Pyrolysis

TL;DR: In this paper, a number of activated carbons produced from peat, coconut shell, and by pyrolysis of hydrocarbons have been subjected to treatment with oxygen, chlorine, hydrogen or ammonia at elevated temperatures to get a representative series of catalyst supports differing in porous structure and surface chemistry (characterized by nitrogen adsorption and selective titrations).

TL;DR: In this article, the results showed that the active carbon is essentially amorphous and indicated the presence of traces of oxides of calcium and magnesium, while infrared spectroscopy showed peaks relating to hydroxyl, aliphatic, ether, aromatic and phenolic groups.

TL;DR: The pyrolytic lignin was mainly composed of phenol, phenolic compounds and oligomers of coniferyl, sinapyl and p-coumaryl alcohols and the number average molecular weight and the weightAverage molecular weight were 325 and 463 g/mol, respectively.

TL;DR: In this article, the effects of pressure and purge gas flow rate (gas phase residence time) on the heat demands of cellulose pyrolysis were investigated using a Setaram DSC in conjunction with stainless steel pressure vessels.

TL;DR: In this paper, the preparation of a composite carbon membrane for separation of gas mixtures is described, which is formed by a thin microporous carbon layer (thickness, 2μm) obtained by pyrolysis of a phenolic resin film supported over a macroporous substrate (pore size, 1μm; porosity, 30%).
