Synthesis of ordered cerium-doped cubic mesoporous silica using long-chain ionic liquid as template
Frontiers of Chemical Engineering in China - Tập 2 - Trang 135-139 - 2008
The long-chain ionic liquid 1-hexadecyl-3-methylimidazolium chloride (C16mimCl) was used as a template to prepare cerium-doped MCM-48 materials in basic medium by a hydrothermal synthesis procedure. The effect of the amount of Ce salt and C16mimCl/Si on the synthesis were discussed in detail. This mesoporous material exhibits a pore architecture which is cubic Ia3d gyroid and possesses a large sur......
Monte Carlo simulation of the diffusion-limited aggregating process of particle suspension systems
Frontiers of Chemical Engineering in China - Tập 4 - Trang 270-274 - 2009
The aggregating process of particle suspension systems is a very universal phenomena and crucial for various processes both in nature and in industry. In this paper, the aggregating process was simulated with offlattice diffusion-limited cluster-cluster aggregation (DLCA) Monte Carlo programs. The self-similar fractal structures of aggregates have been clearly demonstrated by the statistical analy......
Spectrokinetics study of probable effects of diverse inorganic ions on bleaching of dye
Frontiers of Chemical Engineering in China - Tập 5 - Trang 131-138 - 2010
Toluidine blue (TB) is an important anticoagulant metachromasia molecule showing a pronounced variation in the visible spectrum due to the aggregation phenomenon and electrostatic interaction with the charged synthetic and biologic polymers. The current study describes the interactive role of diverse inorganic material ions on the bleaching of toluidine blue (tolonium chloride) (TB+) with urea in ......
CO2 and H2 selectivity properties of PDMS/PSf membrane prepared at different conditions
Frontiers of Chemical Engineering in China - Tập 5 - Trang 500-513 - 2011
The effects of different solvent/water coagulation mediums, different coagulation bath temperatures (CBT) and different coagulants on the performance, morphology and thermal stability of polysulfone membranes were investigated. The CO2/CH4, H2/CH4 and H2/N2 separation performance of the membranes were studied by gas permeation. Changing the N,N-dimethyl acetamide (DMAc)/water coagulation medium ra......
Protein microspheres for pulmonary drug delivery
Frontiers of Chemical Engineering in China - Tập 4 - Trang 82-86 - 2010
A new supercritical fluid (SCF) technique was developed for the preparation of microspheres for pulmonary drug delivery (PDD). This technique, based on the anti-solvent process, has incorporated advanced engineering design features to enable improved control of the particle formation process. Human recombinant insulin (HRI) was used as a model compound to evaluate the efficiency of this SCF proces......
Regioselective acylation of pyridoxine catalyzed by immobilized lipase in ionic liquid
Frontiers of Chemical Engineering in China - Tập 2 - Trang 301-307 - 2008
The regioselective acylation of pyridoxine catalyzed by immobilized lipase (Candida Antarctica) in 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM]PF6) has been investigated, and compared with that in acetonitrile (ACN). The acetylation of pyridoxine using acetic anhydride in [BMIM]PF6 gave comparable conversion of pyridoxine to 5-monoacetyl pyridoxine with considerably higher regioselectiv......
A review on research and development of iron-based sorbents for removal of hydrogen sulfide from hot coal gases
Frontiers of Chemical Engineering in China - Tập 4 - Trang 529-535 - 2010
In poly-generation and integrated gasification-combined cycle (IGCC) systems for clean energy conversion, it is essential to remove impurities such as sulfur species from hot coal gases prior to entering the subsequent units. This paper provides a comprehensive review on previous studies on high temperature removal of hydrogen sulfide from high temperature coal gases using iron-based sorbents. A t......
Sensitivity analysis of a methanol and power polygeneration system fueled with coke oven gas and coal gas
Frontiers of Chemical Engineering in China - Tập 4 - Trang 491-497 - 2010
The sensitivity analysis of a polygeneration energy system fueled with duo fuel of coke oven gas and coal gas is performed in the study, and the focus is put on the relations among syngas composition, conversation rate and performance. The impacts of the system configuration together with the fuel composition on the performance are investigated and discussed from the point of cascading utilization......
Kinetic model for hydroisomerization reaction of C8-aromatics
Frontiers of Chemical Engineering in China - Tập 2 - Trang 10-16 - 2008
Based on the reported reaction networks, a novel six-component hydroisomerization reaction network with a new lumped species including C8-naphthenes and C8-paraffins is proposed and a kinetic model for a commercial unit is also developed. An empirical catalyst deactivation function is incorporated into the model accounting for the loss in activity because of coke formation on the catalyst surface ......
Studies on the liquid-liquid interfacial mass transfer process using holographic interferometry
Frontiers of Chemical Engineering in China - Tập 2 - Trang 1-4 - 2008
This paper aims at the interfacial phenomena of liquid-liquid mass transfer and its characteristic. By using the real-time holographic technique, the concentration distributions on the aqueous side were obtained according to holographic diagrams of mass transfer of ethanol through the interface of oil and water at different initial concentrations. Furthermore, the concentrations near the interface......
