- W2766403956 abstract "In the recent year, the presence of CO2 in atmosphere has been increased tremendously after industrial revolution and it has been projected that the temperature of atmosphere will be raised about 1.4 oC to 5.8 oC by 2100. Therefore, it is important to control the emission of CO2 from industries. On the other hands, it is well documented in the literature that membrane technology is preferred over the conventional technologies (i.e. adsorption, absorption and cryogenic) due to its advantages including reliability, operational simplicity, low capital cost and easy maintenance. Among the various types of membranes, hollow fiber mixed matrix membranes (HFMMMs) exhibits great potential for CO2 separation because they offer large surface area, low pressure drop, high pressure stability, high separation performance and easy scale up compared to flat sheet mixed matrix membranes (FSMMMs) and spiral wound mixed matrix membranes (SWMMMs). Thus, there have been numerous works where researchers incorporated various inorganic fillers (i.e. zeolites, carbon, metal organic frameworks (MOFs) etc.) into different types of polymeric materials for the fabrication of HFMMMs. Despite of significant progress made in the recent year; highlights on current trends, issues and transport models of HFMMMs in CO2/N2 and CO2/CH4 separation are very limited. Therefore, in the present review article, we focused on the performance and issues of various materials based HFMMMs for CO2/CH4 and CO2/N2 separation. Major features of this review are reflected in the following three aspects: (i) comprehensive study on the performance of HFMMMs for CO2/N2 and CO2/CH4 separation (ii) issues with the fabrication of HFMMMs in CO2/N2 and CO2/CH4 separation (iii) prediction of transport models for HFMMMs in gases separation. In the present review article, it has been observed that the MOF based HFMMMs showed higher CO2/N2 and CO2/CH4 separation performance compared to the zeolite, carbon and other fillers based HFMMMs. On the other hand, ZIF-8, ZIF-93 and amine functionalized MIL-based HFMMMs showed higher CO2/N2 and CO2/CH4 separation performance compared to other fillers based HFMMMs. Among MOF based HFMMMs, amine functionalized MIL based HFMMM showed great potential for CO2 separation from N2 and CH4. Furthermore, the present paper reviewed the different issues with fabrication of HFMMMs including dope fluid composition; bore fluid composition and spinning parameters. It has been found that the spinning parameters including, dope fluid flow rate, bore fluid flow rate, dry gap height, force convection gas flow rate, take up speed, jet–stretch ratio and draw ratio effects the morphology of membrane and thus, performance of HFMMMs in CO2 separation. Therefore, the achievement of optimum and proper value of spinning parameters during the fabrication of HFMMMs is also need to be explored to enhance the performance of the membranes. Besides, from the review work on the transport models used for HFMMMs in gases permeations, it has been concluded that modified Maxwell model and modified Pal model will be more appropriate model to study the transport behavior of gases through HFMMMs contains low and higher loading of fillers, respectively." @default.
