Gasification is a process that partially burns materials to create syngas, which can be used as fuel for various engines. It is more efficient than combustion and can use a wide range of materials, including waste products. Proponents believe it could be a carbon neutral fuel.
Gasification is a process that can be used to turn a wide variety of substances into gases by partially burning them and reacting them with air to create a mixture of carbon monoxide and hydrogen known as syngas or synfuel. Synfuel can be used to run an assortment of engines from gas turbines that generate electricity to engines found in automobiles. Many proponents of clean and sustainable energy have promoted gasification as a process that should be considered, as it can be made carbon neutral and can use a wide range of materials as fuel.
Industrially, gasification is used to extract the maximum amount of energy from coal, especially weak coal seams. Gasification engines have also been built for personal use by technology enthusiasts, and some companies use gasification to consume waste products and at the same time power their facilities. During times of fuel shortages, gasification was also used extensively to power things like military vehicles.
The gasification process begins by exposing materials such as wood, coal, biomass, and other carbonaceous materials to high heat in a controlled oxygen environment. The limited oxygen in the gasifier allows some of the material to burn, creating carbon and carbon dioxide. The coal reacts with the carbon dioxide and steam produced during combustion to produce syngas, which can be filtered by the gasifier and sent to an engine. The char itself can be used in fertilizers, concrete compounds, and other applications.
The gasification process is more efficient than combustion, allowing people to extract more usable fuel from carbonaceous materials than they would by burning them. It’s not a completely clean process because it produces carbon dioxide and other gases during combustion, but it does use materials like biomass that have removed carbon dioxide from the atmosphere. Coal also blocks some of this carbon dioxide, and the process can be used to create various fuels with the assistance of filters and other chemical reactions.
Proponents of gasification believe it could be used as a carbon neutral fuel. It can also be environmentally friendly, allowing businesses to dispose of a wide range of waste materials, from wood chips to plastics, in order to generate fuel. Several experimental gassing vehicles have been built and can be seen on the road, demonstrating the potential applications of this technology to curious consumers.
