Modification in thermal decomposition products of polymers by catalytic pyrolysis

Thermal Degradation Of High Molecular Weight Polyethylene To Obtain Low Molecular Weight Polyethylene Wax

“…There has been much work done in the area of catalyzed thermal degradation of polyethylenes [23,24,25,26,27]. Most thermal degradation reactions of polyethylene utilize catalysts in an attempt to lower the temperature or increase the rate of reaction [28,29]. In most cases zeolites or amorphous silica-alumina catalyst have been found to be the most effective for the thermal degradation of polyethylene [30,31,32,33,34].…”

Quantitative determination of gas mixture composition by gas chromatography—New approach

“…Several novel approaches involving use of computer simulations, various programs as well as other mathematical methods in the analysis of gas mixtures by GC have been reported but they do not take the air peak into account [9,10]. A new graphical method is reported here for estimating the composition of a complex gas mixture resulting from the pyrolysis of waste syringes containing approximately equal amounts of PE and PP.…”
