چکیده
This study investigated carbon monoxide methanation with 15 %NiO doped SAPO-34 zeolite-supported catalysts. The support was produced by hydrothermal synthesis, and nickel oxide added to the impregnation surfactant-assisted method, dissolved in different solvents (water, ethanol, acetone, 1-propanol). Various characterization techniques, N2 physisorption, XRD, SEM, TEM, FTIR, were used determine physical properties of XRD analysis showed that synthesizing catalysts surfactant reduced crystallite size. average crystal sizes synthesized using methods are between 11.3-7.1 nm 8.9-7.1 nm, respectively. physisorption assisted method had higher surface areas among two preparation methods. It observed area catalyst increased as boiling point solvent increased. Scanning electron microscopy (SEM) exhibited particle size 1-propanol prepared 118 86 According results, surfactants cause produce smaller particles. CO studies highest conversion values reached Ni/SAPO-34 1- propanol other which gave 19.2% 21.1% methane at 375C, low formation rates most component adsorbed on surface, some converted methane.

Conclusions The application of the mixed monolayer approach to gold electrodes coated with highly organized long-chain hydrocarbon amphiphiles enables us a t this point to obtain complete blocking of the electrode, or, by controlling the adsorption conditions, to leave a certain amount of natural pinholes. Both cases are of considerable interest from an electrochemical point of view. In the pre...
متن کاملSynthesis of SAPO-34 catalysts via controlled crystal growth
Introduction SAPO-34 is a silicoaluminophosphate zeolite with 8-membered ring windows (~0.38nm) displaying chabazite structure. SAPO-34 is an efficient catalyst showing improved catalytic performance in reactions such as methanol conversion to olefins [1], oxidative dehydrogenation of propane [2], conversion of light alkenes [3]. Its catalytic properties are mainly attributed to its mild acidit...
متن کاملCO Hydrogenation over Alumina-Supported Sulfide Cluster Catalysts
Bimetallic Mo-Fe and Mo-Co sulfide clusters were anchored on AI,O, and used for CO hydrogenation. In addition to methane, significant amounts of dimethyl ether were produced. The reaction orders obtained from power rate laws for methanation indicated that the surfaces of the catalytic ensembles were not completely saturated by CO, in contrast to the observations for most conventional CO hydroge...
