Abstract

Biogas is an environmentally friendly renewable energy source. Biogas can be used using Palm Oil Mill Effluents (POME). However, the % yield of biogas productivity is still not optimum due to the low conversion. The biogas productivity can be optimized by adding methanogen bacteria which increase the methane production through the anaerobic fermentation process. This study aims to utilize cow manures as the source of methanogen bacteria in methane production from POME. Furthermore, this study specifically aims to obtain the optimum productivity condition of biogas production by the composition ratio of POME and cow manures to the amount of fermentation time at 35oC and 50oC for mesophilic and thermophilic bacteria, respectively. The ratio of POME and cow mature were A1 (100:0), A2 (80:20), A3 (70:30), A4 (60:40), and A5 (0:100). The highest yield of biogas production was A2 ratio using the thermophilic condition which showed 51.33% mol with the total solid decline of 73.43%, COD removal of 77.01%, and BOD removal of 70.02%.

Abstract

Inhibiting effect of nitrogen compounds in petroleum diesel (gas oil) on theperformance of the catalyst NiMo/Al2O3 and CoMo/Al2O3 uponhydrodesulfurization (HDS) has been investigated using an autoclave reactor.Operating conditions used was 340oC temperature and initial pressure 50 kg/cm2H2. Oil sample used was diesel oil and diesel oil-free nitrogen. Stages of thereaction between hydrogen replacement is intended to find out more about otherinhibiting effects derived from byproducts such as H2S and NH3. The entirecompound in diesel oil was analyzed by GC-AED before and afterhydrotreatment. Catalysts NiMo/Al2O3 and CoMo/Al2O3 showed different activityin HDS and the effect of nitrogen compounds. In principle, the HDS to type withhighly reactive sulfur / reactive will be more resistant to inhibiting properties ofnitrogen than sulfur compounds are hard to react (refractory). In contrast, forcatalysts showed como real effect of nitrogen compounds. One of refractorycompounds are 4,6-dibenzothiophene (4,6-DMDBT), can effectivelyhydrogenated by the removal of hydrogen compounds and renewal nitrogen onthe HDS. This result shows the synergistic effect due to dischargesimultaneously both types of block. Furthermore, in brief reactive nitrogencompounds in the HDS also discussed in this paper.Kata kunci: hydrodesulfurisasi, hambatan senyawa nitrogen, katalisNiMo/Al2O3, CoMo/Al2O3, GC-AED
