Biohydrogen production using corn stalk employing Bacillus licheniformis MSU AGM 2 strain

Bala-Amutha, K.; Murugesan, A.G. - In: Renewable Energy 50 (2013) C, pp. 621-627

Stalk of corn (Zea mays L.), a commonly available crop residue in tropical and subtropical countries and found in plenty. In this study, we demonstrated that the pretreated corn stalk waste could be used to produce hydrogen. The isolated Bacillus licheniformis MSU AGM 2 strain (HM214759) from...

Biodiesel production from non-edible plant oils

Banković-Ilić, Ivana B.; Stamenković, Olivera S.; … - In: Renewable and Sustainable Energy Reviews 16 (2012) 6, pp. 3621-3647

Because of biodegradability and nontoxicity biodiesel has become more attractive as alternative fuel. Biodiesel is produced mainly from vegetable oils by transesterification of triacylglycerols. From economic and social reasons, edible oils should be replaced by lower-cost and reliable...

Efficiencies of power flash cycles

Lai, Ngoc Anh; Fischer, Johann - In: Energy 44 (2012) 1, pp. 1017-1027

Power flash cycles (PFC) are a generalization of trilateral cycles (TLC) in which the compressed liquid is heated up to its boiling point and then performs a flash expansion during which it delivers power. The end point of the expansion may be in the wet vapour region (TLC) or in the dry vapour...

Working fluids for high-temperature organic Rankine cycles

Lai, Ngoc Anh; Wendland, Martin; Fischer, Johann - In: Energy 36 (2011) 1, pp. 199-211

Alkanes, aromates and linear siloxanes are considered as working fluids for high-temperature organic Rankine cycles (ORCs). Case studies are performed using the molecular based equations of state BACKONE and PC-SAFT. First, “isolated” ORC processes with maximum temperatures of 250°C and...

Comparison of trilateral cycles and organic Rankine cycles

Fischer, Johann - In: Energy 36 (2011) 10, pp. 6208-6219

A comparison of optimized trilateral cycle (TLC) - systems with water as working fluid and optimized organic Rankine cycle (ORC) – systems with pure organic working fluids is presented. The study includes the heat transfer to and from the cycles. The TLC - systems were optimized by the...

Optimal design of distillation column using three dimensional exergy analysis curves

Khoa, T.D.; Shuhaimi, M.; Hashim, H.; Panjeshahi, M.H. - In: Energy 35 (2010) 12, pp. 5309-5319

This paper presents two main contributions. Firstly, a new exergy graphical method is proposed for optimal design of distillation column with minimum exergy lost. The method is applicable to both grass-root and retrofit cases, respectively. The effect of design and operating parameters of a...
