Gasification. Gasification is a process that converts carbonaceous materials, such as coal, petroleum, or biomass – such as wood – into the simpler elements carbon monoxide and hydrogen by reacting the raw material at high (395F – 535F) temperatures. The gas produced by the gasification process is often referred to as Syngas or Renewable Natural Gas (RNG). Note: “Renewable” in this context does not mean carbon-free, although the entire process of using Syngas/RNG as a replacement for fossil fuels might be considered carbon-neutral. “Canadian Company Turns Trash Into Renewable Energy”. www.energyrefuge.com 6/14/11.”Biomass Gasification – A Promising Energy Option”.
