Abstract

This study is focused on the catalytic pyrolysis of poly(vinyl chloride) over LaVOх nanostructured systems. LaVOх-type catalysts are synthesized by the solid-phase high-temperature interaction of the stoichiometric amounts of V2O5 and La2O3 and investigated by various physicochemical methods. The study of poly(vinyl chloride) noncatalytic pyrolysis under atmospheric pressure makes it possible to determine the onset temperature of the intense degradation and the optimum temperature of the pyrolysis of this material. It is shown that the catalytic pyrolysis with the use of LaVOх-type catalysts changes the qualitative and quantitative composition of gaseous fraction products so that the proportion of light olefins as the target product is increased while the yield of hydrogen chloride is suppressed by 50% compared with noncatalytic pyrolysis.
