Synthesis of ZSM-5 catalysts via microwave-assisted heating method for military jet fuel cracking into petroleum gas

chemical recycling of polycarbonate waste using conventional heating and microwave assisted method

پلی کربنات یکی از پلاستیکهای مهمی است که به صورت گسترده در تولید لوحهای فشرده، قطعات رایانه، مواد ساختمانی و غیره مورد استفاده قرار می گیرد. این پلیمر بصورت عمده از تراکم مونومر بیس فنولa (bpa) و کربنیل کلرید یا دی متیل کربنات ها بدست می آید. در سالهای اخیر بازیافت شیمیایی پلی کربنات بیشتر مورد توجه بوده است. بازیافت شیمیایی پلی کربنات برای بدست آوردن مواد اولیه آن با روشهای متفاوتی مانند تجزی...

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...

Microwave-assisted synthesis of molybdenum oxide nanoparticles

This paper focused on a simple approach for synthesis of molybdenum oxide (MoO3) nanoparticles and reports a facile route for synthesis of such nanoparticles, using microwave irradiation as a homogenous and powerful source of heating, using ethylene glycol as the solvent and heating medium. For more investigations, besides microwave heating, the obtained solutions were also treated by conventio...

Carbon/H-ZSM-5 composites as supports for bi-functional Fischer–Tropsch synthesis catalysts

Mesoporous H-ZSM-5–carbon composites, prepared via tetrapropylammonium hydroxide (TPAOH) post treatment of H-ZSM-5 followed by deposition of pyrolytic carbon, have been used as the support for the preparation of Co-based Fischer–Tropsch catalysts. The resulting catalysts display an improved performance during Fischer–Tropsch synthesis (FTS), with higher activity, higher selectivity towards C5–C...
