Analysis of thermogravimetric data of blends of polyolefins with calcium carbonate treated with Lica 12

Thermal and thermo-catalytic degradation of high-density polyethylene waste

“…Similar results have been published by Ding et al [23], who investigated the thermal and catalytic degradation of polyethylene. On the basis of their experiments the range of the hydrocarbon products was C 1 -C 27 in non-catalytic case, and C 1 -C 17 in catalytic case [13].…”

“…The coking decreases the catalyst activity due to blocking of active sites. Mainly acidic clays and zeolites (ZSM-5, mordenite, Y-zeolite, b-zeolite) were used as catalyst [5][6][7][8][9][10][11][12][13][14][15][16].…”

Kinetic Model of the Chemical and Catalytic Recycling of Waste Polyethylene into Fuels

“…TG, DTG, DSC, TG-MS, DTG-MS, etc.) is predominant [12][13][14][15][16][17]. Only a few researchers have investigated the cracking of waste polymers under continuous or semi-continuous conditions [18][19][20][21].…”

“…The commonly used approach is first-order kinetics to investigate the characteristics of degradation (Equation 9.1). In this approach at first the weight loss curve of polymers during the decomposition is determined, and overall rate constants are calculated [12,[14][15][16][22][23][24][25]. The objectives of experiments are the determination of the apparent activation energies and other reaction kinetic parameters (reaction rate, preexponential constant, etc.)…”

Effects of kaolin and maleic anhydride contents on melt elasticity and flexural behaviour of polypropylene/kaolin and unplasticised poly(vinyl chloride)/kaolin composites

“…The widespread use of polymer materials has created variety of new polymers with good performance and low cost [1]. Therefore, the production of new materials derived from polymer blends or alloys and composite materials have been extensively studied [2].…”
