A life cycle assessment of OME (oxymethylene ether) synthesis from biomass-derived syngas as a diesel additive
Download2017-01-01
Mahbub, Nafisa, Oyedun, Adetoyese Olajire, Kumar, Amit, Oestreich, Dorian, Arnold, Ulrich, Sauer, Jörg
The life cycle energy consumption and greenhouse gas (GHG) emission performances of forest biomass-derived oxymethylene ether (OME) synthesis used as a diesel additive are analyzed in this study. OME, a new alternative liquid fuel, has great miscibility with conventional fuels like diesel. OME...

Khan, Md. Mohib-Ul-Haque, Jain, Siddharth, Vaezi, Mahid, Kumar, Amit
Economic competitiveness is one of the key factors in making decisions towards the development of waste conversion facilities and devising a sustainable waste management strategy. The goal of this study is to develop a framework, as well as to develop and demonstrate a comprehensive...

Comparative net energy ratio analysis of steam pretreated pellet process for agricultural residues and energy crops
Download2016-01-01
Shahrukh, Hassan, Oyedun, Adetoyese Olajire, Kumar, Amit, Ghiasi, Bahman, Kumar, Linoj, Sokhansanj, Shahab
A process model was developed to determine the net energy ratio (NER) for the production of pellets from steam pretreated agricultural residue (wheat straw) and energy crops (i.e., switchgrass in this case). The NER is a ratio of the net energy output to the total net energy input from...

Energy balance and greenhouse gas emissions of production and sequestration of charcoal from agricultural residues
Download2016-01-01
Thakkar, Jignesh, Kumar, Amit, Ghatora, Sonia, Canter, Christina E.
Agricultural residues (wheat/barley/oat straw) can be used to produce charcoal, which can then be either landfilled off-site or spread on the agricultural field as a means for sequestering carbon. One centralized and five portable charcoal production technologies were explored in this paper. The...

Minimum production cost and optimum plant size are determined for pellet plants for three types of biomass feedstock – forest residue, agricultural residue, and energy crops. The life cycle cost from harvesting to the delivery of the pellets to the co-firing facility is evaluated. The cost varies...

Development of life cycle water footprints for oil sands-based transportation fuel production
Download2017-01-01
There is considerable focus on oil sands transportation fuel production. However, most studies focus on greenhouse gas emissions; there is limited work on understanding the life cycle water footprint. This study is an effort to address this gap. The main objective of this study is to develop...
