In the present research, poisoning phenomenon of catalyst that applies for total oxidation process of volatile organic compounds (VOCs) has been studied. The VOCs emitted to workshop environment of printing industries from rapid drying of printed papers. Solvent of printing inks contain silica organic compounds that poisoned the catalyst. Pt/-Al2O3 catalyst is able to remove around 100% of organic pollutants in workshop atmosphere by total oxidation process. The process is carried out at the temperature more than 623K in a plug flow reactor. But poison, such as silica organic compounds, deactivates the catalyst so fast. Available laboratorial, pilot and industrial information were investigated and compared to understand the deactivation process, its main parameter(s), and scale up ability of data. Results showed that duration of process was the main parameter and prior to others.
