Factors affecting the formation of zeolite seed layers and the effects of seed layers on the growth of zeolite silicalite-1 membranes
Frontiers of Chemical Engineering in China - Tập 1 - Trang 172-177 - 2007
Xiongfu Zhang, Hai’ou Liu, Anjie Wang, Jinqu Wang
The present study investigates the formation of silicalite-1 seed layers on a porous carbon support of 0.5 μm pore size and α-A12O3 supports with different pore sizes (0.1 μm and 4 μm) via the slip-casting technique. The effects of support property, seed size and solvent on the formation of seed layers were investigated in detail. The growth of silicalite-1 membranes on different seeded supports b...... hiện toàn bộ
Experimental study on bubble behavior and CFD simulation of large-scale slurry bubble column reactor
Frontiers of Chemical Engineering in China - Tập 4 - Trang 515-522 - 2010
Haoyi Sun, Tao Li, Weiyong Ying, Dingye Fang
Slurry bubble column reactors (SBCR) is a three-phase fluidized reactor with outstanding advantages compared with other reactors and is difficult to scale-up due to lack of information on hydrodynamics and mass transfer over a wide range of operating conditions of commercial interest. In this paper, an experiment was conducted to investigate the bubble behavior in SBCR with a height of 5600 mm and...... hiện toàn bộ

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
Hongxia Yue, Hongmei Zhao, Longjiang Liu, Siping Wang, Qiong Ruan, Tongwen Wang
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...... hiện toàn bộ
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
Jiajing Xu, Wei Dai, Wenwen Shan, Lin Zhang, Yongjian Tang
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...... hiện toàn bộ
Study on the crystal morphology and melting behavior of isothermally crystallized composites of short carbon fiber and poly(trimethylene terephthalate)
Frontiers of Chemical Engineering in China - Tập 3 - Trang 255-264 - 2009
Mingtao Run, Hongzan Song, Yanping Hao
The spherulites of the short carbon fiber(SCF)/poly (trimethylene terephthalate) (PTT) composites formed in limited space at designed temperatures, and their melting behaviors were studied by the polarized optical microscopy, atomic force microscopy (AFM), and scanning electron microscopy (SEM), respectively. The results suggest that SCF content, isothermal crystallization temperatures, and the fi...... hiện toàn bộ
Review of SO 2− 4 /M x O y solid superacid catalysts
Frontiers of Chemical Engineering in China - Tập 3 - Trang 330-343 - 2009
Yanni Wu, Shijun Liao
Some metal oxides modified with sulfate ions form highly acidic or superacidic catalysts. SO 2− 4 /M x O y solid superacid catalysts, play a vital role in more and more fields such as organic synthesis, fine chemicals, pharmaceuticals, and means for strengthening environmental s...... hiện toàn bộ
Synthesis of methanol and ethanol over CuZnAl slurry catalyst prepared by complete liquid-phase technology
Frontiers of Chemical Engineering in China - Tập 4 - Trang 472-475 - 2010
Wei Huang, Linmei Yu, Wenhui Li, Zhili Ma
A new method, named the complete liquid-phase technology, has been applied to prepare catalysts for methanol synthesis. Its main innovative thought lies in preparing slurry catalysts directly from raw solution. Activity tests indicate that the CuZnAl slurry catalyst prepared by the new method can efficiently catalyze conversion of syngas to ethanol in a slurry reactor, while CO conversion reaches ...... hiện toàn bộ
The effect of capping with natural and modified zeolites on the release of phosphorus and organic contaminants from river sediment
Frontiers of Chemical Engineering in China - Tập 5 - Trang 308-313 - 2011
Shujuan Sun, Lei Wang, Suiliang Huang, Teng Tu, Hongwen Sun
A microcosm system that included river sediment, water and different zeolite capping materials (natural zeolite, surfactant-modified zeolite (SMZ), or aluminum modified zeolite (AMZ)) was designed to study the effect of capping on the release of phosphorus and three organic pollutants (phenol, pyridine, and pyrene) from the sediment to the overlying water over the course of three month. For the sa...... hiện toàn bộ
