The formation of SAPO-5 molecular sieves is studied under hydrothermal conditions in the presence a new templating agent, 1-benzyl-2,3-dimethylimidazolium hydroxide ([bzmIm]OH). syntheses were carried out by varying synthesis parameters, viz. crystallization temperature, heating time and reactants molar composition (SiO2, Al2O3, P2O5, [bzmIm]+, H2O) order to investigate role each parameter on S...

Different acid catalysts (silicoaluminophosphates (SAPOs) -34, −18, and − 11, HZSM-5 zeolite) were tested as components of In2O3-ZrO2/acid tandem in the direct synthesis light olefins by hydrogenation CO2, CO their mixture. The conversion yield selectivity evidence that presence large amount strongly acidic sites SAPO-34 favors extent reaction mechanism with methanol intermediate, minimizing se...

"> The effects of templating on the catalytic performance of SAPO-34 catalyst have been investigated in conversion of methanol to olefins. SAPO-34 <span style="font-size: 11pt; color: #000000; font-sty...

Despite the increasing interest in adsorption cooling and desalination systems, poor heat hence mass transfer adsorbent-bed (the core component) impedes efficient energy conversion at system level increases its physical footprint. In response, this paper numerically investigates overall enhancement of cum employing emerging copper foamed adsorbent beds advanced thermal performance coated with m...

In this work, Mordenite zeolite was successfully synthesized with Si/Al ratio of 18 in absence of organic template. The hydrothermal method was applied for synthesis under optimum conditions: 24 h synthesis time, 180°C temperature and 2 days aging time. The obtained zeolite was characterized by X-ray powder diffraction (XRD), Brunauer-Emmett-Teller (BET), X-ray fluorescence (XRF), Fourier Trans...
