Entrained flow gasification : experiments and balancing for design and scale-up

Santo, Ulrike; Böning, D.; Eberhard, M.; Schmid, H.; Kolb, Thomas

Abstract (englisch):
Reduction of CO2 emissions in the long-distance transport sector is still a mayor issue and will only be feasible by renewable liquid fuels in the medium term. At Karlsruhe Institute of Technology (KIT), the bioliq® process was developed which allows the production of synthetic fuels from biomass residues. It consists of several stages (fast pyrolysis, slurry production, high-pressure gasification, gas cleaning, gas conditioning and gas synthesis) and was realised between 2005 and 2013. The bioliq entrained flow gasifier (bioliq EFG) in the high-pressure gasification stage has got a fuel power of 5 MW and has been in operation since 2013. Model fuels and technical fuels with a high-ash content (e.g. pyrolysis oil slurries) can be supplied. Ash is deposited as slag on the refractory of a segmental cooling screen. The slag flows down the refractory and leaves the inner reactor through a water quench, which has also to be passed by the hot synthesis gas. The extensive measurement equipment at bioliq EFG enables a detailed modelling, balancing, characterisation and simulation of the entrained flow gasification process. The main objective is to develop robust tools based on ASPEN plus and CFD for the industrial design and scale-up. ... mehr
