Biological methanation of hydrogen within biogas plants: A model-based feasibility study
Bensmann, A.; Hanke-Rauschenbach, R.; Heyer, R.; Kohrs, F. - In: Applied Energy 134 (2014) C, pp. 413-425
One option to utilize excess electric energy is its conversion to hydrogen and the subsequent methanation. An alternative to the classical chemical Sabatier process is the biological methanation (methanogenesis) within biogas plants. In conventional biogas plants methane and carbon dioxide is...

Effects of Organic Loading Rate on the Performance of a Pressurized Anaerobic Filter in Two-Phase Anaerobic Digestion
Chen, Yuling; Rößler, Benjamin; Zielonka, Simon; … - In: Energies 7 (2014) 2, pp. 736-750
The effect of organic loading rate (OLR) on a pressurized anaerobic filter was studied in a laboratory two-phase anaerobic digestion system. The anaerobic filter was operated successively at two working pressures (9 bar and 1.5 bar). The OLR<sub>(COD)</sub> for each pressure was increased from 5 to 17.5...

The evolution of waste into a resource: Examining innovation in technologies reusing coal combustion by-products using patent data
Park, Joo Young - In: Research Policy 43 (2014) 10, pp. 1816-1826
The reuse of waste begins with the development of new technologies for ways to use waste. Despite the critical role of innovation in waste reuse, innovation for waste reuse technologies has been largely overlooked in innovation studies. This paper presents the first patent study examining the...

Effects of coal properties on the production rate of combustion solid residue
Durgun, D.; Genc, A. - In: Energy 34 (2009) 11, pp. 1976-1979
The production rates of furnace bottom ash in a pulverized coal-fired power plant were monitored for a two-year period and its variations with respect to coal properties were analyzed. The power plant was originally designed to fire the coal sludge generated from a washing process; however, the...

Prediction of the bottom ash formed in a coal-fired power plant using artificial neural networks
Bekat, Tugce; Erdogan, Muharrem; Inal, Fikret; Genc, Ayten - In: Energy 45 (2012) 1, pp. 882-887
The amount of bottom ash formed in a pulverized coal-fired power plant was predicted by artificial neural network modeling using one-year operating data of the plant and the properties of the coals processed. The model output was defined as the ratio of amount of bottom ash produced to amount of...
