[ 1 ] - اثر تلفیقی پلاسمای غیرحرارتی و نانوکمپوزیت کربن فعال-اکسید روی بر حذف هیدروکربن های آلی فرار هوا
Background and aims: Regarding high emission rates of volatile organic compounds in the atmosphere by different industrial and transportation sources and their adverse effects on human health and the environment, the need to remove these chemicals from gas streams using new technologies with low energy consumption and high efficiency has been more evident. In this study, the catalytic effect of...
[ 2 ] - پالایش بخارات کلروفرم با استفاده از راکتور پلاسمای غیر حرارتی جدید (سال 1394)
Background and aims: One of the innovative technologies for air pollution control is non-thermal plasma. The dielectric barrier discharge reactor is one of the reactors that applied in non thermal plasma technology for air polluation control. In dielectric barrier discharge reactor, the distance between the electrodes for electric discharge is low and led to increasing space velocity of the pol...
