Uhde’s Prenflo process to be part of joint R&D project BioTfueL in France

By Gerald Ondrey |

BioTfueL is a new joint project launched by five French partners and Uhde GmbH (Dortmund, Germany; www.uhde.eu). BioTfueL integrates the various technology stages of the so-called biomass-to-liquid (BTL) chain with the aim of developing and integrating all the stages of the BTL process chain and bringing them to market. This involves the drying and crushing of the biomass, torrefaction, gasification, purification of the synthesis gas and its ultimate conversion to second-generation biofuels using Fischer-Tropsch synthesis. Uhde’s contribution to the production of biofuels is mainly its proprietary Prenflo gasification process with direct quench (PDQ). The Prenflo process was selected on the basis of its flexibility in processing a wide variety of biomasses and other resources. It allows high energy efficiency and enables very pure synthesis gas to be produced. A torrefaction pre-treatment plant, which facilitates the application of biomass in the Prenflo-PDQ entrained-flow gasifier, and ensures lowest possible energy consumption, is installed to allow the use of a wide range of biomasses.   The overall budget for the BioTfueL project is 112.7 million euro. The project includes the construction and operation of two pilot…
