Tackling the challenges in modelling entrained-flow gasification of low-grade feedstock

Abstract Development of a new technology for conversion of residual biomass into a liquid fuel via pyrolysis–gasification–gas cleaning–synthesis is the overall objective of the on-going bioliq ® project. The present paper gives an overview on research activities dedicated to mathematical modelling of entrained-flow gasification for conversion of biomass-based suspension fuels into a medium calorific (LCV around 15 MJ/kg) synthesis gas. The objective is to identify knowledge gaps that currently prohibit a knowledge-based mathematical description of reacting high-pressure multi-phase flows so as to model the bioliq ® gasification reactor in particular and biomass conversion in entrained flow gasifiers in general. Substantial knowledge gaps for high pressure process conditions have been identified for atomization of high viscous liquids, gasification chemistry for biomass-based fuels, radiative heat transfer as well as slag formation mechanisms. The paper proposes an interdisciplinary research approach in a holistic manner to close these gaps.
