Delignified lignocellulosic biomass was functionalized with amine groups. Then, the pretreated lignin-free date pits cellulose and the amine-functionalized-date pits cellulose (0–5 wt%) were incorporated into a polysulfone polymer matrix to fabricate composite membranes. The amine groups give additional hydrogen bonding to those existing from the h...

Lignocellulosic biomass was delignified by combining physical and chemical pretreatment techniques. Then, a polysulfone-polyethylene glycol blend, which was compatible with the lignin-free biomass (0 wt% to 3.0 wt%), was used to fabricate composite membranes. The presence of hydroxyl groups after the pretreatment was evaluated via Fourier transform...

In this paper, a review of the compatibility of polymeric membranes with lignocellulosic biomass is presented. The structure and composition of lignocellulosic biomass which could enhance membrane fabrications are considered. However, strong cell walls and interchain hindrances have limited the commercial-scale applications of raw lignocellulosic b...

This review paper centers on recent development and progress in natural gas processing and separation using nanoparticles incorporated membranes. Development of mixed matrix membranes (MMMs) is to enhance the performance of polymer membranes for CO2 separation. Overview of natural gas is illustrated. Abridged versions of MMMs development using an i...

Side-chain alkylation of toluene with methanol to form styrene and ethylbenzene was studied over cesium ion-exchanged zeolite X (Cs-X) with various catalyst additives to find out effective catalyst systems for styrene formation as well as to elucidate the roles of the additives. Out of 13 types of additives examined, only ZnO exerted substantial po...
