Dual‐Function Cosubstrates Enable Threonine Dehydrogenase‐Driven Chemoenzymatic Pyrrole Synthesis

Angewandte Chemie International Edition, EarlyView.
Classical Knorr chemistry meets contemporary biocatalysis. Threonine dehydrogenase generates aminoacetone from l‐threonine, which is directly intercepted in a chemoenzymatic Knorr pyrrole synthesis. A dual‐function β‐dicarbonyl substrate serves as both pyrrole precursor and hydride acceptor for integrated NAD+ recycling, affording substituted pyrroles ...

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.
