Nowadays, the use for renewable resources comes as a necessity to stringent energetic consumption issues that are related both economic and energy autonomy (if possible) by using alternative sources of energy. In this context, one possible solution could be application anaerobic digestion processes, with main carrier result in production biogas. The focus present paper is analyze possibility ob...

ZnO and ZrO2 photo catalysts were synthesized by sol-gel auto combustion method. The products were characterized by X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). Structural and morphological properties of nano particles were investigated and the average crystalline size of ZnO and ZrO2 was obtained 44 and 51 nm, respectively. Also, photo catalytic degrada...

با توجه به نقش اساسی کاتالیست های اگزوز در کاهش آلودگی محیط زیست، کاتالیست های مختلفی برای این فرآیند مورد بررسی قرار گرفته است. اکسیدهای پروسکایتی بدلیل دارا بودن فعالیت کاتالیسای بالا و پایداری حرارتی بالا در دماهای بالا بیشتر مورد توجه می باشند. واکنش احتراق کاتالیستی یکی از واکنش های مهم در مبدل های کاتالیستی می باشد که بیشتر برای از بین بردن هیدروکربن ها (بخصوص متان) و منوکسید کربن کاربرد ...

In this article, the in situ Adaptive Tabulation (ISAT) procedure, originally developed for the efficient computation of homogeneous reactions in chemically reacting flows, is adapted and demonstrated for reacting flow computations with complex heterogeneous (or surface) reactions. The treatment of heterogeneous reactionswithin a reacting flow calculation requires solution of a set of nonlinear...
