Feedstocks and by-products

PRENFLO® gasification with dry dust feed is able to handle all types of coal (hard coal, lignite, anthracite) as well as petroleum coke, char and biomass (e.g. chicken litter, sewage sludge, wood). In addition to the main product (syngas), gasification produces by-products of economic value. The gasification of solids produces: Slag, fly ash and, after subsequent gas treatment, elemental sulphur or sulphuric acid. Slag, a non-leachable product, can be used in road building or to manufacture bricks while fly ash is a base product of choice for the cement industry.
