“…SNZ-Cal diffractogram reveals that the carriers contain clinoptilolite, mordenite, and quartz crystals with amorphous and crystalline phases. In addition, same result was reported by Gultom et al (2016) [23]. The main diffractogram peaks that confirm the presence of zeolite are at 2 = 20.10°, 22.05°, 28.46°, 29.70° (clinoptilolite phase), and 2 = 24.49°, 25.68°, 27.88°, 35.70° (modernite phase).…”

This research was aimed to investigate the effect of Co and Co-Mo metal loaded on Sarulla Natural Zeolite which has been activated and calcined (SNZ-Cal) as supports for better understanding of characterization and catalytic activity on hydrocracking of MEFA rubber seed oil. The Co and Co-Mo metal was added through a wet impregnation method using Co(NO3)2·6H2O and (NH4)·6Mo7O24·4H2O precursor salts. The catalyst was oxidized at 500 °C for 2 h within oxygen gas flow, followed by a reduction process with H2 gas flow with similar condition to obtain the catalysts. Based on the result, it was found that the resulted catalysts displayed an increase in crystal grain size compared to the metal-free catalyst. Particularly, catalyst that was impregnated with Co metal has a larger surface area and pore diameter and smaller pore volume than Co-Mo metal impregnated to the catalyst. In fact, it was revealed that this catalyst possessed the highest catalytic activity and selectivity. Furthermore, the resulting gas products reached 64 wt.% and the distribution of biogasoline fraction of hydrocarbons (C6-C12) amounted to 83.19 wt.%.

“…It can be observed that the Z/COPUF and AC/COPUF had a lower volume compared to B/COPUF. Previous studies have reported the foam shrinkage after the addition of fillers due to the increase of foam density, which similarly happened in this research [23,30,31]. It is then confirmed by the relatively more closed pore structure in Z/COPUF and AC/COPUF from the images shown in Figure 4.…”

Filler-Modified Castor Oil-Based Polyurethane Foam for the Removal of Aqueous Heavy Metals Detected Using Laser-Induced Breakdown Spectroscopy (LIBS) Technique

et al. 2020

The use of polymeric material in heavy metal removal from wastewater is trending. Heavy metal removal from wastewater of the industrial process is of utmost importance in green/sustainable manufacturing. Production of absorbent materials from a natural source for industrial wastewater has been on the increase. In this research, polyurethane foam (PUF), an adsorbent used by industries to adsorb heavy metal from wastewater, was prepared from a renewable source. Castor oil-based polyurethane foam (COPUF) was produced and modified for improved adsorption performance using fillers, analyzed with laser-induced breakdown spectroscopy (LIBS). The fillers (zeolite, bentonite, and activated carbon) were added to the COPUF matrix allowing the modification on its surface morphology and charge. The materials were characterized using Fourier-transform infrared (FTIR), scanning electron microscopy (SEM), and thermal gravimetry analysis (TGA), while their adsorption performance was studied by comparing the LIBS spectra. The bentonite-modified COPUF (B/COPUF) gave the highest value of the normalized Pb I (405.7 nm) line intensity (2.3), followed by zeolite-modified COPUF (Z/COPUF) (1.9), and activated carbon-modified COPUF (AC/COPUF) (0.2), which indicates the adsorption performance of Pb2+ on the respective materials. The heavy metal ions’ adsorption on the B/COPUF dominantly resulted from the electrostatic attraction. This study demonstrated the potential use of B/COPUF in adsorption and LIBS quantitative analysis of aqueous heavy metal ions.

“…Gultom et al found that increasing zeolite had a positive influence on the mechanical properties of polyurethane nanocomposites. In particular, 20% of zeolite provided the PU nanocomposites the optimal mechanical behavior . Meanwhile, quite few related studies investigated the sound absorption and electromagnetic shielding effectiveness (EMSE) except for the combustion resistance.…”

Polyether polyol, isocyanate, and a flame retardant (10 wt%), zeolite (0 wt%, 1 wt%, 3 wt%, 5 wt%, 7 wt%, and 9 wt%) are used to form the rigid polyurethane (PU) foam, while a nylon nonwoven fabrics (400 g/m 2 ) and a polyester aluminum foil are combined to serve as the panel. The rigid PU foam and the panel are combined to form the rigid foam composites. The cell structure, compressive stress, combustion resistance, thermal stability, thermal conductivity, sound absorption, and electromagnetic shielding effectiveness (EMSE) of the rigid foam composites are evaluated, examining the effects of using flame retardant agent and zeolite. When the zeolite is 5 wt%, the rigid foam composites have an optimal density of 0.172 g/cm 3 , an average cell size of 0.2131 mm, a maximum compressive stress of 460.03Kpa, an optimal LOI of 28, and optimal EMSE of 40 dB, and the maximum thermal stability, thermal insulation, and sound absorption.
