Autor: Heiner Brookman, Fabian Gievers, Volker Zelinski, Jan Ohlert, Achim Loewen

Publikováno v: Energies, Vol 11, Iss 6, p 1582 (2018)

In many areas of application, the influence of hydrothermal carbonization (HTC) on the composition of organic pollutants is still unexplored. In this study, sewage sludge (SS) was carbonized and the input as well as the hydrochar were examined for th

Syntheses and Reactions of 2,5-Disulfobenzene-1-diazonium Salts: Towards Functionalized Sulfonate Metal-Organic Frameworks

Autor: Mathias S. Wickleder, Jens Christoffers, Thomas W. T. Muesmann, Jan Ohlert

Publikováno v: European Journal of Organic Chemistry. 2011:1695-1701

A preparation, separation, and purification protocol for 2-substituted 1,4-benzenedisulfonic acids by exploiting crystallization of the barium salts and their subsequent protonation with cation-exchange resin was developed. This technique was applied

Hydrothermal carbonization of biomass from landscape management - Influence of process parameters on soil properties of hydrochars

Autor: Michael Wark, Jan Jasper, Thomas Greve, Petra von Frieling, Jan Ohlert, Michael Röhrdanz, Rainer Buchwald, Tammo Rebling

Publikováno v: Journal of environmental management. 173

Besides pyrolysis the technology of hydrothermal carbonization (HTC) is tested to produce hydrochars for soil improvement. The chemical and physical properties of the hydrochars mainly depend on the feedstock and the process parameters reaction time

Publikováno v: ChemInform. 45

Single crystals of As(S2O7)(HS2O7) (I), Sb2(SO4)2(S2O7) (II), Bi2(S2O7)3 (III) are obtained from reactions of As2O3, SbCl3, and (BiO)2CO3 with oleum (65 % SO3) (evacuated glass tubes, 150 °C fo (I), 250 °C for (II) and (III), 24 h).
