to produce coal gas, also known as "town gas".Coal gas is combustible and was used for heating and ...

(COG) produced by coal gasification. Based on the use of coal in the BFBOF route and NG in the case of the DREAF route, the DREAF route emits
The Verkehrsgesellschaft Frankfurt am Main or Frankfurt Transport Authority (VGF) is Frankfurt's main public transport operator. Over 350 rail vehicles provide comprehensive mobility on nine Metro and ten tram lines. The VGF is responsible for the network's infrastructure, security, cleanliness, maintenance and customer service.
Steam/coke ratio is an essential parameter in the gasification process to improve the quality of gasification gas (used in the DRI process), and further affects the. Conclusions. A system of lowrank coal pyrolysis coupled with gasification on the basis of pilot test to hydrogenrich gas for direct reduced iron was proposed and modeled.
Finding the right technology for coal gasification for Indian coal has been a challenge. Jindal Steel and Power Ltd (JSPL), in its Angul plant, is successfully running a gasification project based on fixed bed technology for steelmaking under the DRI route and is planning to increase its capacity.
The Blast Furnace came up in a record time of 27 months, establishing new benchmarks in global steelmaking. The Integrated Steel Plant, initially envisaged as the country's first steel plant to be based on purely swadeshi raw material, involved setting up world's largest Coal Gasification Plant (CGP) for Steelmaking through the DRI route.
Airblown plants are less amenable to chemicals production applications and to high levels of precombustion CO 2 capture than oxygenblown gasifiers; 2. a gasification plant—for converting solid or liquid hydrocarbon fuels into synthesis gas (syngas); 3. a syngas gas cleanup system; and. 4. a combinedcycle power plant.
Based on the result of the work, the proposed biosyngas DRI route has comparable energy demand compared to other DRI routes, such as the wellestablished coal gasification and natural gas DRI route.

We are targetting an additional production runrate of million tonnes per year of steel in FY2021 through CGP and DRI route," he said in a statement. The plant was set up to ensure availability of chemical and thermal energy required to produce DRI at an affordable price to reduce the environmental impact of coal in the long run.
The flow process of CCHI system is shown in Fig. coal is firstly fed into the pyrolysis unit to gain the gasified coke and hydrogenrich pyrolysis gas (5860 vol% H 2, 2327 vol% CH 4 and 58 vol% CO) [25].Then the gasified coke together with steam and oxygen from the air separation unit (ASU) are fed into the gasification unit to further produce the gasification gas (mainly ...
