Abstract

The invention discloses an industrial sulfur-containing waste gas modified carbon-based adsorbent and a preparation method thereof. A carbon-based adsorbent is put into a flowing industrial sulfur-containing waste gas modifier, heating treatment is carried out, and the industrial sulfur-containing waste gas modified carbon-based adsorbent is obtained. The invention further discloses application of the industrial sulfur-containing waste gas modified carbon-based adsorbent in flue gas demercuration and an application method of the industrial sulfur-containing waste gas modified carbon-based adsorbent. Compared with the prior art, by modifying the carbon-based adsorbent with the industrial sulfur-containing waste gas, the demercuration performance of the adsorbent is improved, the effect of treating waste with waste is achieved, desorption and recycling of mercury are achieved at the same time, the content of total mercury entering the atmosphere is reduced, and meanwhile waste of the valuable natural resource mercury is reduced.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a modified carbon-based adsorbent for industrial sulfur-containing waste gas and its preparation method and application. Background technique [0002] Mercury is a highly toxic heavy metal element that seriously threatens the natural environment and human health. Mercury becomes x , NO x After that, it is the fourth largest pollutant in the flue gas of coal-fired power plants. my country's current mercury emission standards for coal-fired power plants and cost-effective mercury removal technology are still far behind developed countries in the world. In 2011, the Special Policy Research Group (SPS Team) of the China Council for International Cooperation on Environment and Development suggested that the mercury emission limit for coal-fired thermal power generation currently implemented in my country should be further tightened: it will be revised to 3 μg / Nm ...
