ConclusionConclusionss
Study pyrolysis of PVCStudy pyrolysis of PVC
- When the temperature increases, oil yield increasesWhen the temperature increases, oil yield increases and solid decreases.and solid decreases.- At - At 60060000C solid increases due to polymerization C solid increases due to polymerization reaction.reaction.- Hydrogen decrease the pyrolysis activity- Hydrogen decrease the pyrolysis activity
- At high temperature - At high temperature 60060000C methane is selective inC methane is selective in hydrocarbon gas hydrocarbon gas
- Gasoline decreased but gas oil and residue increase - Gasoline decreased but gas oil and residue increase when temperature was increased due to polymerization when temperature was increased due to polymerization reaction.reaction.
- Benzene Toluene and Xylene (BTX) increased when - Benzene Toluene and Xylene (BTX) increased when temperature was increasedtemperature was increased
- BTX decreased when hydrogen was carrier gas due to - BTX decreased when hydrogen was carrier gas due to BTX was hydrogenated.BTX was hydrogenated.

- All of ratio have synergistic effect. - All of ratio have synergistic effect.
- Ratio of PP:PVC - Ratio of PP:PVC 2:12:1 and and 3:13:1 showed high yield of showed high yield of hydrocarbon gas. hydrocarbon gas.
- Ethane was selective in hydrocarbon gas.- Ethane was selective in hydrocarbon gas.
- Gasoline and residue yield was high when PP ratio - Gasoline and residue yield was high when PP ratio increased.increased.
- BTX decreased at high PP ratio because alkylation - BTX decreased at high PP ratio because alkylation reaction generated reaction generated to isoparaffinto isoparaffin..
