bioliq® (Biomass to Liquid), which is a four-stage process developed at KIT, enables the production of eco-friendly fuels from waste biomass in semi-industrial operation.
The accumulated, fast pyrolysis is first used to convert the dry residue biomass with a low energy content into an intermediate product, a crude oil-like solid that has a high-energy content. In the second step, the high-pressure entrained-flow gasifier converts the conditioned material into a synthetic gas at 1200 °C under a pressure of up to 80 bar. The synthetic gas mainly consists of carbon monoxide and hydrogen. The extreme conditions in the entrained-flow gasifier present great challenges in process control and the flexibility of downstream process stages. In the subsequent hot air cleaning, contaminants are filtered out of the raw synthetic gas. The last step involves mixing the purified synthetic gas in the catalytic process in order to produce custom fuels.
