Improved performance of HZSM-5 for the ethylbenzene/xylene isomerization reaction under industrial operating conditions

Performance of Photovoltaics Under Actual Operating Conditions

assessment of the park- ang damage index for performance levels of rc moment resisting frames

چکیده هدف اصلی از طراحی لرزه ای تامین ایمنی جانی در هنگام وقوع زلزله و تعمیر پذیر بودن سازه خسارت دیده، پس از وقوع زلزله است. تجربه زلزله های اخیر نشان داده است که ساختمان های طراحی شده با آیین نامه های مبتنی بر نیرو از نظر محدود نمودن خسارت وارده بر سازه دقت لازم را ندارند. این امر سبب پیدایش نسل جدید آیین نامه های مبتنی بر عملکرد شده است. در این آیین نامه ها بر اساس تغییرشکل های غیرارتجاعی ...

Separation Performance of Improved PERVAPTM Membrane and Its Dependence on Operating Conditions

By using binary ethanol/water mixtures, the separation performance of two improved commercial pervaporation embranes (PERVAPTM) are presented. Separation performance data are analyzed and compared as a function of operating conditions. The effect of initial feed concentration on the separation performance and the effect of feed concentration on apparent activation energy are presented. For memb...

Development of an Improved Sub-Molten Salt Method for Production of Potassium Titanate from Ilmenite under Industrial Conditions

Preparation of Pt/Al2O3-Cl Catalyst and Investigation of Operating Variables Effects on Isomerization Reaction

A high chlorinated alumina catalyst obtained by treating Pt/γ-Al2O3 (0.25 wt. % Pt) samples with two mixtures of CCl4/N2 and CCl4/N2/H2 was tested for the hydroisomerization of C6 alkane. The conversion of n-hexane feed was diluted with hydrogen performed with different H2/HC ratios at various temperatures, liquid hourly space velocities (LHSVs) and 3MPa total pressure. The catalyst introduced ...
