The influence of surface modification of activated carbon with gaseous ammonia on
adsorption properties toward carbon dioxide (CO2) was reviewed. It was apparent from the …

Understanding of the chemical and physical processes that govern formation and
destruction of nitrogen oxides (NOx) in combustion of solid fuels continues to be a …

X-ray photoelectron spectroscopy (XPS) was used to investigate the fate of nitrogen
functional forms present in a lignite and its chars, chars derived from the model compounds …

Co-firing NH 3 in coal-fired power plants is an attractive method to accelerate the pace of
global decarbonization. However, the contradiction between achieving elevated …

The effect of pyrolysis temperature on biochar properties is more exacerbated when
combined with the presence of metallic dopants on the surface of the lignocellulosic …

Bark pellets have been pyrolyzed in a fluidized bed reactor at temperatures between 700
and 1000° C. Identified nitrogen-containing species were hydrogen cyanide (HCN) …

Biomass is relatively cleaner than coal and is the only renewable carbon resource that can
be directly converted into fuel. Biomass can significantly contribute to the world's energy …

The subject is critically reviewed. The following topics are covered: devolatilization of
nitrogen compounds from solid fuel; homogeneous gas-phase reactions; oxidation of char …

Nitrogen-containing chars were prepared by low-temperature carbonization (460° C) of
compounds containing pyrrolic, pyridinic, amino and cyano groups. The changes of …

Fast pyrolysis of a sewage sludge sample, which contains a high content of nitrogen, was
investigated to understand the effects of pyrolysis temperature and sweeping gas flow rate …
