Abstract

Pyrolysis of meranti sawdust (Shorea spp) with Ni/SBA-15 catalyst at 350°C, 450°C and 550°C using the pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GC/MS) technique was carried out. This research was conducted to determine the pyrolysis product and the chemical composition of the pyrolysis product of meranti sawdust catalyzed by Ni/SBA-15 (20%wt.%). Based on the area percentage of products identified on the pyrogram, the chemical compositions of the pyrolysis product of meranti wood were 32.4%-43.6% products derived from cellulose/hemicellulose and 32.7%-23.3% products derived from lignin. The addition of Ni/SBA-15 catalyst to the pyrolysis of meranti sawdust increased the formation of cellulose/hemicellulose derivative products such as furan and furfural, as well as lignin derivative products such as vanillin. However, increasing the concentration of the catalyst also improved the amount of acetic acid, which is potentially corrosive and detrimental. Keywords: Pyrolysis, Meranti sawdust, Catalyst Ni/SBA-15, Py-GC/MS

Abstract

Pyrolysis study of Ulin (Eusideroxylon zwageri) sawdust in the presence of Ni/SBA-15 using a pyrolysis-gas chromatography-mass spectroscopy (Py-GC/MS) instrument has been carried out. This study aims to determine the chemical composition of pyrolysis products of Ulin sawdust after the addition of Ni/SBA-15 catalyst. Pyrolysis was carried out at 350, 450 and 550 ºC under helium (He) gas. Based on the percent area of the pyrolysis product identified on the pyrogram, the product of lignin derivatives before the addition of the Ni/SBA-15 catalyst was 58.53-68.14% and after the addition of the Ni/SBA-15 catalyst decreased to 51.08-58.33%. While the cellulose/hemicellulose derivative products before the addition of the Ni/SBA-15 catalyst were 15.62-17.78% and after the addition of the Ni/SBA-15 catalyst increased to 18.91-25.79%. Ulin sawdust catalyzed pyrolysis produced compounds with the highest area percent, namely catechol, isoelemicin, 2-Methoxy-4-vinylphenol, 1,6-anhydro-beta-D-Glucopyranose, and hydroxy-acetaldehyde. Keywords: pyrolysis, Eusideroxylon zwageri, Py-GC/MS, Ni/SBA-15 catalyst

Abstract

Pyrolysis experiments of bagasse with catalyst Ni/SBA-15 at 350°C, 450°C and 550°C using a Pyrolysis-Gas Chromatography-Mass Spectrometer (Py-GC/MS) been done. This study aims to determine the chemical composition of the pyrolysis product of bagasse with Ni/SBA catalysis (10% w/w). Based on the percent area value of the pyrolysis product identified on the pyrogram, the chemical composition of the pyrolysis product of bagasse produced was a cellulose/hemicellulose derivative product of 45.46%-60.24% and a lignin derivative product of 32.81%-17.77% . The addition of the catalyst Ni/SBA-15 to the pyrolysis of bagasse increased the amount of cellulose/hemicellulose derivative products such as ketones and furfural and then increased the amount of lignin derivative products such as vanillin and phenol. Keywords: Pyrolysis, Baggase, Catalyst Ni/SBA-15, Py-GC/MS
