The objective of this study was to improve the properties of rubberwood and jabon pellets through torrefacation. Torrefaction was performed at a temperature of 300°C and a residence time of 3 min, using Counter-Flow Multi Baffle (COMB) Dryer/Pyrolizer. The properties of torrefied wood pellets as equilibrium moisture content (EMC), density, and heating value. Black pellets were succefully obtained after torrefaction using COMB Dryer/Pyrolizer. The EMC of the black pellets from rubberwood and jabon was 3.54% and 2.85%, which is remarkably lower that their initial EMC of 12.25% and 12.76%, for rubberwood and jabon pellets, respectively. The density of black pellets from rubberwood and jabon and decreased 16.18% and 13.44% compared to control. Torrefaction using COMB Dryer/Pyrolizer also increased high heating value of wood pellets to 18.32% and 79.70%, for rubberwood and jabon pellets, respectively. Consequently, torrefaction using the COMB Dryer/Pyrolizer could improve the bioenergetic properties of jabon and rubberwood pellets.","PeriodicalId":374590,"journal":{"name":"Proceedings of the International Conference on Sustainable Biomass (ICSB 2019)","volume":"218 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121039632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, a physicochemical pretreatment method is needed by applying a non-thermal pulsed electric field (PEF) and alkali methods to increase the cellulose availabilities with a short process and low energy input. The aim of this study was to analyze the lignocellulose content of corncob biomass by using non-thermal pulsed electric fields (PEF) and NaOH pretreatment. The pretreatment factors used were the electric field strength of PEF and the pretreatment time. Analysis of the structure and elements of the lignocellulose based on the characteristics of the gravimetric method and SEM-EDX for untreated and treated samples. The results showed that pretreatment of corncobs biomass by using PEF optimally at an electric field strength of 9 kV/cm and pretreatment time of 60 seconds that was increasing cellulose of 40.59% when compared with the control and also decreasing the hemicellulose and lignin content of 12.9% and 2.02%, respectively. Under these conditions, the energy per pulse and specific input energy of PEF required 0.0205 J and 8.72 kJ/L, respectively. The microstructure analysis by using SEM-EDX showed significantly visual differences and was an increase in the percentage of C and O atoms between untreated and treated corncob biomass. Furthermore, the corncob biomass treated by using non-thermal PEF and alkali can become effective and efficient for the next process into cellulose-derived products.Keywords: corncob biomass; pulsed electric field; NaOH; pretreatment; cellulose","PeriodicalId":374590,"journal":{"name":"Proceedings of the International Conference on Sustainable Biomass (ICSB 2019)","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126879598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
