Abstract

In this work, the efficacy of volatile organic compounds (VOCs), such as benzene, toluene, ethylbenzene, and xylene, for the removal of indoor air in a heterogeneous photo-Fenton catalytic semi pilot reactor was investigated at room temperature. Fe-zeolite socony mobil (ZSM)-5 was used as the adsorptive catalytic material, which was coated on the polyethylene tubes as a solid support. The response of Fe-ZSM-5 to UV dry irradiation was investigated in terms of VOC degradation from the indoor air. Different coating materials were tested in order to achieve better binding and less pore blockage. Scanning electron microscope (SEM) micrographs of the Fe-ZSM-5 coated tubes were used for the morphological analysis of the tubes. A complete modular semi pilot reactor (12.51 L) was designed to accommodate the Fe-ZSM-5 coated tubes and UV lamps for UV irradiation, in order to achieve the degradation for VOC and the regeneration of the catalytic material. After completion of the setup, the plant design parameters, such as the linear velocity, surface volume loading rate (SVL), and space retention time (SRT), were calculated.

Highlights

Many industries produce gaseous waste, which contains pollutants that are harmful for humans, animals, and the whole environment [1,2]

Summary

Introduction

Many industries produce gaseous waste, which contains pollutants that are harmful for humans, animals, and the whole environment [1,2] These pollutants cause a variety of problems. Apart from industries, the creation of almost all building construction and indoor furnishing materials requires an enormous amount of chemicals [3,4] All of these synthetic materials (from wall paint to nail polish) produce many different volatile organic compounds (VOCs), which act as pollutants. Some of these VOCs, such as benzene, toluene, and their derivatives, are already registered as cancer-causing materials, which are primarily present in our indoor air nowadays [3,5]. The indoor concentrations of several VOCs are 10 times higher than their concentrations outdoors [6]
