Cerium-based adsorbent activity detection method

Abstract

The invention relates to a cerium-based adsorbent activity detection method, which comprises the following steps: S1, injecting a cerium-based adsorbent into a desulfurization detection chamber through a feed port, and carrying out desulfurization adsorption on to-be-desulfurized gas injected into the desulfurization detection chamber through a gas inlet; S2, after a first preset time, enabling a central control unit to open an exhaust valve, and injecting the desulfurized gas into a sulfur content detection chamber for desulfurization amount detection; s3, pushing the cerium-based adsorbent in the desulfurization detection chamber into a regeneration chamber through a first power device to regenerate the cerium-based adsorbent, after a second preset time, filtering steam in the regeneration chamber, injecting the filtered steam into the elemental sulfur detection chamber to detect the elemental sulfur generation amount, injecting the regenerated cerium-based adsorbent into the desulfurization detection chamber, and repeating the steps S1 to S2; s4, enabling the central control unit to obtain the desulfurization performance of the cerium-based adsorbent according to the desulfurization amount and the regeneration capacity of the cerium-based adsorbent; enabling the central control unit to compare the obtained desulfurization performance of the cerium-based adsorbent with a preset value, and judge the adsorption activity of the current cerium-based adsorbent.

Description

technical field [0001] The invention relates to the field of detection, in particular to a detection method based on cerium-based adsorbent activity. Background technique [0002] Coal contains sulfur, so sulfur-containing tail gas is usually produced during the consumption of coal. In the process of traditional thermal power generation, the combustion of coal will produce SO 2 flue gas, while in the traditional coal chemical industry (such as coal gasification and coking), coal usually produces H in the process of being utilized 2 S gas. For the coal chemical industry, the H in the tail gas 2 S not only corrodes process equipment operated at high temperature, but also seriously pollutes the environment. Therefore, it is necessary to desulfurize and purify coal gas, and desulfurization technology has a great role and market in the entire field of coal utilization. The existing desulfurization technology mainly uses solid adsorbents to remove sulfur elements. Usually, af...
