Introduction Table1 Percentage composition of simulated plastic waste.
Pyrolysis process diagram Carrier gas, N 2 Plastics Tube reactor Cooling water Liquid product Gas product Absorber
Product analysis - Gas product Analyzed C1-C3 by gas chromatograph porapak q column equipped with FID detector - liquid product Fractionation by distillation in 4 boiling temperature range IBP-200 0 C 201-250 0 C 251-370 0 C >370 0 C
Analysis of gasoline (IBP-200 0 C) product - Determination of Benzene Toluene and Xylene (BTX) Gas chromatograph OV101 column equipped with FID detector - Determination of Octane Number by NMR
Octane number of gasoline fraction by NMR A B CD E F
Study pyrolysis of PVC When the temperature increases, oil yield increases - When the temperature increases, oil yield increases and solid decreases. and solid decreases. - At 600 0 C solid increases due to polymerization reaction. - Hydrogen decrease the pyrolysis activity - At high temperature 600 0 C methane is selective in hydrocarbon gas hydrocarbon gas - Gasoline decreased but gas oil and residue increase when temperature was increased due to polymerization reaction.
- Benzene Toluene and Xylene (BTX) increased when temperature was increased - BTX decreased when hydrogen was carrier gas due to BTX was hydrogenated.
Study pyrolysis of PVC mix PP - All of ratio have synergistic effect. - Ratio of PP:PVC 2:1 and 3:1 showed high yield of hydrocarbon gas. - Ethane was selective in hydrocarbon gas. - Gasoline and residue yield was high when PP ratio increased. - BTX decreased at high PP ratio because alkylation reaction generated to isoparaffin.
Study effect of catalyst - NiMo/Al2O3 catalyzed hydrogenation dehydrogenation reaction. - Silica alumina catalyzed cracking reaction - NiMo/SiO2Al2O3 was bifunctional catalyst and catalyzed dehydrocyclization.
