Ethanol from lignocellulosic biomass: a comparison between conversion technologies
The conversion of biomass into biofuels can increase fuel flexibility and reduce the related strategic vulnerability of petroleum based transportation fuel systems. Bioethanol has received considerable attention over the last years as a fuel extender or even neat liquid fuel. Lignocellulosic materials are very attractive substrates for the production of bioethanol because of their low cost and ...
متن کاملAn economic and environmental comparison of a biochemical and a thermochemical lignocellulosic ethanol conversion processes
With the world’s focus on rapidly deploying second generation biofuels technologies, there exists today a good deal of interest in how yields, economics, and environmental impacts of the various conversion processes of lignocellulosic biomass to transportation fuels compare. Although there is a good deal of information regarding these conversion processes, this information is typically very dif...
متن کاملBiochemical Processes for Generating Fuels and Commodity Chemicals from Lignocellulosic Biomass
Fuels and chemicals derived from biomass are regarded as an environmentally friendly alternative to petroleum based products. The concept of using plant material as a source for fuels and commodity chemicals has been embraced by governments to alleviate dependence on the volatile petroleum market. This trend is driven not only by economics but also by social and political factors. Global warmin...
متن کاملBiomass for thermochemical conversion: targets and challenges
Bioenergy will be one component of a suite of alternatives to fossil fuels. Effective conversion of biomass to energy will require the careful pairing of advanced conversion technologies with biomass feedstocks optimized for the purpose. Lignocellulosic biomass can be converted to useful energy products via two distinct pathways: enzymatic or thermochemical conversion. The thermochemical pathwa...
متن کاملPhenol and phenolics from lignocellulosic biomass by catalytic microwave pyrolysis.
Catalytic microwave pyrolysis of biomass using activated carbon was investigated to determine the effects of pyrolytic conditions on the yields of phenol and phenolics. The high concentrations of phenol (38.9%) and phenolics (66.9%) were obtained at the temperature of 589 K, catalyst-to-biomass ratio of 3:1 and retention time of 8 min. The increase of phenol and its derivatives compared to pyro...
