We have recently developed a single-step, low-temperature process for the catalytic production of fuels, such as hydrogen and/or alkanes, from renewable biomass-derived oxygenated hydrocarbons. This paper reviews our work in the development of this aqueous-phase reforming (APR) process to produce hydrogen or alkanes in high yields. First, the thermodynamic and kinetic considerations that form t...

Due to the depletion of petroleum and the recent shale gas revolution, the dropping of the price for light alkanes makes alkanes an attractive feedstock for the production of light alkenes and other valuable chemicals. Understanding the mechanism for the activation of C-H bonds in hydrocarbons provides fundamental insights into this process and a guideline for the optimization of catalysts used...

Though the lower n-alkanes are considered the most degradable components of crude oil, our experiments with microcosms simulating oiled beaches showed substantial depletion of fluorene, phenanthrene, dibenzothiophene, and other PAH in control treatments consisting of raw seawater cycled through the microcosms over a 30-day period. PAH was not detectable in pooled test system effluents. To resol...

Microbial treatment of swine fecal waste to generate long-chain linear alkanes after fast pyrolysis" (2010).

STUDY OBJECTIVES To evaluate volatile organic compounds (VOCs) in the breath as tumor markers in lung cancer. Alkanes and monomethylated alkanes are oxidative stress products that are excreted in the breath, the catabolism of which may be accelerated by polymorphic cytochrome p450-mixed oxidase enzymes that are induced in patients with lung cancer. DESIGN Combined case-control and cross-secti...

The study of water–hydrocarbon phase equilibria is very important for both scientific and industrial purposes. This work a thorough investigation the predictive capability SAFT-VR Mie equation state (EoS) aqueous hydrocarbon equilibria, including n-alkanes, alkenes, cycloalkanes, branched alkanes, aromatic hydrocarbons. For alkenes alkyl benzenes, induced association (solvation) with water cons...

A comparative study of 36 molecular descriptors derived from the topological distance matrix and van der Waals space is carried out within this paper. They are partitioned into 16 generalized topological distance matrix indices, 11 topological distance indices known in the literature (seven obtained from eigenvalues/eigenvectors of distance matrix), and 9 van der Waals molecular descriptors. Th...
