The objective was to evaluate the non-modified (CN) and calcined (CC) clinoptilolite as catalysts of the in-situ co-pyrolysis of Sargassum biomass and high-density polyethylene (HDPE). Both CN and CC were utilized to enhance the pyrolysis reactions, aiming to upgrade the quality of the resulting byproducts. The potential applications of these bypro...

Oxygenated compounds methane derivates like formaldehyde and methanol have become important primary chemicals in the manufacturing of various consumer products and chemical intermediates used in the petrochemical sector. This study investigates the catalytic conversion of methane over bimetallic particles supported on mordenite and alumina. Various...

Furfural is a promising fuel precursor molecule which can be transformed into valuable compounds through hydrogenation or oxidation; however, many furfural-based products have limited applications due to oxygenated carbon chains and unsaturated bonds. In this study, bimetallic catalysts with various Ni-WO3 contents, supported on ZSM-5 zeolite, were...

This work presents the formation of a stable 3D monolith based on manganese oxide for the adsorption of lithium from brine. The precursor phase was prepared by microwave‐assisted hydrothermal synthesis and a subsequent calcination process to achieve the desired crystalline phase LiMn2O4. The monolith was formed using additive manufacturing, which a...

In this research surface modified zeolites, Linde Type A and clinoptilolite, were used for the chromate ions uptake from aqueous solutions as well as its encapsulation through a vitrification process. The surface chemistry of zeolites was modified using a cationic surfactant hexadecyltrimethylammonium (HDTMA) to promote the capability of anions upt...

Natural mineral catalysts dolomite and clinoptilolite were evaluated in their calcined and non-calcined form for application in the catalytic in-situ pyrolysis of orange peel. Biomass pyrolysis improved when using calcined catalysts, with an increase in biogas yields (5.4 and 5.2% increase for dolomite and clinoptilolite, respectively), while non-c...

This work presents the hydrogenation of 2-methylfuran (2-MF) in gaseous fluid phase into a catalytic reactor in order to obtain products with good properties to be used as biofuel. Bimetallic nanoparticles were obtained by impregnation on Al2O3 from the classic catalytic metals used in hydrogenation reactions such as platinum and palladium, combine...

In this work, the desorption of furfural, which is a competitive intermediate during the production of biofuel and valuable aromatic compounds, was studied using pure alumina, as well as alumina impregnated with iron and platinum oxides both individually and in combination, using thermogravimetric analysis (TGA). The bimetallic sample exhibited the...
