Direct fermentation of sweet potato to produce maximal hydrogen and ethanol

Chu, Chen-Yeon; Sen, Biswarup; Lay, Chyi-How; Lin, Yi-Chun - In: Applied Energy 100 (2012) C, pp. 10-18

The feasibility of biofuels (hydrogen and ethanol) production from sweet potato without any pretreatment was evaluated using response surface methodology. Batch experiments were carried out with cow dung and anaerobic sewage sludge seeds at a temperature of 35°C, pH of 4.5–8.5 and substrate...

Development of a control-oriented model to optimise fuel consumption and NOX emissions in a DI Diesel engine

Molina, S.; Guardiola, C.; Martín, J.; … - In: Applied Energy 119 (2014) C, pp. 405-416

This paper describes a predictive NOX and consumption model, which is oriented to control and optimisation of DI Diesel engines. The model applies the Response Surface Methodology following a two-step process: firstly, the relationship between engine inputs (intake charge conditions and...

Operating condition optimization of corncob hydrothermal conversion for bio-oil production

Gan, Jing; Yuan, Wenqiao - In: Applied Energy 103 (2013) C, pp. 350-357

methodology (RSM). The four variables ranged from 280 to 340°C for temperature, 12–48min for retention time, 9–21% for biomass … solid content, and 0.76–2.25% for catalyst loading. It was found from RSM modeling that higher bio-oil yield and higher … content was found affected only by the reaction temperature and biomass solid content in the RSM model. Higher temperature and …
