Abstract
The growing need for carbon dioxide (CO2) removal in various industrial sectors has led researchers to focus on the positive features of mixed matrix membranes (MMMs). Covalent triazine frameworks (CT-1) and polysulfone (PSF) were both used in the creation of MMMs. Due to the high porosity, significant area of surface, uniform dimension of pores, and thermal and chemical resistance, CT-1 was selected. The newly developed CT-1/PSF MMMs were prepared with different CT-1 loadings (0, 0.1, 0.3, 0.8, 1.1, and 1.5 wt %) in dope solution. The performance of membranes was evaluated using FTIR, FESEM, TGA, mechanical properties, and gas separation tests. In pure gas tests, the CO2 permeance and ideal CO2/N2 and CO2/CH4 selectivity increased when CT-1 loading was increased from 0 to 0.8 wt %. MMMs confirmed 109.12 and 91.42% increases in CO2/N2 and CO2/CH4 selectivities compared to pure PSF, respectively. However, a further increase in CT-1 loading beyond 0.8 wt % led to a drop in ideal selectivity. CO2 permeance and selectivity were reduced with pressure (2, 3, 4, and 5 bar). Additionally, investigated the effect of the feed stream (3/97 vol % of CO2/CH4) on CO2 separation. This paper describes a new technique for improving the ability of mixed matrix membranes through CT-1 fillers.
期刊介绍:
Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas.
Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
