“…Rather than capturing CO2 and CH4, the consumption of two natural abundant GHGs is undoubtedly an attractive route to reduce the GHG in an environmental-friendly way. In this regard, dry reforming of methane (DRM) was introduced by reacting both GHGs, forming a mixture of hydrogen (H2) and carbon monoxide (CO) generally known as syngas (Winanti et al, 2014). This is a feasible way to reduce GHGs without complicated and expensive separation process ( San-José-Alonso et al, 2009;Rubin et al, 2015).…”

In the past decade, efforts have been focused on development of catalyst to show high activity for dry reforming of methane (DRM). The development of catalyst has been crucial to be carried out as this may significantly reduce the concentration of most common greenhouse gases, namely methane (CH4) and carbon dioxide (CO2) in the atmosphere. In present work, a series of varying molar ratio of Ni:Ce metal organic framework (MOF) derived catalysts were grown on alumina in one step. The synthesis steps were in accordance to reported solvothermal method for the syntheses of NH2-MIL-88B with slight modification. This was followed by reduction at 500C in hydrogen environment for 1 h. The physical and chemical properties of the catalysts were probed by powder XRD, BET surface area analysis, EDX, ICP, CO2-TPD and H2-TPR. XRD showed that diffraction patterns were in agreement with the diffraction pattern of MOF synthesized in previous work, thus confirmed the successful formation of the MOF structure. The variation in the molar ratio of Ni:Ce did not show significant difference in the diffraction pattern of the MOF-derived catalysts. For reduction phase, sharp diffraction peaks were detected at 2θ = 44.5, 51.85, and 76.37, which can be indexed to (1 1 1), (2 0 0) and (2 2 0) planes of face-centered cubic (FCC) metallic Ni, respectively. The addition of Ce promoted smaller particle size of Ni, ranging from 4.6 nm to 6.88 nm. The presence of CeO2 was observed at 2θ = 28.6, 33.0, and 56.4. Elemental distribution was compared between EDX and ICP-OES. ICP-OES and EDX analyses indicated that weight percent of bimetallic metal of Ni and Ce was consistent, in which the amount of respective metal obeyed the ratio trend of the metal precursors added during the MOF synthesis. This suggested the homogeneity of the catalyst, even though EDX showed relatively higher weight percent than ICP-OES. The catalytic performance of catalysts showed that 1Ni1Ce exhibited better conversion of CH4 and CO2, with 63.5% and 86.8% respectively at 800 o C, and the conversion tend to increase at a higher temperature. The results were convincing for the design of a performing catalyst for DRM process.

“…As one of the greenhouse gas emissions, CO2 can be decomposed into CO and O2 in a three-pass-flow DBD reactor, a reactor designed so that the gas stream of the reaction has a special configuration. This configuration can simultaneously cool the high voltage electrode (HVE) during the reaction process and preheat the gas feed stream before entering the plasma zone (Winanti et al, 2013).…”

A dielectric barrier discharge (DBD) plasma reactor for carbon dioxide (CO2) decomposition was developed to address the current phenomena of CO2 emissions exceeding 400 ppm in the atmosphere. As is widely known, CO2 is one of the main causes of global warming and climate change. In this research, a parallel plate plasma reactor was designed by modifying the DBD reactor configured with two parallel electrodes. The casing of the reactor was modified using an acrylic plate that acts as a shell for the optimal contact between the CO2 gas and the electrodes. The DBD reactor uses a 220 VAC line power (PLN), 5060 Hz frequency. The performance of the DBD reactor was tested and optimized by varying the regulator output (AC) voltage and the CO2 feed flow rate to obtain the optimal operating conditions from the parallel plate plasma reactor for decomposition of CO2. The optimal process performance for the 7-gram (ozone production equivalent) plasma reactor was achieved at a discharge power of 82 Watts and a feed flow rate of 1.2 L.min-1 with CO2 conversion of 4.413% and energy efficiency of 2.093×10-3 mol.J-1. The optimal process performance for the 10-gram (ozone production equivalent) plasma reactor was achieved at a discharge power of 74 Watta and a feed flow rate of 1.2 L.min-1 with CO2 conversion of 3.949% and energy efficiency of 2.074×10-3 mol.J-1 .

Increased production in the textile industry has the potential to result in high dye waste water. Various conventional methods to handle with textile waste treatment have been done, but still considered not yet or less effective. The AOP technology (Advanced Oxidation Processes) applied in this research is a rapid degradation technology in textile wastes with advanced oxidation process through the formation of hydroxyl radical (OH) which is considered to optimize the degradation process of textile dye waste. This study aims to evaluate the performance of ozonation methods and AOP (O3/UV/H2O2) in dye degradation of textile wastewater containing remazol blue compounds. Both configuration methods used are optimized in several parameters such as waste flow rate, ozone voltage and pH to obtain maximum remazol blue degradation. From this study, the higher percentage to remazol blue degradation is 99.99%, which is achieved by AOP method, with double air injection air flow rate of 10 L/min and 0.25 L/min liquid flow rate.
