Kapok seed oil is an environmentally friendly biodiesel *** problem of the best catalyst for transester-ification of Kapok seed oil still continues *** research developed a base-heterogeneous catalyst with the effect of ultrasonic waves during ***,the study aims:(1)to determine the type of natural zeolite used,(2)to determine the characteristics of the synthesized CaO:BaO/ANZ catalyst,and(3)to determine the effectiveness of the CaO:BaO/ANZ catalyst in the biodiesel production process through sono-transeste rification of kapok seed *** research stages consisted of:(1)activation of natural zeolite and its characterization,(2)preparation of CaO:BaO/ANZ catalyst,(3)characterization of CaO:BaO/ANZ catalyst,(4)esterification and uti-lization of catalyst in the transesterification,(5)analysis of transesterified *** results showed that the natural zeolite type from the southerm area of Malang is mordenite(MOR)***,after the natural zeolite was impregnated,the obtained catalyst compositions were CaO:BaO-9:9/ANZ,CaO:BaO-14:9/ANZ,and CaO:BaO-4:11/ANZ with a surface area of 129.7;124.6;128.5 m^(2)/g,and acidity of 1.037;0.254;and 0.685 mmol/g,*** best catalyst for transesterification of kapok seed oil was CaO:BaO-9:9/ANZ,which resulted in a biodiesel yield of 73.6%with a density of 889.6 kg/m^(3) and kinematic viscosity of 2.987 *** characteristics of the produced biodiesel meet requirement of SNI 7182:2015.

Journal of Renewable Materials 2022年第11期10卷 2781-2789页

作者： aman santoso Amirotus Sholikhah Sumari Sumari Muhammad Roy Asrori Anugrah Ricky Wijaya Rini Retnosari Ihsan Budi Rachman Department of Chemistry Faculty of Mathematics and Natural SciencesUniversitas Negeri MalangMalang65145Indonesia Department of Chemistry Faculty of Science and TechnologyUniversiti Kebangsaan Malaysia UKM BangiSelangor43600Malaysia Graduate School of Engineering and Science Shibaura Institute of TechnologySaitama3378570Japan

Plastic is a basic need for humans,but it has also caused big problems for the ***,the purpose of this study was to determine the effect of the type of plastic and the addition of a zeolite catalyst on the oil yield from the pyrolysis of plastic *** research stages were natural zeolite activation,pyrolysis reactor settings,pyrolysis of plastic waste(PP and LDPE types),and *** results showed that the used natural zeolite had a mordenite phase and activated natural zeolite had a higher Si/Al ratio than the inactivated *** addition of a zeolite catalyst had an effect on the produced *** yields of oil from plastic waste pyrolysis with zeolite catalyst for PP and LDPE plastics were about 75.9 and 76.9 w/w,*** results of the GCMS analysis showed that the compounds of the pyrolysis oil were thought to be from the alkanes,cycloalkanes,alkenes,carboxylic acids with aromatic rings,and *** results of the GC-MS test showed that the uncatalyzed pyrolysis product consists of compounds with a range of C5-C11 carbon ***,the ranges of pyrolysis products with active zeolite catalyst were C6-C24 carbon chains.
