BACKGROUND Bio-jet fuels compatible with current aviation infrastructure are needed as an alternative to petroleum-based jet fuel to lower greenhouse gas emissions and reduce dependence on fossil fuels. Cradle to grave life cycle analysis is used to investigate the global warming potential and fossil fuel use of converting poplar biomass to drop-in bio-jet fuel via a novel bioconversion platfor...

Due to the feasibility of ethanol production in the United States, ethanol has become more attractive as a fuel source and a possible energy carrier within the hydrogen economy. Ethanol can be stored easily in liquid form, and can be internally pre-formed prior to usage in low temperature (200 o C – 400 o C) solid acid and polymer electrolyte membrane fuel cells. However, complete electrochemic...

Hydrogen production through steam reforming of ethanol was investigated with conventional supported nickel catalysts and a Ni-containing smectite-derived catalyst. The former is initially active, but significant catalyst deactivation occurs during the reaction due to carbon deposition. Side reactions of the decomposition of CO and CH4 are the main reason for the catalyst deactivation, and these...

Plasmatron fuel converters have been investigated for the conversion of a wide range of fuels. This paper is a series of papers describing an experimental and computational study of plasmatron methane reformers. This paper presents a model that uses limited mixing and chemical kinetics to investigate the plasma assisted reforming of natural gas. The Partially Stirred Reactor (PaSR) model from t...

One of the major advantages SOFCs is their high fuel flexibility. Next to natural gas and hydrogen, which are today's most common fuels for SOFC-systems cell-/stack-testing respectively, various other applicable as well. In literature, a number promising results show that available propane, butane, ammonia, gasoline, diesel etc. can be applied. Here, performance an anode supported cell operated...

The aim of this work was the evaluation of the catalytic steam reforming of a gaseous fuel obtained by steam biomass gasification to convert topping atmosphere residue (TAR) and CH4 and to produce pure H2 by means of a CO2 sorbent. This experimental work deals with the demonstration of the practical feasibility of such concepts, using a real woodgas obtained from fluidized bed steam gasificatio...

We have applied the method to carbon formation in C02 reforming of methane over eight transition metals, starting with a list of 164 elementary steps and published UBI-QEP calculations of their activation energies and using the MECHEM program for combinatorial pathway generation. The predicted coking pattern Fe > Ni > Ru > Rh, Ir, Pd > Cu, Pt is consistent with experimental results from the lit...

Acetic acid (HOAc) was selected as a bio-oil model compound for the steam reforming of bio-oil for hydrogen production. The influence of temperature and steam-to-carbon ratio (S/C) on the steam reforming of HOAc over hydrogen-type Zeolite Socony Mobil-5 (HZSM-5) and the catalyst with added Pd (Pd/HZSM-5) have been investigated in a fixedbed reactor. Brunauer–Emmett–Teller surface area measureme...

Steam reforming of glycerol to produce syngas or H2-enriched streams is a 12 promising route that has caught the attention of many researchers around the world. This reaction 13 is typically carried out over metal-based catalysts supported on stable materials. Herein we report 14 a study on the effect of Sn on the catalytic properties of Pt/C in the aforementioned reaction. A 15 series of Pt-Sn...
