Catalytic ozonation of ammonia using biomass char and wood fly ash

Chemosphere, 75(6), 739–744.

By: J. Kastner*, J. Miller*, P. Kolar* & K. Das*

author keywords: Catalytic ozonation; Ammonia; Room temperature; Wood fly ash; Biomass
MeSH headings : Ammonia / chemistry; Biomass; Carbon / chemistry; Charcoal / chemistry; Coal Ash; Ozone / chemistry; Particulate Matter / chemistry; Temperature
topics (OpenAlex): Catalytic Processes in Materials Science; Advanced oxidation water treatment; Environmental remediation with nanomaterials
TL;DR: Overall oxidation rates using the crude catalysts were lower than commercial catalysts, but the catalytic ozonation process operated at significantly lower temperatures and Nitric oxide was not detected and the percentage of NO(2) formed from NH(3) oxidation ranged from 0.3% to 3% (v/v).
