Coal gasification - Wikipedia

Underground coal gasification (UCG) is an industrial gasification process, which is carried out in non-mined coal seams. It involves injection of a gaseous oxidizing agent, usually oxygen or air, and bringing the resulting product gas to the surface through production wells drilled from the surface.

GASIFICATION AND THE MIDREX? DIRECT REDUCTION …

The basic objective of the gasification plant is to generate desirable reducing gases for the MIDREX Plant. The key parameter for being desirable is the gas quality (or reductants to oxidants ratio). Gas Quality = ( % H2 + % CO ) / ( % H2O + % CO2) The MIDREX Process requires a gas quality of at least 10 in order to efficiently produce DRI.

Jan 10, 2020· For evaluating the CO 2 emission by the palm kernel gasification system to supply heat to an AMP, the process was grouped into four parts as follows: (1) PKS production in a Crude Palm Oil (CPO) mill, (2) PKS transportation and handling, (3) electricity generation for gasification operations, and (4) producer gas combustion. The CO 2 equivalents emitted in parts 1–3 were predicted with ...

Syngas - Wikipedia

Syngas, or synthesis gas, is a fuel gas mixture consisting primarily of hydrogen, carbon monoxide, and very often some carbon dioxide.The name comes from its use as intermediates in creating synthetic natural gas (SNG) and for producing ammonia or methanol.Syngas is usually a product of coal gasification and the main application is electricity generation.
