Design of an automated solar concentrator for the pyrolysis of scrap rubber

The oil and gas yields were relatively high with the highest gas yield reaching 32.8% with H-beta catalyst while TiO2 gave the same results as thermal pyrolysis without any catalyst. In the presence of zeolites, the dominant gasoline-like components in the gas were propene and cyclobutene. The TiO2 and non-catalytic experiments produced a gas containing gasoline-like products of mainly isoprene (76.4% and 88.4% respectively). As for the liquids they were composed of numerous components spread over a wide distribution of C10 to C29 hydrocarbons of naphthalene and cyclohexane/ene derivatives.
