Monodisperse Pd nanocubes of 20 nm rib length and Pd nanospheres of 3 nm diameter deposited on corundum were used as efficient tool to reveal structure sensitivity of three-phase hydrogenations of unsaturated alcohols. For an olefin alcohol hydrogenation in the kinetic regime, surface (100) atoms...
Activity, selectivity and stability enhancements often observed in bimetallic catalysts make them an inseparable part of today’s chemical industry. However, it is usually problematic to understand the real interactions resulting in such improvements due to the lack of control over the bimetallic...
Bimetallicity is known to provide synergistic effects and improve catalytic performance of monometallic counterparts in a variety of applications. Conventional impregnation methods for supported catalyst preparation do not allow for the control of bimetallic nanoparticle structure or size, which...
Recently, considerable research has been conducted into solid-acid catalyzed carbonylation of dimethyl ether (DME) to methyl acetate (MeOAc), which can be further used for the iodine-free production of ethanol or acetic acid. The zeolite mordenite (H-MOR) is known as a potential catalyst but is...
Suppression of addition reactions of asphaltene model compound during hydrogenation with sulfided iron catalystDownload
A model compound is used to probe the chemical and physical behaviors of asphaltene. Hydrogenation reactions were conducted in a batch microreactor at 430℃, 13.9 MPa H2 for 30 min using a solution of 1,3,6,8-tetrahexylpyrene in tetralin. Sulfided iron was prepared on α-alumina, γ-alumina and...
Selective ring opening of naphthenic compounds is a preferred reaction to increase cetane number of fuels. Indan ring opening was studied using both structured and powdered catalysts. A structured support of Sintered Metal Fibers (SMF) filter materials (FeCrAl alloy) was surface-oxidized to form...
In this study, a new arranged catalyst support with distinct open pore morphology has been fabricated via thermal oxidation of an FeCrAl alloy with an aim to address mass transfer limitations that conventional supports have due to their internal porosity. Subsequent characterization tests...
Natural-gas fuelled catalytic heaters are commonly used in heating industrial space and remote location operations. Industrial units typically contain platinum that provides methane combustion at lower temperatures than non-catalytic burning. This work aimed to find a cost-efficient alternative...
Due to its low cost, abundance and lower emissions compared to gasoline and diesel, there is a resurgence of interest in using natural gas as a transportation fuel. However, although the combustion of natural gas produces comparably less greenhouse gases (GHGs) and pollutants, CH4 itself is a...
