Abstract

The investigations of methyl oleate (methyl 9-octadecenoate) to convert 1-octadecanol, has been done. The conversion was carried out using ZSiA catalysts and fixed bed reactor that was operated at 400, 450, and 500 oC. ZSiA catalyst was prepared by washing zeolite with aquadest, followed by dipping in HCl 2M solution, adding Na2SiO3 5% b/b, dipping in NH4Cl 2M, calcination at 500 oC under nitrogen with flow rate of 20 mL/min for 2 hours, oxydation under oxygen flow rate of 20 mL/min. Characterization of the catalyst included determination of metal content using AAS, acidity using gravimetric method, surface area using Gas Sorption Analyzer NOVA 1000, and crystallinity using XRD. The fixed bed reactor was filled by catalyst and heated up to 400 oC under hydrogen flow rate of 20 mL/min. Then the feed (methyl oleate or methyl 9-octadecenoate) in evaporator was heated up to 400 oC under hydrogen flow rate of 20 mL/min. The reaction product was collected in glass tube and analyzed using GC-MS. Catalytic hydrogenation of methyl oleate produced 87,21% of 1-octadecanol as major product. 1-octadecanol product decreased significantly by the increase of hydrogen flow rate from 20 to 60 mL/min and for 5 to 15 grams catalysts.Keywords: methyl oleate, 1-octadecanol, ZSiA catalysts

Abstract

Abstract - Investigation of increasing waste cooking oil quality have been done using H-zeolite as an adsorbent and fluid fixed bed reactor which was operated in a various temperatures. H-zeolite adsorbent was prepared through physical and chemical treatments as follows : washing, acid, calcination and oxidation. The characterization of this adsorbent covered cations contain (Pb, Cu, Zn, Na, K, Ca and Fe) using AAS, Si/Al ratio using AAS, surface area spesific, pore volume and pore diameter using surface area analyzer NOVA 1000 and acidity using gravimetric method with amonia adsorption. Quality parametric of cooking oil that was investigated covered water contain, acid and peroxide value and density. Waste cooking oil as a sample was cooking oil which have been used for frying kerupuk, tempe and tahu three times. Fifty milliliter waste cooking oil was flowed throught 10 g H-zeolite adsorbent in fluid fixed bed reactor which was operated at various temperatures (50, 70, 90, 110 oC). The oil was placed in the bottle to be analyzed. The results of this research showed that the adsorpstion process for increasing quality of waste cooking oil using H-zeolite adsorbent  and fluid fixed bed reactor could reduce the water contain, acid and peroxide value and density. The optimum temperature was 70 oC. Keywords :zeolite, waste cooking oil, acid and peroxide value
