Transforming Carbon: The Science and Potential of Gasification
Abstract: Methanol and chemicals like urea and ammonia, which are the building blocks of many fertilizers, can be produced via the gasification process. Additionally, gasification can assist in the production of transportation fuels from biomass, coal, oil, and sands. Drying, pyrolysis, combustion, cracking, and reduction are the five distinct thermal processes that make up gasification. Drying removes moisture from the feedstock, while pyrolysis breaks down complex hydrocarbons into simpler molecules. Combustion …
