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...

Kumar, Mayank, Oyedun, Adetoyese Olajire, Kumar, Amit
Hydrothermal processing, a thermochemical approach, is an excellent method of converting energy-rich biomass into useful products. This approach offers the advantage of handling biomass with relatively high moisture content by precluding an energy-intensive pretreatment step. Hydrothermal...

Pankratz, Stan, Oyedun, Adetoyese Olajire, Zhang, Xiaolei, Kumar, Amit
Large resources are being invested globally in algae research in the anticipation that these microorganisms will become the “silver bullets” that lead to economic bio-renewable fuels, new food sources, and a host of high value products and simultaneously mitigate rising atmospheric CO2 levels. A...

An optimized process design for oxymethylene ethers production from woody-biomass-derived syngas
Download2016-01-01
Zhang, Xiaolei, Oyedun, Adetoyese Olajire, Kumar, Amit, Oestreich, Dorian, Arnold, Ulrich, Sauer, Jorg
The conversion of biomass for the production of liquid fuels can help reduce the greenhouse gas (GHG) emissions that are predominantly generated by the combustion of fossil fuels. Oxymethylene ethers (OMEs) are a series of liquid fuel additives that can be obtained from syngas, which is produced...

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...

Integrated techno-economic and environmental assessments of sixty scenarios for co-firing biomass with coal and natural gas
Download2016-01-01
Agbor, Ezinwa, Oyedun, Adetoyese Olajire, Zhang, Xiaolei, Kumar, Amit
Displacement of fossil fuel-based power through biomass co-firing could reduce the greenhouse gas (GHG) emissions from fossil fuels. In this study, data-intensive techno-economic models were developed to evaluate different co-firing technologies as well as the configurations of these...

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 both regular and steam-pretreated pellet production from ligno-cellulosic biomass. NER is a ratio of the net energy output to the total net energy input from non-renewable energy source into the system. Scenarios were...

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...
