Abstract Sour water contains ammonia, carbon dioxide, and hydrogen sulfides, producing from oil refining, coking, and coal gasification. To reduce the energy consumption in sour water stripping, a novel process is proposed which integrates with the bottom flashing mechanical vapor recompression heat pump (MVRHP) for treating such wastewater. Here, Aspen Plus™ as a powerful set of chemical process simulation software is utilized to investigate the economy and feasibility of the novel process. Com...

Abstract Low-temperature selective catalytic reduction of NOx combined with dust removal technique due to its energy conservation characteristic has been attracted much attention for fume purification. In this work, the MnOx wrapped PTFE membrane with efficient dust removal and low-temperature NH3-SCR has been prepared with a facile route. MnOx with different crystal structure were uniformly grown around the PTFE fibrils through water bath. The flower-sphere-like MnOx@PTFE(O-MnOx@PTFE) and lamel...

Abstract Polymer-grafted ion exchange adsorbents was of great interest for the development of high-performance protein chromatography in biopharmaceutical and related fields. In this work, protein retention was systematically investigated in ion exchange chromatography packed respectively with dextran-grafted cation exchange adsorbents containing sulphopropyl (SP) ligand, SP Sepharose XL and Capto S, and non-grafted cation exchange adsorbent, SP Sepharose FF, using five proteins. With an increas...

Abstract Design and synthesis of low cost and efficacious industrial catalyst for the oxidation of styrene has been an important research project. Herein, ZSM-5 zeolite containing tetrahedral vanadium (V) and Bronsted acid sites (V-H-ZSM-5) was prepared, and identified by characterizations such as XRD, SEM, UV–vis, NH3-TPD, H2-TPR N2-adsorption/desorption and FTIR. V-H-ZSM-5 performed extremely enhanced catalytic activity for the oxidation of styrene with 30% H2O2 at 40 °C. Moreover, in-situ FTI...

Abstract The generation of reliable experimental data in any experimental scale requires proper procedures not only for the reaction step but also for the feed preparation, separation, and characterization of products as well as calculations of conversion and product yields. Batch reactor is the most used experimental setup for carrying out exploratory studies for catalyst screening and development. This review is focused on describing and discussing a step-by-step methodology for conducting exp...

Abstract Gas hydrates have endowed with great potential in gas storage and rapid formation of gas hydrates is critical to use this novel technology. This work evaluated the natural gas hydrate formation process, which was compared from six parameters, including conversion of water to hydrate, storage capacity, the rate of hydrate formation, space velocity (SV) of hydrate reaction, energy consumption and hydrate removal. The literature was selected by analyzing and comparing these six parameters ...

Abstract This work is aimed at optimizing a settler structure in a mixer-settler. Two different aspects have been considered. Firstly, the flow characteristics of a settler have been examined by computational fluid dynamics (CFD) simulation with various agitation speeds of the mixer, as well as organic phase volume fractions ranging from 0.075 to 0.6. The aqueous and organic phase turbulent flow fields were measured by particle image velocimetry (PIV) technique to verify the CFD simulation. Two ...

Abstract In this paper, a model of activated carbon was established by molecular simulation and the separation performance of N2 and CH4 on activated carbon was studied. In order to evaluate the adsorption selectivity and diffusion selectivity of N2 and CH4, Grand Canonical Monte Carlo and molecular dynamic methods were used to obtain equilibrium adsorption isotherms and mean square displacements of N2 and CH4 on activated carbon with different pore sizes. Research results showed that the differ...

Abstract Metallic-monolith catalyst support with self-growing porous anodic alumina (PAA) film was prepared by anodizing Al plate. The effect of hydrothermal treatment (HTT) on the crystalline state and textural properties of PAA film was investigated by XRD, BET, SEM and TG. The HTT treatment above 50 °C and the subsequent calcination above 300 °C could convert the amorphous skeleton alumina into γ-alumina and increase the specific surface area (SBET). However, SEM images showed the HTT modific...

Abstract Polybenzimidazole (PBI) is a kind of proton transport membrane material, and its ion conductivity is a key factor affecting its application in vanadium redox flow batteries (VRFBs). The casting solvent of PBI has a significant influence on the acid doping level of PBI membranes which is closely related to ionic conductivity. In this paper, 3,3′-diaminobenzidine (DABz) and 4,4′-Dicarboxydiphenylether (DCDPE) were used as raw materials by solution condensation to prepare the PBI with ethe...
