Studi Karakteristik Komposisi Produk Katalitik Pirolisis TKKS dengan katalis Al White

Abstract

Bio-oil can be produced from biomass which has the potential to become an environmentally friendly renewable energy source. Most of the biomass is found as organic waste or used as mulch. Therefore, this renewable energy source needs to be developed so that its utilization can be maximized as a promising energy source with a catalytic pyrolysis process. The raw material used in this research is empty palm fruit bunches (EFB). The purpose of this study was to determine the effect of catalytic pyrolysis temperature on pyrolysis products in the form of char, bio-oil and gas. The experiment was carried out at various temperatures of 300°C, 350°C and 400°C using Al white catalyst. The ratio of Al white catalyst with EFB is 1:2 mixed with the catalyst in the pyrolysis reactor. The desired temperature for the pyrolysis process can be set on the reactor temperature controller. The results showed that the optimum bio-oil production rate of 55.81% was obtained from samples at 350 °C. Bio-oil in this study was divided into BO (bio-oil in the oil phase) and BA (bio-oil in the liquid phase). In this study the bio-oil obtained at process temperatures of 300°C, 350°C and 400°C were 45.28%, 55.81% and 47.40%, with a heating rate of 5.93°C/minute , 6.11 °C/minute, and 6.68 °C/minute and the density of bio-oil ranges from 1.114–1.264 g/ml. BO products are thicker than BA products. BO viscosity is higher at high pyrolysis temperature as well. The most char products at 300oC and the most gas products at 400oC. The higher the pyrolysis temperature, the more gas will be produced. By improving the pyrolysis process, promising bio-oil can be produced with temperature, catalyst treatment, and heating rate playing an important role in it
