Abstract

Composites based on layered double hydroxide with polyoxometalate K3[-PW12O40] and K4[-SiW12O40] were synthesized to form NiAl-[SiW12O40] and NiAl-[PW12O40]. The materials were characterized by XRD, FTIR, SEM, and UV-DRS and were then applied as a photocatalyst to degrade MG. The effects of catalyst loading, pH value, and contact times on photodegradation performance were carried out in this study. The results indicated that        NiAl-LDH was successfully synthesized by showing the peak diffractions at angles 11.63°, 23.13°, and 35.16°. Both kinds of attained NiAl-[SiW12O40] and NiAl-[PW12O40] had typical structures of LDH that were proved by appearing diffraction at 2θ angles 10.76°, 26.59°, 30.8°, and 63.11° for NiAl-[PW12O40] and at 2θ angles 8.26°, 11.34°, 29°, and 35.1° for NiAl-[SiW12O40]. The materials used for the fifth regeneration were characterized by FTIR, which still presents characteristics of LDH structure. The photocatalyst was applied for the first time to degrade MG. The decrease of band gap on NiAl pristine than LDH composite from 4.76 eV to 3.22 eV for NiAl-[SiW12O40] and 3.78 eV for NiAl-[PW12O40] respectively, was presented by DR-UV analysis. LDH composite shows improved degradation photocatalytic performance in comparison with LDH pristine. It was present by the %degradation MG performances were 68.94% for NiAl LDH, 84.51% for NiAl-[PW12O40]), and 88.91% for NiAl-[SiW12O40]. The degradation percentage indicates that the LDH-polyoxometalate composite has succeeded in increasing the ability of photodegradation catalytic and the regeneration ability of LDH pristine.

Abstract

Composite M2+/Al-BC (Ca/Al-BC, Cu/Al-BC, and Ni/Al-BC) have been successfully synthesized. Composite and pristine materials were used as adsorbents of cadmium(II) [Cd(II)] in an aqueous solution. Firstly the performance of composite and pristine materials was evaluated by reusability properties until five cycles adsorption process followed with a determination of isotherms and adsorption thermodynamic properties. The results show composite has ten-fold surface area properties than starting materials. The adsorption capacities of CaAl-BC, CuAl-BC, and NiAl-BC at a temperature of 333 K were 156.250 mg/g, 149.254 mg/g, and 208.333 mg/g, respectively.

Abstract

Among the several ways used in wastewater treatment, the photocatalysis process is a more novel and alternative process that is increasingly employed in recent years. This work aims to improve the performance of the photocatalyst process by using air bubbles in removing the BTEX from produced water as an indicator of process efficiency. The study also shows the effect of influencing factors (pH and residence time) on the photocatalysis process. The study was done in a rectangular column with dimensions of 200 mm width, 30 mm depth, and 1500 mm height. Commercial titanium oxide (TiO2) coated on a plate by the varnish was used as a source of the photocatalyst. The experiment was carried out under different values of gas flow rate (0-3 L/min) to evaluate its effect on the photocatalyst process, the effect of other variables of pH (3-11), and irradiation time (30-120) min was also studied. A new method of the coating was adopted by using an alumina plate with varnish as an adhesive. The characteristics results show that the coated plate has hydrophilic properties and that there is no significant change in the crystal structure of the TiO2 nanoparticles and the varnish before and after 60 h of the photocatalytic process, indicating that the plate is still effective after 60 h usage under different conditions. The results also show that the introduction of air bubbles enhances the removal efficiency of BTEX significantly and the best removal effectiveness of BTEX was 93% when pH = 5 after 90 min and 90% when pH = 3 after 120 min. The removal rate also reached 86% when pH = 7 after 120 min all at a flow rate of 3 L/min. The percentage of removal decreased at pH = 9 and 11, reaching 64% and 50%, respectively after 120 min and a flow rate of 3 L/min. Copyright © 2022 by Authors, Published by BCREC Group.

Abstract

Nickel supported Parangtritis beach sand (PP) catalyst for hydrocracking of palm and malapari oil into biofuel has been conducted. The impregnation process of Nickel (Ni) metal on PP was carried out through the dry impregnation method (blending) using a precursor salt of NiCl2.6H2O with variations of Ni metal as much as 10 and 15 wt% of PP which produced Ni(A) and Ni(B) catalysts. Each catalyst was tested for activity and selectivity through the hydrocracking process of oil into biofuel using a semi-batch system reactor at a temperature of 450 oC, a hydrogen gas flow rate of 20 mL/minute for 2 hours, and a weight ratio of 1:200 catalyst:feed (w/w). The results showed that the Ni(A)/PP catalyst had the highest activity and selectivity with the yield of liquid products and the total biofuel fraction (biohydrocarbons) obtained from hydrocracking of palm oil of 68.50 and 49.87 wt%, respectively. Ni(A)/PP catalyst has a total acidity, surface area, and crystal size of 0.051 mmol/g, 4.44 m2/g, 25.86 nm, respectively. The reusability test of the Ni(A)/PP catalyst in the hydrocracking process of palm oil into biofuel after the third use resulted in a liquid product and the total biofuel fraction obtained was 64.20 and 41.46 wt%, respectively. The yield of liquid product and the total fraction of biofuel (biohydrocarbon) in hydrocracking malapari oil were 66.10, 47.83 wt%, respectively.

Abstract

A series of heterogeneous catalysts based on cobalt supported on SBA-15 were prepared through wet impregnation and co-impregnation assisted by ethylene glycol (EG) methods. The cobalt oxide catalysts generated after the drying and calcination process were denoted as CoO/SBA-15w and CoO/SBA-15c for a wet- and co-impregnation method, respectively. Subsequent to the reduction process, the reduced cobalt catalysts were obtained and denoted as Co/SBA-15w and Co/SBA-15c. The TEM images revealed the catalysts prepared through these methods show very clear distinctions that the catalyst prepared by wet impregnation shows large aggregates of cobalt particles on the external surface of SBA-15 due to their inability to enter the channels. The catalysts were evaluated on the hydrocracking of pyrolyzed -cellulose as a biomass model. The results showed that the reduced cobalt-based catalysts are having higher conversion value and selectivity towards the 2-furancarboxaldehyde reached ca. 20%.
