[ 1 ] - Hydrothermal Production of Highly Pure Nano Pyrite in a Stirred Reactor
In this study, pyrite was produced by hydrothermal precipitation from the reaction between FeSO4 and Na2S2O3 at high pressure and high temperature in a stirred reactor. The solid product was purified by means of solvent extraction to remove sulfur. Powder was characterized by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and thermal ...
[ 2 ] - Hydrogen production via steam reforming of LPG on Ni/Zeolite catalysts
Steam reforming is one of the most important processes for producing hydrogen from hydrocarbon fuels such as LPG and has attracted much attention due to its high efficiency and economy. In this study, the LPG steam reforming reaction was investigated on nickel catalysts supported on four various zeolites (H-Y, Na-Y, HZSM5 and Ferrierite). The catalytic tests were performed in a tubular fixed be...
[ 3 ] - تولید پلی ایزو بوتیلن با گرید نظامی
In this research, Polyisobutylene was produced via batch direct polymerization of isobutylene in a 1 liter reactor at low temperature. Various catalytic systems were investigated to produce desired polymer. The results showed that AlCl3 /TiCl4 catalytic system is the best catalytic system to produce desired Polyisobutylene. In addition, effects of other important parameters such as temperatur...
[ 4 ] - تولید سوخت پیشرانه جت با استفاده از ریفرمینگ کاتالیستی کروسین
In this research, the catalytic reforming of kerosene was performed to investigate the production of jet fuels with military application. For this purpose, at first the role of catalysts in the process of jet fuel production was surveyed. Then, two catalysts of Ni supported on Al2O3 and Ni/ZSM-5 was applied as a case study in a fixed bed reactor. The applied catalysts in this research were prep...
