Tar in an Indirect Gasifier (image) Chalmers University of Technology Share Print E-Mail Caption Biomass, converted in an 800 °C sand bed fluidised with steam inside of an indirect gasifier, yields a high calorific gas and tar as a by-product. Because tar, a complex mixture of valuable and undesired components, tends to create problems during the cooling of the gas, it is considered a showstopper for the application of gasification, and it needs to be removed, which is an expensive process. Researchers at Chalmers University of Technology have, together with their industrial partners, developed a solution that turns the once problematic by-product tar into a valuable product.
