Thermal and catalytic degradation study of polyethylene and investigation the catalytic effect of X-Zeolite and Silica-Alumina on degradation kinetic
The thermal degradation of polyethylene (PE) was carried out in the absence and presence ofcatalystes X-Zeolite and Silica-Alumina at different temperatures. The optimum PE/Catalysisratio was 0.25:0.05 g/g, which produced highest degradation value. PE and PE/Catalysis werecharacterized by thermogravimetric analysis. The thermal degradation properties of polymerhave been studied by Infrared spec...
متن کاملCatalytic conversion of waste low density polyethylene into fuel oil
Waste Low density polyethylenes (LDPE) represent a source of energy and valuablechemicals, were pyrolysed catalytically in a batch reactor under atmospheric pressure. Calciumcarbide was used as a catalyst to explore its effect on pyrolysis product distribution. The effect oftemperature, amount of catalyst and time on the yields of the pyrolysed products wasinvestigated. The effect of catalyst o...

متن کاملMicrobial degradation of polyethylene glycols.
Mono-, di-, tri-, and tetraethylene glycols and polyethylene glycols (PEG) with molecular weight up to 20,000 were degraded by soil microorganisms. A strain of Pseudomonas aeruginosa able to use a PEG of average molecular weight 20,000 was isolated from soil. Washed cells oxidized mono- and tetraethylene glycols, but O2 consumption was not detectable when such cells were incubated for short per...
