TL;DR: A new strategy for the preparation of functional porous carbons is developed via direct, ambient-pressure, thermal pyrolysis of task-specific ionic liquids (ILs) with synergistic use of the negligible volatility of the ILs and incorporation of the crosslinkable nitrile groups in the anions.
Abstract: A new strategy for the preparation of functional porous carbons is developed via direct, ambient-pressure, thermal pyrolysis of task-specific ionic liquids (ILs). The simple synthesis lies in the synergistic use of the negligible volatility of the ILs and incorporation of the crosslinkable nitrile groups in the anions. The resulting carbon materials at 800 C retain an extremely high content of nitrogen (up to 18 at%).

TL;DR: A review of recent developments in plastics cracking, a process developed to recycle plastic wastes into useful petrochemical materials under thermal cracking conditions, can be found in this paper, where plastic wastes can be decomposed into three fractions: gas, liquid and solid residue.
Abstract: This paper reviews recent developments in plastics cracking, a process developed to recycle plastic wastes into useful petrochemical materials Under thermal cracking conditions, plastic wastes can be decomposed into three fractions: gas, liquid and solid residue The liquid products are usually composed of higher boiling point hydrocarbons By adopting customary fluid cracking catalysts and reforming catalysts, more aromatics and naphthenes in the C6 ‐C8 range can be produced, which are valuable gasoline-range hydrocarbons More tests are, however, needed to verify the pyrolysis process in a pilot scale particularly for treatment of mixtures of bulk plastics Plastics cracking is only an elementary conversion technology; its application has to be combined with other technologies such as municipal solid waste collection, classification and pretreatment at the front end, as well as hydrocarbon distillation and purification at the back end Social, environmental and economic factors are also important in industrial implementation of the technology © 1998 Elsevier Science BV All rights reserved

TL;DR: In this paper, the performance of Ni-Fe/Al2O3 catalysts with the optimum composition was much higher than corresponding monometallic Ni and Fe catalysts in the steam reforming of tar from the pyrolysis of cedar wood.
Abstract: Catalytic performance of Ni-Fe/Al2O3 catalysts with the optimum composition was much higher than corresponding monometallic Ni and Fe catalysts in the steam reforming of tar from the pyrolysis of cedar wood. According to the catalyst characterization, the Ni-Fe alloys were formed and the Fe atoms on the alloys tend to be enriched on the surface, and it was suggested that the structure was maintained mainly during the reaction. The surface Fe atoms supply oxygen species, enhancing the reaction of tar and suppressing the coke formation. Excess Fe addition decreased the catalytic activity by decreasing the surface Ni atoms.

TL;DR: Commercial available biochars derived from waste wood are characterized for physical and chemical properties that can signify their relevant environmental applications, with the highest PAHs observed in biochar produced via fast pyrolysis and lowest among the gasification-produced biochar.
