Potassium-salt-catalyzed tar reduction during pyrolysis oil gasification
RS Postma, SRA Kersten… - Industrial & Engineering …, 2016 - ACS Publications
The gasification of pinewood pyrolysis oil with potassium hydroxide dissolved was
investigated, using a potassium salt loaded char as catalyst, to screen if this would result in a
lower tar yield in the product stream. Experiments were performed at 700° C, after which the
product stream was thoroughly condensed and the gas stream was analyzed. The results
show a significant tar reduction for a fixed potassium-loaded char bed at a gas hourly space
velocity (GC1HSV) of 237 h–1. If the GC1HSV is reduced, the reduction in tar increases. A …
