TL;DR: In this paper, the influence of the ash content of the raw material had an enormous influence on the pyrolysis of anaerobically digested sewage sludge obtained from three different urban wastewater treatment plants was studied.

TL;DR: Results show that CO atmosphere gave the lowest liquid yield compared to highest 58.7% obtained with CH(4), and GC/MS analysis of the liquid products shows that CO and CO(2) atmospheres produced less methoxy-containing compounds and more monofunctional phenols.

TL;DR: In this article, the authors used microwave pyrolysis of palm kernel shell as the selected OPW produced a biochar with zero sulphur content and high heating value that is nearly comparable to conventional coal, thus indicating its potential as an eco-friendly solid fuel.

TL;DR: In this article, it has been shown that the NH3/HCN ratio is dependent on the heating rate of the fuel, which may result in higher NH3 ratio in the former types of reactors.

TL;DR: In this paper, commercial catalysts including zeolites (HZSM-5), fluid catalytic cracking (FCC) catalysts, transition metal catalysts (Fe/Cr), and aluminas, were successfully evaluated in a fixed bed catalytic reactor using a mixture of model compounds to simulate biomass flash pyrolysis vapors.
Abstract: Commercial catalysts, including zeolites (HZSM-5), fluid catalytic cracking (FCC) catalysts, transition metal catalysts (Fe/Cr), and aluminas, were successfully evaluated in a fixed bed catalytic reactor using a mixture of model compounds to simulate biomass flash pyrolysis vapors. Successful criteria including the stability index (SI), the water generation (WG), and the loss of organics (LO) were introduced to monitor the effect of catalysts and ascertain major changes in the obtained liquid product composition. SI being a measure of the effective carbonyls reduction after catalytic cracking reached 100% in the case of HZSM-5 catalysts, leading to the selective production of aromatic hydrocarbons. Transition metal catalysts (Fe/Cr) lead to the selective production of phenol and light phenolics. Comparable trends were obtained using solid biomass in the catalytic fixed bed reactor.
