Catalytic degradation of plastic waste into petrochemicals using Ga-ZSM-5

Thermal and thermo-catalytic conversion of waste polyolefins to fuel-like mixture of hydrocarbons

“…The basic difference between the liquid products lies in the fact that the content of aromatic hydrocarbons in the liquid is definitely lower for the process carried out in the molten metal than for processes performed in other types of reactors. Many researchers (Aguado et al, 2008;Nishino et al, 2008;Scheirs and Kaminsky, 2006;Siddique et al, 2008;Walendziewski, 2005) reported that the content of aromatic hydrocarbons may be small or even very small for non-catalysed pyrolysis but in the presence of catalysts (particularly zeolites) they observed an increase in the amount of aromatic hydrocarbons in the liquid. The yields of the gas and liquid products for different thermal processes performed at similar temperatures were almost the same.…”

First Simple and Easy Process of Thermal Degrading Municipal Waste Plastics into Fuel Resource

“…Preliminary tests on the produced NSR fuel have shown that it is a mixture of various hydrocarbons having a range of carbon chain lengths for HDPE plastics to fuel C 3 to C 28 , LDPE plastics to fuel from C 3 to C 28 PP-5 plastics to fuel C 3 to C 25 and PS-6 plastics to fuel from C 6 to C 18 . The produced fuel density individually elaborated such as HDPE-2 fuel density is 0.782 g/ml, LDPE-4 fuel density is 0.771 g/ml, PP-5 fuel density is 0.759 and PS-6 fuel density is 0.916 (see table 3).…”

“…Even though, current technologies would conform the emission requirements, incineration arouses almost always public resistance and objections [6,7,8]. Some research group also worked with plastic conversion into fuel catalytic process [9][10][11][12][13][14][15][16][17][18][19][20], thermal degradation process [21][22][23][24][25][26][27][28][29][30][31][32][33] and pyrolysis process [34][35][36][37][38]. Natural State Research, Inc. (NSR) invented a unique process which easy and simple way to converted most of waste plastics into fuel resources and investigated that the reaction of experiment continues randomly without any catalyst or chemical substances.…”

The effect of silica–alumina catalysts on degradation of polyolefins by a continuous flow reactor

“…Older reports on thermal and catalytic degradation of polyolefins focused mainly on effectiveness of catalyst and degradation mechanisms [3][4][5][6][7] while the main interest in more recent researches was shifted to production of potentially valuable compounds in processes with improved conversion and selectivity [8][9][10][11][12][13] and to elaboration of kinetic models that could describe the degradation processes [14,15,11].…”
