KONVERSI TERMAL CAMPURAN POLIETILENA-EMPURUNG KELAPA MENJADI HIDROKARBON CAIR

Abstract

PolleVena mempakan pannier dengan rumus Vint f-CF12-CH.2-in dimana n menyattn perulangan Mukha. Sedangkan tempurung kelapa mengandung selulose sebanyak 36,3%, lignin 28,3%, dan hemiselulosa 25,1%. Dengan mentuat campuran poltlitenNtempuning kelapa dalam proses konversi termal tanpa adanya oksigen ipintsisk diharapkan polietilena dapat mentdi pensuplal Nitrogen sehingga peduk hidrokarbon [air akan meningkat. Untuk mengetahui seberapa eiektd pengaruh polietilena Hamden hidmicarbon oak yang dthasilkan, diNkukan vadasi komposisi polietilena-tempuning Malone dalam proses pirdisis dengan den tanpa katalis. Sebagei hatalis digunakan zeta alam Wonosad. Kaiaks mot alam dnual metlui 'snap: aktivasi, kalsinasi dan proses hidrotermal. Enarn puluh gram campuran polieVenstempuning kNapa dengan peubangingen 5:1, 4:2, 3:3, 2:4,1:5 gfinroimis pada temperatur 300°C [lap organik yang &basilican kemudian didinginkan Sehingga diperoleh produk pair. Uniuk proses nrolisis katatk, prosedumya sama, hanya dilakukan penembanan katalls pada ?natio. Produk cair kemudian dianalisis dengan GC dan GC-MS. Dad keselunten proses menurgukkan bahwa volume produk cair pirolisis dan pimfiss halal* campuran pohetilena-lempumng kelapa makin meningkat dengan meningkalnya jumlab palietilena di dalam campuran, Dale GC dan GC-MS menunjukkan bahwa proses pirolisis menghasilkan produk warna berupa senyawa hidrokarbon rantai karbon C4 - C11 dan proses pirolisis katakek menghasilkan senyawa hidrokarnon rantai karbon CS - C1.2 Polyethylene is a cdymer with dental structure as (-CflaCtitis, with n os repeal Mt, mama% coconut shell st Mains of cartutose 38,3%, lignin 28,3% and hernial:dose 25,1%. By Mang polyethylenessoconut shell in Manna conversion process without omen (pyrolisis), bopeally that polyethylene could act as hydrogen supplier sn the Mad hydrocarbon product can be increase. To know the effectiveness ot polyethylene contain to the hydrocarbon product, the variation of polyethylene- nut shell conwaston in paellas and catalytic pyrolisis masses have bee done. Natural zeolle from Wonosai was used as a catalyst. Natural zeolite catayst was made by: a-Ovation, calcination and hydrothermal processes. Duty gram of polyethylene-coodiut shell mixture by 5:1, 4:2, 3:3, 2:4, 1:5 ratio were pyrolized at 300°C. Organic as that mduced was condensed to get liquid product. For catalytic pwasis, catalyst was placed in the reactor. The liquid products ware analyzed by GC and GC-MS. From all processes showed that as the increase of polyethylene contain, liquid prcouct volume to pyrolisis and catalytic pintas of aolyethylene-coconut shell mixture was increase. The GC and GC-MS data showed that rte main product of pyrolisis are hydrocarbon compounds in 04-C11 range and the main product of catalytic pyrolisis are hydrocarbon compounds a 08-012 range.
