Transitioning from hydrogen to methane in biorefineries: A sustainable route to clean energy and chemicals [PDF]

open access: yesBiofuel Research Journal, 2023
This review discusses the sustainable transformation of low-quality hydrocarbon fuels, such as biomass-derived bio-oil, into valuable chemicals and clean fuels by introducing the concept of "methanotreating" that uses methane as a hydrogen source for the

Counterflow flame extinction of ammonia and its blends with hydrogen and C1-C3 hydrocarbons

open access: yesApplications in Energy and Combustion Science, 2022
Ammonia as a fuel offers the potential to avoid carbon emissions, but its combustion is hindered by low reactivity. Here, the extinction limits of NH3 and NH3 plus reactivity enhancers were measured in the counterflow laminar non-premixed flames.
