Miscanthus : a fast - growing crop for biofuels and chemicals production
نویسندگان
چکیده
Miscanthus represents a key cand idate energy crop for use in biomass-to-liquid fuel-conversion processes and biorefi neries to produce a range of liquid fuels and chemicals; it has recently attracted considerable attention. Its yield, elemental composition, carbohydrate and lignin content and composition are of high importance to be reviewed for future biofuel production and development. Starting from Miscanthus, various pre-treatment technologies have recently been developed in the literature to break down the lignin structure, disrupt the crystalline structure of cellulose, and enhance its enzyme digestibility. These technologies included chemical, physicochemical, and biological pre-treatments. Due to its signifi cantly lower concentrations of moisture and ash, Miscanthus also represents a key candidate crop for use in biomass-to-liquid conversion processes to produce a range of liquid fuels and chemicals by thermochemical conversion. The goal of this paper is to review the current status of the technology for biofuel production from this crop within a biorefi nery context. © 2012 Society of Chemical Industry and John Wiley & Sons, Ltd

Pretreatment on Miscanthus lutarioriparious by liquid hot water for efficient ethanol production
BACKGROUND The C4 perennial grass Miscanthus giganteus has proved to be a promising bio-energy crop. However, the biomass recalcitrance is a major challenge in biofuel production. Effective pretreatment is necessary for achieving a high efficiency in converting the crop to fermentable sugars, and subsequently biofuels and other valued products. RESULTS Miscanthus lutarioriparious was pretreat...
متن کاملBioenergy crop productivity and potential climate change mitigation from marginal lands in the United States: An ecosystem modeling perspective
Growing biomass feedstocks from marginal lands is becoming an increasingly attractive choice for producing biofuel as an alternative energy to fossil fuels. Here, we used a biogeochemical model at ecosystem scale to estimate crop productivity and greenhouse gas (GHG) emissions from bioenergy crops grown on marginal lands in the United States. Two broadly tested cellulosic crops, switchgrass, an...
متن کاملThe Role that Lignocellulosic Feedstocks and Various Biorefining Technologies Can Play in Meeting Ireland’s Biofuel Targets
Modern biorefineries target the production of chemicals and fuels from lignocellulosic biomass feedstocks such as energy crops and biodegradeable wastes. Biofuels produced from such processes are considered “second-generation-biofuels” and are considered to be more sustainable than first-generation-biofuels from food and oil crops. This paper considers the contribution that biorefineries can ma...
متن کاملToward the domestication of lignocellulosic energy crops: learning from food crop domestication.
Domestication of cereal crops has provided a stable source of food for thousands of years. The extent to which lignocellulosic crops will contribute to the world's renewable energy depends largely on how the new crops will be domesticated. Growing miscanthus as biofuel feedstocks on marginal and degraded land in northern and northwestern China offers an example for developing theoretical framew...
متن کاملBioenergy crops Miscanthus x giganteus and Panicum virgatum reduce growth and survivorship of Spodoptera frugiperda (Lepidoptera: Noctuidae).
Large-scale cultivation of plants used as biofuels is likely to alter the ecological interactions of current agricultural crops and their insect pests in a myriad of ways. Recent evidence suggests many contemporary maize pests will be able to use potential biofuel crops such as switchgrass, Panicum virgatum L., and miscanthus as hosts. To determine how suitable these biofuels are to the maize, ...
