| Abstract: |
| The paper aims to develop highly efficient regenerable meso-pore adsorption material with characteristics such as tightly closed, multi pollutant sources and complex composition, high temperature and high humidity for indoor air quality control on ship to solve selectivity and regeneration difficulty in the existing adsorption method. SBA-15 was used as a carrier to prepare mesoporous microporous adsorption material, on which metal oxide catalyst was loaded to prepare micro/mesoporous adsorption material. And the properties of the materials were studied with formaldehyde, toluene and alcohol as organic pollutant. The catalyst loaded meso-pore adsorption material reached the highest organic capacity when the catalyst content was 0.12%: 112.3 mg benzene/g catalyst, 119.7 mg toluene/g catalyst, 147.3 mg formaldehyde/g catalyst, 184.1 mg ethanol/g catalyst, which was 1.5 times more than the adsorption capacity of activated carbon. The adsorption capacity of organic matter after regeneration for 30 min was: 98.6 mg benzene/g catalyst, 106.3 mg toluene/g catalyst, 132 mg formaldehyde/g catalyst, 169.7 mg ethanol/g catalyst, illustrated its good regeneration performance. The pollutant concentration after treatment is lower than the Code for indoor environmental pollution control of civil building engineering (GB50325-2001). And the material could be efficiently regenerated and repeatedly used under high temperature and high humidity conditions. |
