there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
in the present research work, the kinetics of sunflower oil transesterification reaction in the presence of ba-sr/zsm-5 nanocatalyst which prepared using incipient wetness impregnation method was investigated. the 10wt.%ba-sr/zsm-5 (sr/ba=3/2) nanocatalyst was calcined at 600 °c for 6 h with a heating rate of 3 ºc/min. the experimental conditions were the methanol/oil 9/1molar ratio, reaction t...
Nanosheets of MFI zeolite were successfully synthesized by hydrothermal method and were properly characterized by XRD, FE-SEM, EDX-dot mapping, TEM, FT-IR, N2 adsorption/desorption, NH3-TPD, ICP-AES and TGA techniques. The characterizations of MFI zeolite nanosheets suitably confirmed well synthesized MFI nanostructure, superior specific surface area (695.96m2.g-1) and great mesopores volume. C...
The life cycle cost of a system is influenced by its maintainability. Maintainability is a design parameter, whose operational conditions can affect it significantly. Hence, the effects of these operational conditions should be quantified early in the design phase. The proportional repair model (PRM), which is developed based on the proportional hazard model (PHM), can be used to analyze mainta...
