The effect of temperature on hydrocarbon adsorption by diphenyldichlorosilane coated zeolite and its application in permeable reactive barriers in cold regions

Abstract

Zeolite was modified and characterized for its potential application in permeable reactive barriers tasked with fuel removal. Characterization was accomplished to compare the material structure before and after the modification process. Batch sorption tests were performed to detect hydrocarbon capture performance, and regeneration experiments were conducted to determine longevity. Adsorption isotherms and thermodynamics were studied to determine the mechanism of hydrocarbon capture. Diphenyldichlorosilane (DPDSCI), a unique reactive chlorosilane with two phenyl groups, was selected to coat the zeolite. The surface characterization results revealed that the modification was successful and the..
