Embodiment 1
[0055] (1) Cuprous oxide (Cu) with a particle size of 0.1mm 2 O) powder and metal cerium dioxide (CeO) with a particle size of 0.1 mm 2 ) according to the mass ratio of 8:2, mix evenly, and fill to such as figure 1 In the shown ceramic tube with an inner diameter of 50 mm and a length of 800 mm, a barrier layer is provided at both ends of the ceramic tube, and the barrier layer is respectively provided with an air outlet and an air inlet;
[0056] (2) Put the sulfur-containing VOC gas (the composition is shown in Table 1) and the combustion-supporting gas oxygen into the ceramic tube through the inlet at a linear velocity of 1.2m / min, catalyze combustion at 680°C, and the exhaust gas after combustion flows out from the outlet. Finally absorbed by alkaline substances. The content of each component of VOC remaining in the exhaust gas is lower than the national air pollutant comprehensive discharge standard, as shown in Table 1.

Embodiment 2
[0061] (1) Copper oxide (CuO) powder with a particle size of 0.1 mm and aluminum oxide (Al 2 o 3 ) according to the mass ratio of 6:4, mix evenly, and fill to such as figure 1 In the shown ceramic tube with an inner diameter of 50 mm and a length of 800 mm, a barrier layer is provided at both ends of the ceramic tube, and the barrier layer is respectively provided with an air outlet and an air inlet;
[0062] (2) Put the sulfur-containing VOC gas (the composition is shown in Table 2) and the combustion-supporting gas oxygen into the ceramic tube through the inlet at a linear velocity of 1.2m / min, and catalyze combustion at 720°C, and the exhaust gas after combustion flows out from the outlet. Finally absorbed by alkaline substances. The content of each component of VOC remaining in the tail gas is lower than the national air pollutant comprehensive discharge standard, as shown in Table 2.
