Lignocellulosic biomass conversion to produce biofuels has received significant attention because of the quest for a replacement for fossil fuels. Among the various thermochemical and biochemical routes, fast pyrolysis followed by catalytic hydrotreating is considered to be a promising near-term opportunity. This paper reports on experimental methods used 1) at the National Renewable Energy Lab...

Hydrothermal carbonization (HTC) is a novel thermochemical conversion process to convert lignocellulosic biomass into value-added products. In this work, two different biomass materials: corn stalk and Tamarix ramosissima were used as feedstock. HTC processes were performed at the temperature of 250 °C for 4 h, using a batch reactor system. Chemical and structural characterization of the solid ...

A number of transportation fuels can be produced from renewable resources. The major fractions of lignocellulosic biomass, cellulose and hemicellulose, can be broken down into sugars that can be fermented into ethanol. Biomass can also be gasified to a mixture of carbon monoxide and hydrogen for catalytic conversion into methanol. Algae could consume carbon dioxide from power plants and other s...

0TUse of lignocellulosic biomass as an alternative, renewable and sustainable source of energy has fulfilled part of the growing demand for energy in developed countries. Amongst various technologies applied to convert biomass wastes to biofuel and bioenergy, biomass gasification has attracted considerable attention. In this work, gasification of palm empty fruit bunch as a potential lignocellu...

Lignocellulosic feedstocks can be converted to biofuels, which can conceivably replace a large fraction of fossil fuels currently used for transformation. However, lignin, a prominent constituent of secondary cell walls, is an impediment to the conversion of cell walls to fuel: the recalcitrance problem. Biomass pretreatment for removing lignin is the most expensive step in the production of li...

Lignocellulosic biomass-derived sugars are considered nowadays to be an economically attractive carbohydrate feedstock for large-scale fermentations of bulk chemicals such as lactic acid. In the present study, corncob molasses containing a high content of xylose, which is one of the lignocellulosic biomasses and a waste by-product from xylitol production, was used for L-lactic acid production v...

Background With growing concern in obtaining clean and renewable energy, many works in bioenergy has been developed in order to obtain substantial gains for the environment. Due to the large environmental impact associated to the use of fossil fuels, ethanol production from lignocellulosic materia lhas been widely explored, aiming environmental, economic and social benefits. Lignocellulosic bio...

INTRODUCTION The efficient conversion of lignocellulosic feedstocks remains a key step in the commercialization of biofuels. One of the barriers to cost-effective conversion of lignocellulosic biomass to sugars remains the enzymatic saccharification process step. Here, we describe a novel hybrid processing approach comprising enzymatic pre-digestion with newly characterized hyperthermophilic en...

Use of ethanol as a substitute for gasoline may be an effective measure to reduce petroleum consumption and mitigate global warming. Ethanol is already used as an additive or total substitute for gasoline worldwide. In particular, quite large amounts of ethanol for fuel use are produced from corn in the USA and from sugarcane in Brazil. However, those crops are also cultivated for food consumpt...

Ethanol produced from biomass, such as corn grain or sugar cane, is a renewable fuel that helps lessen dependence on petroleum-based fossil fuels. Currently, the majority of ethanol production in the United States utilizes corn grain, which supplied about 14 billion gallons of ethanol to the market in 2012. In the near future, corn supplies for ethanol are expected to be limited due to concerns...
