摘要： A fuel processing system is operative to remove substantially all of the sulfur present in a logistic fuel stock supply. The fuel stock can be gasoline, diesel fuel, or other like fuels which contain relatively high levels of organic sulfur compounds such as mercaptans, sulfides, disulfides, and the like. The system is a part of a fuel cell power plant. The fuel stock supply is fed through a reformer where the fuel is converted to a hydrogen rich fuel which contains hydrogen sulfide. The hydrogen sulfide-containg reformer exhaust is passed through a sulfur scrubber, to which is added a small quantity of air, which scrubber removes substantially all of the sulfur in the exhaust stream by means of the Claus reaction. The desulfurizing step causes sulfur to deposit on the scrubber bed, which after a period of time, will prevent further sulfur from being removed from the reformer exhaust stream. The sulfur scrubber station is rejuvenated by passing a gas stream containing a relatively small amount (about 1% by volume) of carbon monoxide. The carbon monoxide is converted to carbonyl sulfide which is then burned in power plant burner so as to form sulfur dioxide in the power plant exhaust stream.
摘要翻译：燃料处理系统可操作以基本上除去物流燃料原料供应中存在的所有硫。燃料原料可以是含有比较高含量的有机硫化合物如硫醇，硫化物，二硫化物等的汽油，柴油燃料或其他类似的燃料。该系统是燃料电池发电厂的一部分。燃料库存供应通过重整器进料，其中燃料转化为含有硫化氢的富氢燃料。含硫化氢的重整器排气通过硫洗涤器，向其中加入少量空气，该洗涤器通过克劳斯反应基本上除去废气流中的所有硫。脱硫步骤使硫沉积在洗涤床上，洗涤床在一段时间之后将防止进一步的硫从重整器废气流中移出。通过使含有相对少量（约1体积％）的一氧化碳的气流通过硫洗涤塔来恢复。将一氧化碳转化为硫化羰，然后在发电厂燃烧器中燃烧，从而在发电厂废气流中形成二氧化硫。

摘要： Construction and operational costs of recovering the extract or raffinate product of a simulated moving bed adsorptive separation process units are reduced by employing a dividing wall column to perform the separation. The raffinate or extract stream is passed into the column at an intermediate point on the first side of the dividing wall, with the column delivering the adsorptive separation product as a sidedraw from the opposite side of the dividing wall. A stream of co-adsorbed impurity is removed as an overhead stream and desorbent is recovered as a net bottoms stream.

摘要： Novel sorbent systems for the desulfurization of cracked-gasoline are provided which are comprised of a bimetallic promotor on a particulate support such as that formed of zinc oxide and an inorganic or organic carrier. Such bimetallic promoters are formed of at least two metals of the group consisting of nickel, cobalt, iron, manganese, copper, zinc, molybdenum, tungsten, silver, tin, antimony and vanadium with the valence of same being reduced, preferably to zero. Processes for the production of such sorbents are provided wherein the sorbent is prepared from impregnated particulate supports or admixed to the support composite prior to particulation, drying, and calcination. Further disclosed is the use of such novel sorbents in the desulfurization of cracked-gasoline whereby there is achieved not only removal of sulfur but also an increase in the olefin retention in the desulfurized product. Such sorbents can also be utilized for the treatment of other sulfur-containing streams such as diesel fuels.
