As a typical harmful VOC pollutant, benzene vapor is of great significance for its efficient purification treatment. Benzene vapor is a typical contaminant of VOCs which is the culprit of various diseases, so it is very meaningful to research how to purify the benzene vapor efficiently. Paper material is a kind of porous material with low density, high porosity and high mechanical strength. In this paper, two different kinds of paper, WFP (wood fiber paper) and CFP (ceramic fiber paper), are used as the porous substrates. Paper based silica gel adsorbent was made by gluing repeatedly, immersing the paper porous substrate in JN-30 silica sol and then drying them in oven several times. The surface morphology and structure of two kinds of paper materials were observed by the scanning electron microscopy (SEM). The adsorption properties of the samples which are made from WFP and CPF are tested by using the multi station absorption apparatus. The results show that the two porous substrates are of strong adhesive ability of silica, and the silica adhesive rate of the WFP and CFP reaches 3.38 g/g and 8.66 g/g after 6 times gluing. With the increase of gluing times, the silica adhesive rate of both materials is increasing, but after the gluing times reaches 4 times, growth of silica adhesive rate becomes significantly lower. The adsorption performance test results show the strong adsorption ability of the paper-based silica adsorbents on benzene vapor, both a good adsorption rate and adsorption capacity: it takes less than 30 min to achieve 80% of maximum adsorption capacity under 0.1 benzene vapor partial pressure, and the maximum adsorption capacity reaches 100 mg/g under 0.8 benzene vapor partial pressure. With the increase of the gluing times, the paper-based silica gel adsorbents’ adsorption capacity of benzene vapor first rises and then drop. In addition, the dynamic adsorption model of the paper-based silica gel adsorbents was fitted by the piecewise dynamic adsorption model. It was found that the dynamic adsorption process under the low pressure was divided into 2 stages: the early stage and later stage. In the early stage of adsorption, the adsorption capacity of materials is strong and adsorption quantity increases rapidly; in the later stage of adsorption, adsorption quantity increases much slower and gradually reaches saturation. By comparing isothermal adsorption curves of two different paper-based silica gel adsorbents, it can be found that, with the increase of gluing times, adsorption capacity of the WFP based silica gel adsorbents increases first and then decreases and it reaches the maximum at 4 times gluing. In contrast, the isothermal adsorption ability of CFP based silica gel adsorbents is basically unchanged after 4 times of gluing. Based on the fitting study of the adsorption isotherm with the Langmuir equation and the D-R equation, it was found that the adsorption isotherm was also divided into 2 parts: the low-pressure area and the high-pressure area. In addition, the adsorption characteristic curve is obtained by segmentation fitting the experimental results.
