Abstract

Sodium benzoate is a preservative compounds which are widely used for both food and beverage products. The treatment of waste water containing this compound was normally conducted in a anaerobic digestion (AD) using a batch reactor system at a room temperature. The anaerobic process eventually produced biogas which can be used for bioenergy. This research was aimed to evaluate the production of biogas from by synthetic solution models containing sodium benzoate (SB). The experiment was performed in a variation of Mixed Liquor Suspended Solid (MLSS) of 4.8 and 7.2 g/L, and initial sodium benzoate concentration of 400, 600, and 800 mg/L. The digestion was performed at 60 days, while the biogas content was measured every 2 days. The results indicated a reduction in the cumulative biogas by the addition of sodium benzoate, compared to the control condition. Moreover, the decrease in organic loading rate (OLR) of SB in wastewater follows the first order kinetic with kinetic rate constant (k) was 0.0432 to 0.1254 (day−1) for MLSS of 4.8 g/L and 0.0276 to 0.0372 (day−1) for 7.2 g/L MLSS. Copyright © 2021 by Authors, Published by BCREC Group.

Abstract

Nyamplung (Calophyllum inophyllum) is a typical Indonesian plant. Its seed contains abundant inedible oil, and therefore it is potential for biodiesel feedstock. The current issues of biodiesel are longer  reaction time of oil to biodiesel through transesterification reaction and lower biodiesel yield due to ineffective use of a homogenous catalyst. This work was aimed to use an ionic liquid as a catalyst and equipped with microwave heating as the heating system in order to increase the biodiesel yield and accelerate the process. Effects of the catalyst concentration and power of microwave irradiation to the biodiesel yield were studied. The ionic liquid of 1-butyl-3-methylimidazolium hydrogen sulfate (BMIMHSO4) was used as a catalyst. The results showed that the highest biodiesel yield was achieved of 92.81% which was catalyzed by IL0.5NaOH0.5 (0.5 wt.% (BMIMHSO4) + 0.5 wt.% NaOH) with a methanol-to-oil molar ratio of 9, a reaction time of 6 minutes, and the microwave temperature was 60 °C.

Abstract

The sugar palm tree (Arenga pinnata) was abundant in Indonesia and has high cellulose contents for bioethanol production. However, the lignin content was the major drawback which could inhibit saccharification enzymes and therefore removing the lignin from the biomass is important. This paper evaluated the effects of pretreatments  using nitric acid (HNO3) and ammonium hydroxide (NH4OH) at 2 to 10% (v/v) on reducing sugar and ethanol contents and compared with the effects of steam pre-treatment. The pretreated samples were hydrolyzed using cellulase enzymes at pH 5.0 with a substrate concentration of 10% (w/v) for 24 to 72 h at 50 °C. Subsequent assessments of enzymatic saccharification following pre-treatment with 10% (v/v) HNO3 showed maximum reducing   and total sugar contents in palm tree trunk waste of 5.320% and 5.834%, respectively, after 72 h of saccharification. Following pretreatment with 10% (v/v) of NH4OH, the maximum reducing and total sugar contents of palm tree trunk waste were 2.892% and 3.556%, respectively, after 72 h of saccharification. In comparison, steam pretreatments gave maximum reducing sugar and total sugar contents of 1.140% and 1.315% under the same conditions. Simultaneous saccharification and fermentation (SSF) was conducted at 37 °C (pH 4.8) and 100 rpm for 120 h using 10% (v/v) Saccharomyces cerevisiae and cellulase enzyme with a substrate concentration of 10% (w/v). The result showed the highest ethanol content of 2.648% was achieved by using 10% (v/v) HNO3. The use of 10% (v/v) NH4OH gained a yield of 0.869% ethanol while the steam pretreatment could obtained 0.102% ethanol.

Abstract

Nowadays, the use of homogenous catalyst has been gradually reduced for its operational reason. The homogenous catalyst leads in difficulty of separation after the process completed and the life cycle is shorter. Therefore, most of researches are introducing heterogenous catalyst for its substitution. This research was aimed to evaluate the use of shell of Anadara granosa and CaCO3 as source of CaO based catalyst through impregnation method. The preparation of the catalyst was started by decomposition of shells and CaCO3 at temperature of 800 oC for 3 hours, followed by impregnation at 70 oC for 4 hours and then calcined at 800 oC for 2 hours. The CaCO3 based catalyst gained high yield of biodiesel (94%) as compared to Anadara granoasa based catalyst (92%). The reusability study showed that these catalysts could be used until three times recycle with 40-60% yield of biodiesel. The CaO contents of catalyst decreased up to 90% after three times recycles.

Abstract

The application of heterogeneous solid acid catalysts in biodiesel production has become popular and gained significant attention over the last few years. It is since these types of catalysts hold the benefits in terms of easy separation from the product, reusability of the catalyst, high selectivity of the reaction. They are also considered sustainable and powerful particularly in organic synthesis. This work studied the use of tin(II) chloride as solid Lewis acid catalyst to promote the esterification reaction of high Free Fatty Acid (FFA) jatropha oil in continuous reactive distillation column. To obtain the optimum condition, the influences of reaction time, molar ratio of the reactant, and catalyst were investigated. It was revealed that the optimum condition was achieved at the molar ratio of methanol to FFA at 1:60, catalyst concentration of 5%, and reaction temperature of 60°C with the reaction conversion of 90%. This result was significantly superior to the identical reaction performed using batch reactor. The esterification of high FFA jatropha oil using reactive distillation in the presence of tin(II) chloride provided higher conversion than that of Amberlyst-15 heterogeneous catalyst and was comparable to that of homogenous sulfuric acid catalyst, which showed 30 and 94.71% conversion, respectively. The esterification reaction of high FFA jatropha oil was subsequently followed by transesterification reaction for the completion of the biodiesel production. Transesterification was carried out at 60 °C, molar ratio of methanol to oil of 1:6, NaOH catalyst of 1%, and reaction time of one hour. The jatropha biodiesel product resulted from this two steps process could satisfy the ASTM and Indonesian biodiesel standard in terms of ester content (97.79 %), density, and viscosity.

Abstract

Whey is the liquid remaining after milk has been curdled and strained. It is a by-product of the manufacture of cheese or casein and has several commercial uses. In environmental point of view, whey is kind of waste which has high pollution level due to it’s contain high organic compound with BOD and COD value 50 and 80 g/L respectively. On the other side, whey also contain an amount of lactose (4.5%-5%); lactose can be used as carbon source and raw material for producing ethanol via fermentation using yeast strain Kluyveromyces marxianus. The objective of this research is to investigate the ethanol production kinetics from crude whey through fermentation using Kluyveromyces marxianus and to predict the model kinetics parameter. The yeast was able to metabolize most of the lactose within 16 h to give 8.64 g/L ethanol, 4.43 g/L biomass, and remain the 3.122 g/L residual lactose. From the results presented it also can be concluded that common kinetic model for microbial growth, substrate consumption, and product formation is a good alternative to describe an experimental batch fermentation of Kluyveromyces marxianus grown on a medium composed of whey. The model was found to be capable of reflecting all batch culture phases to a certain degree of accuracy, giving the parameter value: μmax, Ks, YX/S, α, β : 0.32, 10.52, 0.095, 1.52, and 0.11 respectively.© 2013 by Authors, Published by BCREC Group.
