Preparation and Characterization of Nanofibrous Catalysts for Environmental Applications
Soukup, Karel ; Topka, Pavel ; Hejtmánek, Vladimír ; Petráš, D. ; Šolcová, Olga
The aim of the study was focused on detailed description of the influence of the preparation of palladium and platinum catalysts supported on polymeric nanofibers based on poly(2,6-dimethyl-1,4-phenylene) oxide on their catalytic performance. The catalytic activity of the prepared electrospun catalysts was investigated by means of model reaction based on total oxidation of methanol. Nanofibrous catalyst supports were prepared by electrospinning technique, which represents currently the most using method to produce polymeric nanofibrous mats. This technique is based on the polymeric fiber elongation under the influence of the electrostatic field between two opposite charged electrodes (capillary electrode and the grounded plate).

Development of Process for Disposal of Plastic Waste Using Plasma Pyrolysis Technology and Option for Energy Recovery
Punčochář, Miroslav ; Ruj, B. ; Chatterjee, P.K.
Plasma pyrolysis is an innovative technology for transforming high calorific plastic waste into a valuable synthesis gas (syngas) by means of thermal plasma. The process developed is a drastic non-incineration thermal process, which uses extremely high temperature in an oxygen-starved environment to completely decompose input plastic waste into syngas, composed of very simple molecules viz : CO, H2 and hydrocarbons. A 20 kg/hr capacity plasma arc pyrolyser for treatment of plastic waste as well as energy recovery options from waste plastic has been indigenously designed, developed, installed and studied its performance at the Central Mechanical Engineering Research Institute (CSIR), Durgapur.
