High-pressure catalytic and thermal cracking of polyethylene

H-ZSM-11 and Zn-ZSM-11 zeolites and their applications in the catalytic transformation of LDPE

“…It can be seen that increasing the reaction time from 20 to 60 min in the thermal degradation process results in higher yields of gaseous and liquid products in detriment of solid residues. This expected result is consistent with those reported by Mosio-Mosiewski et al [33].…”

Thermal degradation of polyethylene into fuel oil over silica–alumina by a continuous flow reactor

“…Silica-alumina [5][6][7], mesoporous materials [8][9][10], ZSM-5 and other zeolites [11][12][13][14][15], fresh and spent FCC catalysts [16][17][18] have been tested individually or in combination of mesoporous/nanoporous catalysts [19,20]. Pyrolysis was conducted in batch/semi-batch, fixed-, fluidized-or spouted-bed, or screw kiln reactors [21][22][23], at ambient or high pressures [24].…”

Plastic fuel Extraction from Various Waste Plastics

“…The process of pyrolysis cracking in high pressure hydrogen atmosphere is named as hydrocracking, which has been convert the heavy or high boiling plastic molecules into lighter or low boiling molecules. Hydrocracking of plastic material has several merits compared to pyrolysis and catalytic pyrolysis as it is produced highly saturated liquid products [25]. The saturated liquid product can be directly used as transportation fuel or energy production.…”
