Consider the linear system Ax=b where the coefficient matrix A is an M-matrix. In the present work, it is proved that the rate of convergence of the Gauss-Seidel method is faster than the mixed-type splitting and AOR (SOR) iterative methods for solving M-matrix linear systems. Furthermore, we improve the rate of convergence of the mixed-type splitting iterative method by applying a preconditio...

Pervaporative desalination is an efficacious method to obtain fresh water from saline sources. High salt rejection and capacity cope with high-salt concentration solutions are important advantages of pervaporation process. To improve pervaporative performance, researches concentrate on novel membrane types. Water stable metal organic frameworks loaded membranes attract substantial attention amo...

Highly permselective and durable membrane materials have been sought for energy-efficient C3H6/C3H8 separation. Mixed-matrix membranes (MMMs) comprising a polymer matrix metal–organic frameworks (MOFs) are promising candidates this application; however, rational matching of filler-matrix is challenging their separation performances need to be further improved. Here, we propose novel strategy “d...

In this research, Polyether block amide (PEBA) containing different loadings of α-Al2O3 particles was deposited on top the polysulfone (PSf ) supports to form PEBA 1657‒α-Al2O3/PSf multilayer composite mixed matrix membranes (MCMMMs). Multilayer Composite structure used overcome sedimentation fillers in polymer matrix. Moreover, alpha phase Al2O3 applied improve distribution these at higher loa...

The gas separation performance of commercial ceramic Titania and hybrid silica (HybSi®) membranes was assessed using the gas permeation and permporometry methods. Results indicated that the HybSi® membranes have a hybrid surface containing regions covered by a polymeric matrix and others with inorganic pores. These membranes have high H2 selectivity, which incre...

The efficient separation of butadiene (1,3-C4H6) from C4 hydrocarbons is a critical step in petrochemical processes. However, the traditional cryogenic distillation suffers energy-intensity and serious environmental stress, necessitating development alternative technologies for 1,3-C4H6 separation. Herein, recognition mixed matrix membrane reported via incorporating metal copper encapsulated me...
