“…For example, the ZSM-5 catalyst has a surface area of 306,178 m2/g, compared to 3,788 m 2 /g for the Cu/ZSM-5 catalyst, which has a surface area of 302,390 m 2 /g. According to Dewajani et al (2016), The more metal that is evenly distributed on the surface of the catalyst is expected to increase the specific surface area, but conversely, the increasing percentage of activating metal causes the surface area to decrease. This is due to the accumulation of metals at the pore mouths or pore channels or the activating metal being dispersed unevenly on the surface, causing less nitrogen gas to be adsorbed so that the specific surface area of the catalyst decreases with the increasing amount of metal.…”

The number of watercrafts in the sea will have an impact on the amount of waste lubricant oil that is discharged into the sea, which ultimately results in pollution. The increasing level of hazardous and toxic materials (B3 waste) is concerned to have a wider impact on public health and environment quality. One of the B3 wastes that requires special handling due to its high quantities is used lubricating oil. Utilization and processing of waste lubricant oil discharged from the ship is an alternative that can be applied to reach efficient consumption of petroleum which is shrinking from year to year. Therefore, we need a processing method that can reduce the pollutants generated from the waste, one of which is the Acid Clay Treatment method. This treatment aims to determine the best conditions for reducing heave metal lead (Pb) through Acid Clay Treatment method and to assess the decrease in Pb concentration contained in used lubricating oil from ship. The adsorbent used was clay that has been activated with sulphuric acid. The processing of used lubricating oil was carried out using three variations, including adsorbent concentration, contact time, and acidity (pH). The test results of used oil lubricating oil processing were 15 gram of adsorbent concentration, 90 minutes of contact time, and pH 4. The Pb reduction efficiency obtained from Acid Clay Treatment method in the best conditions was 53.72%.

“…The reason why that the presence of B 2 O 3 in the mixture of the catalyst have no significant effect on the product distribution of the mono-aromatic compounds is due to the mixing process of HZSM-5 catalyst and B 2 O 3 wasn't done using the proper method. There are several methods for catalyst mixing, which one of the best way is by impregnation [5]. Impregnation is a process where the porous support is impregnated with a solution of a compound of the desired catalytic constituent.…”

The catalytic conversion of rice straw was done to produce mono aromatic compounds. The mixed catalyst of ZSM-5 and B2O3 was obtained through calcination of ZSM-5 and H3BO catalyst mixture. The variation of the composition of the ZSM-5 and B2O3 catalyst was applied in order to test the effect of catalyst composition to the production of mono aromatics compounds. The composition of catalyst used were 15% ZSM-5, 30% ZSM-5, and 100% ZSM-5. Other than the variation of catalyst composition, the variation of the operating temperature of the catalytic conversion also performed in order to study the effect of the temperature to the production of mono aromatic compounds. The catalytic conversion was done at 450, 475, and 500 oC. Experimental results show that the addition of the catalyst resulted in the conversion of oxygenate compounds resulted from the pyrolytic process of rice straw into mono aromatic compounds. It also shows that using 100% ZSM-5 produced the highest yield of mono aromatics compounds. The amount of mono aromatic compounds produced will decrease, as the fraction of ZSM-5 catalyst used and operation temperature also decreased. Using the 100% ZSM-5, the mono aromatics compound with the highest yield is 1, 3 Dimethyl benzene or mxylene.

“…The larger the pore the more its ability to adsorb molecules with a bigger size. Conversely, if the pore diameter is small, it will only be able to adsorb small molecules (Dewajani, 2016). The increase in pore radius of the catalyst occurs due to the opening of active SiO2 pores during the impregnation process with MgO-CaO and the calcination process.…”

Energy demand will increase along with the increase in population. The current energy demand is dominated by non-renewable energy as it could reduce dependence on fossil energy sources; hence, it is imperative to be developed. Biodiesel with waste cooking oil as its raw material is one of the renewable energies currently being developed. Catalyst can be utilized to improve the quality of biodiesel product and process. The major content in solid waste of geothermal power plant is silica oxide, while dolomite contains magnesium oxide and calcium oxide. This study aims to test the MgO-CaO/SiO2 catalyst performance from geothermal waste and dolomite in biodiesel production. The results of catalyst characterization based on FTIR, SEM, and BET tests indicates a successful impregnation method in MgO-CaO/SiO2 catalyst production. The result shows that the best variable to produce biodiesel is at the ratio of MgO-CaO: SiO2 is 15:85. The conversion of biodiesel using this variable is 92.63%. The overall results of biodiesel obtained in this study have a good quality and is in accordance with SNI 7182-2015.
