Biofuels (Energy)

Presented is a novel gasification application where biomass is steam-gasified and natural gas is steam-reformed simultaneously in a solar reactor. Solar-driven gasification is a proven technology, and can augment the biofuel industry as a domestic fuel source. Gasification performed in an...

The current “state-of-art” dilute acid pretreatment to produce bio-ethanol from corn stover requires severe conditions to overcome biomass recalcitrance, which, in turn, offers 70~80% xylose monomer yield and 5~7% furfural yield. However, high acid loadings and high reaction temperatures harm the...

Accidental fires in wood pellets silos happen frequently in the last five years. Experiments were carried out in this work at temperature range of 100 o C to 200 o C to study wood pellets chemical oxidation process. A self-heating model was developed to simulate the self-heating process using the...

Preparation of Mesoporous Silica-supported Palladium Catalyst for Biofuel Upgrade Ling Fei, Joshua Hill, Qianglu Lin, Yun Xu, Shuguang Deng, Hongmei Luo Department of Chemical Engineering, New Mexico State University, Las Cruces, NM 88003 A large number of reactions in organic chemistry (such as...

The pyrolytic conversion of biomass to into liquid fuels has the potential to become drop-in transportation fuels if some of its negative attributes such as high total acid number (TAN), high viscosity, and poor storage stability are overcome. We investigated nickel phosphide supported on fluid...

There are two major problems in current cellulosic ethanol production process: low ethanol productivity and high enzyme loading. Based on the current Separate Hydrolysis and Fermentation (SHF) process, it takes at least 96h to perform enzymatic hydrolysis to convert AFEX-CS to fermentable sugars at...

Abstract: Biochemical conversion is a promising route to produce fuels and chemicals from cellulosic biomass. A key step in the process is biomass liquefaction, where enzymes are used to break down pretreated cellulosic particles. During this process, drastic changes in the mechanical properties of...

Furfural is an important chemical and also a building block for production of drop-in hydrocarbon fuels and can be produced from cellulosic biomass such as woody crops and bagasse by hydrolysis and dehydration with mineral acids. However, furfural yields employing current technologies are limited...

A two-stage pyrolysis was conducted in this work. The purpose of the multiple stages is to provide a segregated product evolution in which the vapor products maybe be more selectively treated by catalysts to improve product quality and catalyst stability in comparison to one step pyrolysis in which...

Concerns about dwindling fossil fuel reserves and climate change, energy independence, and depletion of ecosystem goods and services have driven the development of alternative technologies such as biomass-based fuels (biofuels). Although biofuels may be a step towards alleviating the aforementioned...
