Fuel stratification has the potential to extend the high load limits of homogeneous charge compression ignition (HCCI) combustion by improving the control over the combustion phase as well as reducing the maximum rate of pressure rise. In this work, experiments were carried out on a...

For in-cylinder fuel mixture distribution measurement, a method for designing a multi-component fuel for planar laser-induced fluorescence (PLIF) experiments is developed based on thermal gravity analysis and vapor-liquid equilibrium calculation. The goal is to create fuel that has a volatility...

Internal exhaust gas recirculation (EGR) is an effective strategy to reduce pumping loss and improve fuel economy using mixture dilution than traditional external EGR. In this paper, the internal EGR was obtained by exhaust gas trap (EGT) using the negative valve overlap (NVO) method. The...

Serious char formation caused by the repolymerization of unsaturated decomposition products is a considerable challenge for current lignin utilization. Here, a novel and efficient base-catalyzed depolymerization and in situ hydrogenolysis process for lignin decomposition and char elimination was...

This paper presents a new route for biomass derived aviation fuel synthesis by catalytic conversion in aqueous phase. Furfural with the yield of 71% was produced by acid hydrolysis of raw corncob, and hydrogenated to 2-methylfuran with obtaining the yield of 89% over Raney Ni catalyst, both of...

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...

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...

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...
