The purpose of this paper is design a model for the capacity development of bioethanol refineries in Iran. Due to the variable weather condition, there is the uncertainty in the amount of raw materials, thus we suggest a deterministic programming model Based on probabilities for capacity development. The deterministic linear programming model is represented a signal period planning framework to...
Bioethanol has been introduced in large scale in Brazil, the US and some European countries and is projected to be one of the dominating renewable biofuels in the transportation sector within the coming 20 years. At present bioethanol is produced almost solely from either sugar – or starch-based raw materials (e.g, cane sugar, corn, wheat etc) often called first generation (1G) bioethanol. Howe...
The bioethanol is playing an increasingly important role in renewable energy in China. Based on the theory of circular economy, integration of different resources by polygeneration is one of the solutions to improve energy efficiency and to reduce environmental impact. In this study, three modes of bioethanol production were selected to evaluate the life cycle energy efficiency and environmenta...
The utilization of bioethanol as the alcohol source for biodiesel production is more environmentally advantageous over methanol owing to its lower toxicity, lower flammability and its sustainable supply from renewable agricultural resources. However, as the presence of water in crude bioethanol is the critical factor limiting the biodiesel production process, the energy-intensive and costly pur...
1.1 Motivation and environmental aspects The combustion of fossil fuels is responsible for 73% of carbon dioxide emissions into the atmosphere and therefore contributes significantly to global warming. Interest in the development of methods to reduce greenhouse gases has increased enormously. In order to control such emissions, many advanced technologies have been developed, which help in reduc...
We sequenced the genome of Saccharomyces cerevisiae IR-2, which is a diploid industrial strain with flocculation activity and the ability to efficiently produce bioethanol. The approximately 11.4-Mb draft genome information provides useful insights into metabolic engineering for the production of bioethanol from biomass.
We determined the genome sequence of industrial Saccharomyces cerevisiae strain NAM34-4C, which would be useful for bioethanol production. The approximately 11.5-Mb draft genome sequence of NAM34-4C will provide remarkable insights into metabolic engineering for effective production of bioethanol from biomass.
BACKGROUND Bioethanol produced from the lignocellulosic fractions of sugar cane (bagasse and leaves), i.e. second generation (2G) bioethanol, has a promising market potential as an automotive fuel; however, the process is still under investigation on pilot/demonstration scale. From a process perspective, improvements in plant design can lower the production cost, providing better profitability ...
BACKGROUND During industrial fermentation of lignocellulose residues to produce bioethanol, microorganisms are exposed to a number of factors that influence productivity. These include inhibitory compounds produced by the pre-treatment processes required to release constituent carbohydrates from biomass feed-stocks and during fermentation, exposure of the organisms to stressful conditions. In a...
Switchgrass displays an excellent potential to serve as a non-food bioenergy feedstock for bioethanol production in China due to its high potential yield on marginal lands. However, few studies have been conducted on the spatial distribution of switchgrass-based bioethanol production potential in China. This study created a land surface process model (Environmental Policy Integrated Climate GIS...
