“…With the need for capital-avoiding technologies that can remove sulfur without significant octane loss and without high consumption of limited hydrogen supply, some novel non-HDS methodologies are rapidly developed and are moving toward commercial levels, i.e., adsorption process [3][4][5] and liquid-liquid extraction process [6,7]. 0376 Pervaporation technology has advanced significantly and has been applied in the fields of dehydration of solvents [8][9][10], removal of trace volatile organic substances from water [11,12] and more recently separation of organic-organic mixtures [13,14]. In this membrane-based unit operation process, permeation of permeants through the dense polymeric membranes follows a three-step course: sorption of permeating molecules into, diffusion through, and desorption out of the membrane.…”

“…The separation performance of the membranes was attractive, but preparation of the polymers involved complicated synthesis route. Formation of composite membranes, which possess stable porous substrates and thin selective layers, has been reported to exhibit improved membrane stability [33,34].…”

“…Formation of hydrogen bonds and ionic linkages induces variation in performance parameters [5,6]. Membrane performance can also be modified by using a porous substrate, which provides mechanical strength, feasibility of scale-up and long life [7][8][9]. The thickness of the active polymer layer will largely affect the performance of the membrane due to mass transfer resistance and the presence of the ultraporous substrate could help in reducing the thickness of the upper most active membrane layer to a minimum to achieve maximum throughput.…”
