    摘要： A process for desulphurization of a gaseous substrate containing O 2 , SO 2 , SO 3 , H 2 , SO 4 , H 2 S, CS 2 , COS and/or organic sulphur-containing components. The combustible components are oxidized catalytically into H 2 O, CO 2 , and SO 2 . The SO 2 is further oxidized catalytically into SO 3 , which in presence in the substrate of at least an equivalent amount of H 2 O in the gas, is further hydrated and condensed as sulphuric acid. The process is conducted in two reactors that are connected in series, each reactor being loaded with a layer of inert material below a layer of oxidation catalyst. The process includes reversing a direction of gas flow in the reactors after periods of about 1-40 minutes. The temperature in layers of the oxidation catalyst in the reactors is maintained in a range of 300-500 o C. The temperature of the gas stream leaving the reactors is at least 50 o C below the H 2 SO 4 dew point of the process gas after oxidation of the sulphur content in the feed gas. Condensed sulphuric acid is drained off from the bottom of each of the reactors.

    摘要翻译： 一种含有O 2，SO 2，SO 3，H 2，SO 4，H 2 S，CS 2，COS和/或有机含硫组分的气态底物脱硫的方法。 可燃组分被氧化催化成H 2 O，CO 2和SO 2。 SO 2进一步被氧化氧化成SO 3，其在气体中至少相当量的H 2 O的底物存在下进一步水合并浓缩为硫酸。 该方法在串联连接的两个反应器中进行，每个反应器在氧化催化剂层下方装载一层惰性材料。 该方法包括在约1-40分钟的时间段之后反转反应器中的气流的方向。 反应器中的氧化催化剂层的温度保持在300-500℃的范围内。 在进料气中硫含量氧化后，离开反应器的气流的温度比工艺气体的H 2 SO 4露点低至少50℃。 冷凝硫酸从每个反应器的底部排出。

    摘要： Process for the separation of sulphur oxides from offgases, comprising the steps of passing at a temperature from 250 DEG C to 400 DEG C the sulphur oxides containing offgas through a fixed bed of a sulphur oxide adsorbent, having catalytic activity in the oxidation of sulphur oxides to sulphur trioxide and comprising supported on a porous carrier a mixture of vanadium pentoxide and pyrosulphates of one or more alkalimetals; adsorbing and converting on the adsorbent sulphur oxides to sulphur trioxide; regenerating the sulphur trioxide loaded adsorbent with air at a temperature from 500 DEG C to 650 DEG C; recirculating a part of the regeneration air to the fixed bed of the adsorbent; and finally removing desorbed sulphur trioxide in the regeneration air by hydration of the desorbed sulphur trioxide to sulphuric acid and condensing the sulphuric acid in a sulphuric acid condenser.
