“…Palm shell also has low ash content, high density, and high carbon content which are desirable properties of a suitable precursor for the preparation of high activated carbon [6]. Aside from raw materials, characteristics such as surface area and pore structure of activated carbon largely depend on the activation method [7]. In this study, chemical activation by H3PO4 is used due to its ability to restrict lignin content and thus produce higher surface area [8].…”

The objective of the study is to obtain suitable adsorbent to be applied for the purification of hydrogen from hydrogen-methane gas mixture. The application will be used to increase the efficiency of process in refinery unit focusing on hydrogen supply as the feed of hydrocracking unit. One of the promising technology is adsorption. In this study, adsorbent used is utilized by palm shell based bioadsorbent activated carbon which is a potential raw material among others due to its carbon and lignin content also its abundant supply. The activated carbon is going through chemical activation using H3PO4 to increase its surface area. Characteristic test of produced activated carbon is measured to obtain surface area which resulted in BET surface area of 414.91 m2/g and iodine number of 716 mg/g. In this case, a detailed experimental study has been made for the adsorption of pure methane, and pure hydrogen at 20°C and CH4/H2 gas mixture at 10, 20, and 30°C isothermal condition with pressure variation for each isothermal condition 1 – 6 bar. Measurement were made using volumetric technique coupled with gas chromatographic analysis. The result of adsorption test shows at 20°C adsorption of pure CH4 was highest followed by mixture gas of CH4/H2 with 1.5% methane then pure H2. The adsorption of gas mixture for any composition of gas were increased with increasing pressure at all temperatures. At the same pressure, adsorption of gas mixture that composed of 8.5% methane at 10 and 30°C increased in lower isothermal condition. Based on gas chromatograph analysis, in all conditions methane in gas mixture is all adsorbed to activated carbon. The trend of isothermal adsorption also fits the Langmuir model of isothermal adsorption.

The main effort of this study was to enhance the enzymatic hydrolysis yields of cotton and viscose waste fibers via fed batch enzymatic hydrolysis. To do so, enzymes fed into slurries at two steps in fed batch mode. Also, the batch mode with the same amount of enzymes was implemented in order to be compared with the fed batch mode. The results showed that the released sugar contents from fed batch hydrolysis of cotton and viscose waste fibers were 29.0 and 32.3 g/l, respectively, but batch process released 25.0 and 30.3 g/l from cotton and viscose waste fibers, respectively, which confirms the increasing effect of fed batch process on the hydrolysis of both waste fibers. In addition, the morphological studies and enzymatic hydrolysis yields from pretreated cotton and untreated viscose waste fibers showed that alkali pretreatment for viscose waste fibers is not necessary, but has significant effect on enzymatic hydrolysis of cotton waste fibers; also, the differences in microcrystalline structures of viscose and cotton waste fibers have resulted in more enzymatic hydrolysis and then fermentation yields of viscose waste fibers. The amount of ethanol produced from cotton and viscose waste fibers were 6.9 and 8.1g/l, respectively.
