The bioliq® Entrained‐Flow Gasifier – a Module for the German Energiewende

Abstract

Das bioliq®‐Verfahren wurde am Karlsruher Institut für Technologie (KIT) zur Herstellung von synthetischen Kraftstoffen aus Restbiomasse entwickelt. Das mehrstufige Verfahren berücksichtigt sowohl die dezentrale Verfügbarkeit von Biomasse als auch die Notwendigkeit einer großtechnischen Synthese von Kraftstoffen. Der gesamte Prozess wird im Pilotmaßstab am KIT betrieben. Der Hochdruckflugstromvergaser, von Air Liquide Global E&C Solutions, wandelt die in einer Schnellpyrolyse vorbehandelte Biomasse in Synthesegas um, das in der anschließenden Synthese zur Benzinproduktion eingesetzt wird. Erste Ergebnisse der Anlage werden präsentiert.

Determination of active sites during gasification of biomass char with CO2 using temperature-programmed desorption. Part 1: Methodology & desorption spectra

“…straw) in a fast pyrolysis process is used. [2]. The slurry is fed to the gasifier via a burner, inside the reactor the liquid phase of the slurry droplets evaporates rapidly.…”

The Complex Way to Sustainability: Petroleum-Based Processes versus Biosynthetic Pathways in the Formation of C4 Chemicals from Syngas

“…The highest temperature at this process step reaches up to 1400 °C, necessary to disaggregate all organic molecules. The syngas composition obtained from a typical high temperature/high pressure gasification as realized in the bioliq plant is H 2 from 26 to 35%; CO from 27 to 39%; and CO 2 from 14 to 28% . Common contaminants encountered in the process are normally (all given in mg Nm –3 ) particles up to 100 000, tars up to 2 100 000, alkalis (Na and K) up to 1.7; ammoniac and hydrocyanic acid up to 1600; sulfur containing compounds (H 2 S, COS, CS 2 ) up to 170, and halogens up to 480 mg Nm –3 .…”

A High‐Speed Camera‐Based Measurement System for the High‐Pressure Entrained‐Flow Gasification

“…High-pressure entrained-flow gasifiers (EFGs) produce synthesis gas with high quality from fossil and biomass-based feedstocks [1]. In the bioliq process, developed at the Karlsruhe Institute of Technology (KIT) for the production of synthetic fuels from dry biomass residues, a high-pressure EFG converts a suspension fuel produced from biogenic residues in a fast pyrolysis step into a synthesis gas for the subsequent synthesis steps [2,3]. The feedstock is being extended to plastic wastebased pyrolysis oils.…”
