چکیده

The removal of hydrogen sulfide (H2S) from synthetic waste gas was studied in a biotrickling filter (BTF) packed with crushed Lava rocks, operating with countercurrent flows of the air and liquid streams. A series of experiments were conducted to assess the performance of BTF under various operating conditions. Experiments were performed at different inlet H2S concentrations - in the range of 20-80 ppm - air volumetric rate, and liquid recirculation rate (LRR). A maximum elimination capacity of 22.5 gH2Sm-3h-1 was observed with more than 95% removal efficiency. Increase in LRR from 250 ml/min to 500 ml/min resulted in a decrease in the H2S elimination capacity.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
