摘要： An improved continuous cyclic process for removing oxides of sulfur from a waste gas with a regenerable particulate adsorbent in which hot adsorbent particles pick up SOx in a first fluid transport riser, followed by separation of clean gas from sulfur-contained particles which are then recycled to a desorber in which they are contacted at elevated temperature with a mixture of reducing gas and water vapor for release of sulfur as hydrogen sulfide. The adsorbent particles are then recycled in the process. Means are provided for removing particulates in the waste gas.
摘要翻译：一种用可再生颗粒吸附剂从废气中除去硫的氧化物的改进的连续循环方法，其中热吸附剂颗粒在第一流体输送提升管中吸收SO x，然后将清洁气体从含硫颗粒中分离出来，然后再循环至解吸器，其中它们在升高的温度下与还原气体和水蒸汽的混合物接触以释放硫作为硫化氢。然后在该过程中再循环吸附剂颗粒。提供了用于去除废气中的微粒的装置。

摘要： Coke or coke and hydrogen production may increase when the Asphalt Residual Treating (ART) Process for removing metallic and carbonaceous contaminants from hydrocarbons is operated with feed stock containing impurities that result in the deposition on the solid particulate contact material of acidic metallic compounds such as heavy metal chlorides. Coke or coke and hydrogen production is reduced by charging ammonia or other fugitive basic nitrogen compounds to the system after burning coke from the circulating inventory of catalytically inert contact material and prior to selectively vaporizing incoming charge of feed stock in the presence of the hot regenerated contact material.
摘要翻译：当使用含有杂质的原料进行沥青残留处理（ART）处理从碳氢化合物除去金属和含碳污染物的工艺时，焦炭或焦炭和氢气的产生可能增加，导致沉积在酸性金属化合物如重质的固体颗粒接触材料金属氯化物在从循环库存的催化惰性接触材料中燃烧焦炭之后，并且在热再生接触存在下选择性蒸发进料量之前，将氨或其它短暂的碱性氮化合物加入到体系中，可以减少焦炭或焦炭和氢气产生材料。
