Abstract:

The bioliq® process developed at KIT aims at the conversion of lignocellulosic biomass into synthetic biofuels and chemicals. The process follows a two stage concept combining de-centralised pre-treatment of biomass by fast pyrolysis and centralised large scale gasification and synthesis. The process was specifically designed to convert ash rich feed materials, demanding for special design features at least in the upstream processes. The fast pyrolysis plantof the 2 MWth (500 kg/h) pilot plant at KIT was mechanically completed in 2008. In the following years, various deficiencies in the equipment were revealed. Inappropriate operating conditions and frequent failures in technical equipment made a continuous steady-state operation for several daysdifficult. After value engineering in 2013 in co-operation with Air Liquide as industrial partner, some larger modifications were implemented, improving stability of operation and relevance of results. Usually, information on the operation of larger scale equipment is scarce. Therefore, the scope of this contribution is to present the modifications performedin more detail along with their virtue and appropriateness.
