It has been carried out preparation of Chrom/Nanocomposite ZrO2-Pillared Bentonite catalyst with varying the amount of impregnating precursor at 0 to 3% (w/w). Material characterization of catalyst was carried out using X-ray Diffraction (XRD), X-ray Fluorescence (XRF), Infrared Spectroscopy (IR), Transmission Electron Microscope (TEM), Brunauer, Emmett, Teller (BET) and acidity measurement of ammonia-adsorption method. The results of research showed that pillarization was able to increase the basal spacing, surface area, diameter of pore and total volume of pore in catalyst, however increasing of impregnated Cr metal on bentonite caused the decreasing of basal spacing and surface area of catalyst but it would also caused the increasing amount of acid site. The experimental results showed that the catalyst could convert the castor oil into a liquid phase of 78.80% (w/w) with a biogasoline content of 32,73% (w/w).
The reduction of minor impurities (e.g., Ferrite, Magnesium, Lead, Chromium) from Zinc rich-EAFD with active carbon addition was investigated at temperature between 900-1300 °C. The result was powder with higher zinc content which then analysed by X-ray fluorescence spectroscopy (XRF), X-ray diffraction (XRD) and scanning electron microscope (SEM) equipped with X-Ray energy dispersive spectrometry (EDS). The thermogravimetry (TG) and differential thermal analysis (DTA) of EAFD and carbon mixture was conducted previously to grasp the temperature of thermic reaction of mixture. Recovery of 90wt% zinc from EAFD available was achieved up to 99.2wt% after the pyrometallurgy process at temperature 900 °C in atmosphere pressure while the extension of the time corresponds to the amount of recovered zinc dross.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
