WebbGasification takes place in two main stages. First, the biomass is partially burned to form producer gas and charcoal. In the second stage, the carbon dioxide and water produced in the first stage are chemically reduced by the charcoal, forming carbon monoxide and hydrogen. Gasification requires temperatures of around 800°C or more to minimize ... WebbThe gas produced by the gasifier is often referred to as producer gas. The producer gas contains CO, CO2, H2 and H2O as well as CH4 and higher hydrocarbons, including some tar compounds. There are also small …
