TL;DR: In this article, the authors provide an overview of the principles, reactions, and applications of four fundamental thermo-chemical processes (combustion, pyrolysis, gasification, and liquefaction) for bioenergy production, as well as recent developments in these technologies.

TL;DR: In comparison to sewage sludges, SPP exhibited a greater capability for the production of HO and gases owing to its higher contents of volatiles and alkali metals, indicating a prospective utilization potential for SPP as a source of bio-energy.

TL;DR: In this article, the co-liquefaction of secondary pulp/paper-mill sludge and waste newspaper with a total solids concentration of 11.3% was investigated with and without the addition of catalysts in a 75ml Parr High-Pressure reactor at temperatures of 250-380°C for 20min.

TL;DR: In this paper, 17 heterogeneous catalysts, with combinations of four transition metals (Ni, Ru, Cu and Co) and various promoters (e.g., Na, K, Mg, or Ru) supported on different materials (γ-Al 2 O 3, ZrO 2, and activated carbon (AC)), were investigated with respect to their catalytic activity and stability for H 2 production from glucose via supercritical water gasification (SCWG).

TL;DR: This research provides a promising approach to the treatment and valorization of aqueous organic waste via SCWG in a bench-scale continuous down-flow tubular reactor with novel 0.1 RuNi/γ-Al(2)O(3) catalyst, which was not resistant to the attack of alkali and nitrogen compounds in the real waste, whereas the AC-based catalyst exhibited higher stability.
