Dry reforming of methane simultaneously achieves several sustainability goals: valorizing methane-activating carbon dioxide while producing syngas. The catalyst has an enormous influence on the process viability by controlling activity, selectivity, and stability. A with uniform-sized Ni-Fe alloy nanoparticles anchored into PrBaMn1.6Ni0.3Fe0.1O5+δ double-layered perovskite is assembled via a fa...

Supercritical carbon dioxide (SC-CO2 ) has been used for the first time as a reaction medium for the dehydration of glycerol to acrolein catalyzed by a solid acid. Unprecedented catalyst stability over 528 hours of time-on-stream was achieved and the rate of coke deposition on the zeolite catalyst was the lowest among extensive previous studies, showing potential for industrial application. Cok...

This paper provides background to the coke strength after reaction (CSR) test and gives perspective regarding changes in the cokinp coal market. It provides it sumtnary of some of the predicted relationships hctween the ash chemistry of coal, and coke properties of British Columbia coals. A brief overview iIf the ash chemistry of British Columbia coking coals is presented. The data arc used to ...

Several petroleum pitches have been prepared by thermal treatment of various petroleum-derived residues such as clarified oil, aromatic extract and pyrolysis tars. These pitches were characterized physico-chemically (softening point, coking value, QI, & TI) and instrumentally (NMR) and compared. Attempts have been made to correlate physicochemical properties of petroleum residues and pitches wi...

There are substantial barriers to the introduction of hydrogen fuel cells for transportation, including the high cost of fuel-cell systems, the current lack of a hydrogen infrastructure, and the relatively low fuel efficiency when using hydrogen produced from hydrocarbons. Here, we describe a solid oxide fuel cell that combines a catalyst layer with a conventional anode, allowing internal refor...

Abstract The chemical composition, structural and plastometric properties of different-ranked coals from Mongolia deposits were studied. non-isothermal iso-conversion Ozawa–Flynn–Wall Friedman model-free methods used to assess kinetic parameters differentiate decomposition steps. Key peculiarities the pyrolysis kinetics brown bituminous revealed discussed in terms composition properties. Brown ...

The recovery of aromatic hydrocarbons from coke oven gas is of great economic interest. Therefore experimental investigations on a promising alternative absorbent, biodiesel were carried out under industrial conditions with the aim of determining the performance and proving its applicability for the BTX-removal. For this purpose a mobile mini plant was constructed at the Berlin Institute of Tec...
