Description
Mašek, Buss, and colleagues reviewed in 2026 how the gas around heated biomass shapes the charcoal-like product called biochar. Biochar is made by pyrolysis, meaning heating plant matter with little oxygen. The review compares nitrogen, steam, carbon dioxide, methane, ammonia, pyrolysis gas itself, and mildly oxidative settings.
Nitrogen is the common lab choice, but other gases can build desired traits in a single step. Steam and carbon dioxide, for instance, can raise porosity, meaning the share of tiny holes that give biochar its working surface. Reactive gases can also add chemical groups that help biochar bind pollutants or feed soils. The review weighs gains against costs, safety issues, and effects on the gas and liquid products of pyrolysis. The authors close with open questions and a roadmap for smarter, cheaper biochar production.
