Granular Bed Filtration of Coal Pyrolysis Gas: Effects of Media Reactivity on Dust Removal and Products

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Granular bed filtration is a promising technology for removing dust from high‐temperature coal pyrolysis gas. In this work, the reactivity of coal pyrolysis products over ceramsite, char, ultrastable Y‐type (USY) zeolite, and quartz particles was compared.
