2019年9月5日 · While the majority of fuel ethanol continues to be produced from food-based feedstocks such as corn and sugarcane, there remains great opportunity in the use of woody biomass feedstocks for ethanol. Technological advances and research into how to reduce the costs are promising.

2017年12月1日 · In this paper, we provide a comparative overview of ethanol from the representative biomasses of the three main worldwide producers: United States of America (USA), European Union (EU) and Brazil. The aspects of energy, emissions and economics were investigated and discussed, in an attempt to bring more recent data for the analyses.

Ethanol can be produced from plentiful, domestic, cellulosic biomass feedstocks such as herbaceous and woody plants, agricultural and forestry residues, and a large portion of municipal solid waste and industrial waste streams.

Biomass to Ethanol: Potential Production and Environmental Impacts Tiffany A. Groode and John B. Heywood Massachusetts Institute of Technology Abstract This study models and assesses the current and future fossil fuel consumption and greenhouse gas impacts of ethanol produced from three feedstocks; corn grain, corn stover, and switchgrass.

2022年6月1日 · Bioethanol, identified as a sustainable solution to fossil fuels, has gained significant attention with an annual global production of 29 billion tonnes. The need for pre-treatment of biomass is justified to enhance the bioethanol conversion efficiency.

process design and economic model for the biomass-to-ethanol process utilizing co-current dilute acid prehydrolysis with simultaneous saccharification (enzymatic) and co-fermentation. The process design included the core technologies being researched by the DOE: prehydrolysis,

Ethanol Feedstocks. Almost any plant-based material can be an ethanol feedstock. All plants contain sugars, and these sugars can be fermented to make ethanol in a process called "biochemical conversion."

Unlike other renewable energy sources, biomass can be converted directly into liquid fuels, called "biofuels," to help meet transportation fuel needs. The two most common types of biofuels in use today are ethanol and biodiesel, both of which represent the first generation of biofuel technology.

2021年3月1日 · Biomass is expected to be the major feedstock for ethanol production. Here is a complete process of direct conversion of biomass to ethanol.

2025年1月18日 · Ethanol from lignocellulosic biomass is produced mainly via biochemical routes. The three major steps involved are pretreatment, enzymatic hydrolysis, and fermentation. Biomass is pretreated to improve the accessibility of enzymes.
