The main objective was to synthesize in the laboratory and characterize the molecular sieve MCM-41. This study has a strong experimental character. The hydrothermal synthesis was performed at 100 ° C for a period of 7 days. The resulting materials were characterized by XRD, EDX, Adsorption Capacity and the Foster Swelling test. Through XRD verified the formation of mesoporous structure. Different organic solvents, namely gasoline, diesel and kerosene were used. The Foster Swelling Test results indicated that the affinity of molecular sieve MCM-41 occurred in the treated clay tested in all organic solvents (gasoline, diesel, kerosene), without and with agitation.
Cationic surfactants, such as quaternary ammonium cations, have been used, in order to ameliorate the oil sorption capacity of inorganics materials, such as clays. Clays modified with quaternary ammonium cations (organoclays) have better performance in sorption, remove oil and grease from water at seven times the rate of activated carbon, as well as they can be used like perforation fluids of oil wells to the oil base, lubricants, among others industries. This work aims characterize the Cloisite 30B using various techniques: X-Ray Diffraction (XRD), Specific Surface Area (BET) and Cation Exchange Capacity. Different organic solvents, namely gasoline, diesel and kerosene were used in order to investigate the clays compatibility after orgophilization.
The zeolites differ from traditional adsorbents for selective adsorption of small molecules, the high adsorption capacity at low concentrations and affinity for organic compounds and unsaturated polar molecules. In this work a Y-type zeolite was synthesized, characterized by x-ray diffraction, scanning electron microscopy and adsorption of nitrogen and subjected to test adsorption capacity where it was found that the Y zeolite has the potential adsorption capacity compared to other materials being studied and marketed.
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.
