This paper describes an integrated surface–subsurface modeling study of the Fuxianhu Lake catchment (southwest China). Pollution threats to this important water resource have led to the need to evaluate transport pathways and the overall water balance of the catchment. Catchment inputs to the...

Cellulosic ethanol made from cellulosic biomass is a promising alternative to petroleum-based transportation fuels. Enzymatic hydrolysis is a crucial step in cellulosic ethanol production. In order to better understand the mechanisms of enzymatic hydrolysis, relationships between cellulosic...

Non-catalytic direct conversion of liquid natural gas (LNG) to syngas and ethylene using pulse discharge technology was firstly carried out under the temperature of liquid nitrogen and atmospheric pressure. The liquefaction of natural gas increased tremendously the collision frequency between...

This paper presents a simulation model for pedestrian collective behavior. It is supposed that the pedestrians make individual decisions during movement according to their wishes and interaction with other pedestrians. The follow effect, deterrent effect and rejection effect are put forth as...

Renewable energy systems are often criticized because of their intermittency and need for substantial amount of backup in terms of other energy sources or storage. The present paper proposes a method to estimate the required amount of storage backup for a mostly solar and wind system that uses...

Global warming is likely to profoundly influence future weather patterns, and one consequence of this is the likelihood of an increase in tropical cyclone intensity. The present paper presents a cost-benefit analysis of introducing significant amounts of green energy in the electricity system in...

In the present study, an integrated planning model was developed to find economically/environmentally optimized paths toward future smart electricity systems with high level penetration of intermittent renewable energy and new controllable electric devices at the supply and demand sides...

The main products of lignin degradation are phenolic compounds. It is meaningful to study the processes by which cyclohexane is produced from phenolic compounds via hydrodeoxygenation (HDO), because it could be used as fuel additives, chemical feedstock and solvent. In this work, support...

The hydrotreatment of bio-oil, which obtained from fast pyrolysis of pine sawdust, was investigated over MoNi/[gamma]-Al2O3 catalyst under mild conditions (373 K, 3 MPa hydrogen pressure). Acetic acid was taken as a model compound to investigate the effects of Mo promoter contents and...
