Abstract Developing an economically viable and eco‐friendly catalyst is essential for the dehydrogenation reaction. In this context, cobalt‐based catalysts supported on different morphologies of γ‐Al 2 O 3 , nano‐sheet (Al −NS), nano‐fiber −NF) nano‐plate −NP) were synthesized using wetness impregnation method tested non‐oxidative propane Metal support interaction Lewis acidic center play a crucial role in reaction; therefore study focuses investigating these parameters catalytic activity...
Propane dehydrogenation is a highly efficient and selective route to produce propylene. The development of transition-metal-based catalysts, especially cobalt oxide–Co(II) for propane reaction has gained momentum in the past few years. However, formation bulk metallic major drawback oxide-based which need be circumvented maintain high propylene selectivity. In this study, facile proposed prepare stable Co(II) on mesoporous silica matrix (Co-mSiO2) via simple synthesis procedure using neutral...

Abstract SAPO‐34 hollow fiber zeolite membranes are successfully synthesized on α‐Al 2 O 3 ceramic substrates by secondary growth method, and used to separate H from a binary mixture (H , C 8 ) or ternary 6 under wide temperature range (25–600°C) with the aim of using them for propane dehydrogenation (PDH) reactions at high temperature. The results show excellent performance /C / & separation, permeance 3.1 × 10 −7 mol/m /s/Pa selectivity 41 600°C. Additionally, membrane shows stable 140...
Pd-based membranes are used for separation of H2 from different feed stocks; however, their application is limited in the presence hydrocarbons due to coke deposition on membrane surface under operation conditions. Herein, we have developed a triple-layered with nanoporous Linde type A zeolite outer side and an ultrathin (1 μm) Pd inner Al2O3 hollow fiber substrate. The was successfully synthesized tested hydrogen lighter hydrocarbons. uniform nanosize pores layer acts as barrier come...
The hydrogen isotope effect on the thermodynamic and kinetics of hydrogen/deuterium absorption–desorption in a single-phase ternary alloy Pd0.77Ag0.10Cu0.13 having fcc crystal structure was investigated using Sievert-type volumetric apparatus to explore its viability for use room-temperature self-displacement gas chromatography (SDGC) separation isotopes. Desorption pressure–composition isotherms (PCIs) were measured temperature range 313–393 K, absorption reaction studied isochoric...
Abstract Catalytic dehydrogenation of saturated hydrocarbons to corresponding alkenes by the release stoichiometric amount hydrogen is paramount solution for safe storage hydrogen. The utilization a catalytic membrane reactor this process enhances reaction yield beyond thermodynamic equilibrium selectively and simultaneously removing produced H 2 during reaction. To end, present review focused on integration permeable membranes with catalysts lighter alkanes coproduction olefins high-purity...
Abstract Titanium‐Iron alloy is a well‐known material for hydrogen storage applications at room temperature. The limitations of TiFe its low capacity, higher activation temperature, and pressure. In order to improve the adsorption alloy, clusters with Zr atom as dopant are investigated using first‐principle calculations. structure Zr‐substituted unsubstituted was optimized it found that binding energy than clusters, thus, doping stabilizes clusters. Hydrogen over doped cluster investigated,...
