Ethanol produced from cellulosic biomass is examined as a large-scale transportation fuel. Desirable features include ethanol's fuel properties as well as benefits with respect to urban air quality, global climate change, balance of trade, and energy security. Energy balance, feedstock supply, and environmental impact considerations are not seen as significant barriers to the widespread use of fuel ethanol derived from cellulosic biomass. Conversion economics is the key obstacle to be overcome… Expand
Alternative transportation fuels from biomass
Currently, ethanol is produced from sugar cane in Brazil and from starch crops, primarily corn, in the United States. Technology is now emerging for biological production of ethanol fromExpand
Overview and evaluation of fuel ethanol from cellulosic biomass
▪ Abstract Ethanol is a high performance fuel in internal combustion engines. It is a liquid, which is advantageous in terms of storage, delivery, and infrastructural compatability. Ethanol burnsExpand
An Economic Assessment of Traditional and Cellulosic Ethanol Technologies
Abstract Ethanol is a clean, renewable fuel that can be produced from biomass resources in nearly every region of the United States. Today in the U.S. the majority of ethanol is produced from corn, aExpand

Large-scale fuel ethanol from lignocellulose
Ethanol produced from lignocellulose is considered as a largescale transportation fuel in the United States. Five key issues are identified and considered in relation to the status of current andExpand
Production of Feedstock Chemicals
TLDR
Renewable raw materials may be converted by biological means to feedstocks for the chemical industry, although advances may enable the use of less expensive lignocellulosic materals. Expand
Utilization of biomass in the U.S. for the production of ethanol fuel as a gasoline replacement—II Energy requirements, with emphasis on lignocellulosic conversion
Abstract Silvicultural operation is estimated to have a liquid fuel requirement of 77 gal. of 192° PR ethanol fuel (or 46 gal. of diesel fuel) per acre/yr, to produce 10 oven-dry tons per acre/yr ofExpand
Xylose fermentation
The economic impact of conversion of xylose to ethanol for a wood-to-ethanol plant was examined, and the maximum potential reduction in the price of ethanol from utilization of xylose is estimated toExpand
Ethanol fuel as an octane enhancer in the US fuel market
Abstract Ethanol from corn is an important US renewable energy source. In 1986, about 3·3 billion liters of ethanol were used, primarily as a gasoline extender. With lead phasedown, ethanol (octaneExpand
Ethanol from biomass by enzymatic hydrolysis
Enzymes are biological catalysts that generally are designed to do one job well, but to do one job only. Therefore, the enzymes that catalyze the hydrolysis of cellulose to sugar do not break downExpand
A comparative study of the enzymatic hydrolysis of acid‐pretreated white pine and mixed hardwood
TLDR
Pore size measurements reveal that the increase in pore volume following pretreatment for pine is only about one‐half the value obtained with mixed hardwood, which suggests that poreVolume is an important determinant of substrate–enzyme reactivity. Expand
Economics of short-rotation intensive culture for the production of wood energy feedstocks
We review research and evaluate the economics of short-rotation intensive culture (SRIC) for the production of wood energy feedstocks in six regions of the U.S. The economics of SRIC are evaluatedExpand
Fermentation of Cellulosic Substrates in Batch and Continuous Culture by Clostridium thermocellum
TLDR
Results indicate that fermentation parameters, with the exception of free cellulase activity, are essentially the same for pretreated mixed hardwood and Avicel under a variety of conditions. Expand
Gasohol: Does It or Doesn't It Produce Positive Net Energy?
TLDR
A detailed analysis of energy inputs and outputs is performed on grain-based gasohol, finding that it is an unambiguous energy producer since most energy inputs to the process can be supplied by nonpetroleum sources such as coal. Expand
