12.3. Types of Coal-derived Chemicals netl.doe.gov

Referring to Figure 1, syntheses of certain chemicals require high purity carbon monoxide (CO) as a feedstock. This is obtained by separation from syngas, which can be accomplished by several commercial processes: cryogenic purification, pressure swing adsorption, membrane separation, and salt solution absorption.

Coal Uses, Types, Pollution, Facts Britannica

Coal is an abundant natural resource that can be used as a source of energy, as a chemical source from which numerous synthetic compounds (e.g., dyes, oils, waxes, pharmaceuticals, and pesticides) can be derived, and in the production of coke for metallurgical processes. Coal is a major source of energy in the production of electrical power using steam generation. In addition, gasification and ...

1.Introduction. Chemical looping gasification (CLG) is a clean and efficient gasification technology that converts coal into syngas. During the CLG process, coal particles are fully gasified in a fuel reactor (FR) by the introduction of solid-state oxygen carrier (OC) particles, and the reduced OCs are then transported into an air reactor (AR) for their re-oxidation in air , , .

Coke (fuel) - Wikipedia

Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived from low ...

The processes for production of specific chemicals from coal are typically proprietary systems using specialized process systems. In the following discussion, some of the processes for important chemicals such as formaldehyde, olefins, etc. are presented. Methanol (MeOH) is of course another important primary chemical made from coal syngas; however, it is also a liquid fuel in its own right ...

Coal gasification - Wikipedia

Coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), natural gas (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 municipal lighting, before ...
