摘要: Abstract A self-supporting ZSM-5 monolith with a hierarchical porosity was prepared using polyurethane foam (PUF) as structural template and hydrothermal synthesis procedure. The synthesized characterized investigated towards the adsorption catalytic oxidation of trichloroethylene (TCE). Adsorption TCE studied gravimetrically vapor-phase down-flow reactor. Monolithic displayed good sorption properties completely oxidized TCE. Conversion levels 50% 90% were achieved at reduced temperatures (by ∼50 °C) when compared conversion obtained from powder counterparts. Besides activity oxidation, it stable enhanced diffusion, thereby reducing pressure drops to great extent owing its porous nature.
