Upgrading Karakteristik Biopelet Tandan Kosong Sawit Dengan Penambahan Oil Sludge Sebagai Co-Firing

---

In making biopelet from empty palm oil bunch waste with the addition of oil sludge as co-firing, it is carried out using torefaction and disinfection methods. The torefaction method is a thermal conversion by decomposing the chemical bonds of lignocellulosic material consisting of hemicellulose, cellulose, and lignin contained in empty palm fruit bunches. The purpose of this study was to determine the effect of torefaction detention time on the analysis of proximate characteristics and biopelet calorific values, determine the effect of pressing pressure on the analysis of biopelet mechanical properties, determine the effect of adding oil sludge as co-firing on the analysis of biopelet characteristics and compare biopelet characteristics with quality standards biopelet ISO 17225-6. This research was conducted with two variable variations, namely: Fixed variables and changing variables. The fixed variables consist of raw material size, raw material ratio, torefaction temperature, biopelet size, particle size and flow rate of N2 used. And the variable changes consisted of torefaction detention time (30, 45 and 60 minutes) and pressing pressure (30, 40 and 50 bar). After drying naturally, the biopelet raw material is then torefactioned with a torefaction temperature of 275 ° C with changing variables and the results are analyzed for biopelet praxomato.. The production of biopelets is carried out with different variations in pressing pressure, in order to obtain a mechanical analysis and test the calorific value of the biopelet. The results of the praxeomic analysis showed that the detention time of torefaction was directly proportional to the increase in proximate characteristics and calorific value of biopelets with the best results of 3.35% moisture content, 8.66% ash content, 9.50% volatile content, 78.49% fixed carbon content, and the calorific value 4597.76 cal/g under the conditions of 60 minutes of torefaction detention time. The results of the biopelet mechanical analysis showed that the effect of pressing pressure was directly proportional to the increase in the mechanical properties of the biopelet with the best results of density 1.148 gr/cm3, compressive strength 16.86 bar, and porosity of the biopelet 13.33% under 50 bar pressure. The effect of the addition of oil sludge as co-firing resulted in the calorific value of the biopelet being lower than the calorific value of the empty palm fruit bunches. This is because the calorific value of oil sludge is lower than the heating value of empty oil bunches. In general, the biopelets produced have met ISO 17225-6 standards, except for the characteristics of the ash content. The obtained biopelet ash content ranged from 4.17 to 10.68% and the maximum allowed standard was 5%.
Keywords: empty palm fruit bunches, oil sludge, torefaction and densification methods, praxeomic analysis, mechanical analysis, porosity.
