Abstract
Otpadno jestivo ulje iz domaćinstva podvrgnuto je procesu transesterifikacije metanolom, uz KOH kao katalizator, u svrhu dobivanja biodizela. Cilj rada je provjeriti mogućnost uklanjanja vode iz biodizela, zaostale nakon ispiranja, pomoću zeolita klinoptilolita. Upotrijebljen je klinoptilolit različite veličine čestica (10 i 50 mikrona) i mase u rasponu od 0,5 do 2 grama. Određene su fizikalno – kemijske karakteristike otpadnog jestivog ulja: udio vlage, kinematička viskoznost, gustoća, kiselinski i peroksidni broj i fizikalno- kemijske karaktristike biodizela: gustoća, kinematička viskoznost te plamište. Rezultati pokazuju da se količina ostatne vode u biodizelu smanjuje povećanjem mase klinoptilolita korištenog za sušenje, ali nedovoljno da bi se zadovoljila norma o kvaliteti biodizela (ASTM D6751). Povećanjem mase klinoptilolita do četiri puta, ne uočava se proporcionalno snižavanje udjela vlage, ali pri većim udjelima klinoptilolit čestica većih dimenzija ima bolju sposobnost apsorpcije vode.
Abstract (english)
Waste edible household oil was subjected to a methanol transesterification process, with KOH as a catalyst, for the purpose of obtaining biodiesel. The aim of this work is to check the possibility of removing water from biodiesel, left after rinsing, using clinoptilolite zeolite. Clinoptilolite of different particle sizes (10 and 50 microns) and weights ranging from 0.5 to 2 grams were used. Physico-chemical characteristics of waste edible oil were determined: moisture content, kinematic viscosity, density, acid and peroxide number and physico-chemical characteristics of biodiesel: density, kinematic viscosity and flash point. The results show that the amount of residual water in biodiesel decreases with increasing mass of clinoptilolite used for drying, but not enough to meet the biodiesel quality norm (ASTM D6751). By increasing the mass of clinoptilolite up to four times, no proportional decrease in the moisture content is observed, but at higher proportions clinoptilolite particles of larger dimensions have a better ability to absorb water.
