Process for removing carbonaceous deposits on surfaces of catalysts and plant parts
摘要：
A process for removing carbonaceous deposits on surfaces of catalysts and plant parts by treating the deposits with a superheated stream of steam admixed at least temporarily with an oxygenous gas is provided, which involves, in each case monitoring the offgas CO2 content after condensation of the steam, at a temperature of at least 300° C.: (a) treating the carbonaceous deposits with superheated steam at a temperature of at least 300° C. until the CO2 content of the offgas has exceeded a maximum; (b) then, with further supply of superheated steam, commencing oxygen supply, the amount of oxygen supplied being adjusted such that the CO2 content in the offgas decreases further until it has fallen to a value of
摘要（中）：

提供了一种通过用至少暂时与氧气混合的过热蒸汽流处理沉积物来除去催化剂和植物部件表面上的碳质沉积物的方法，其包括在各种情况下监测蒸汽冷凝后的废气CO 2含量 ，在至少300℃的温度下：（a）在至少300℃的温度下用过热蒸汽处理碳质沉积物，直到废气的CO 2含量超过最大值; （b）然后，进一步供应过热蒸汽，开始供氧，调整供氧量，使得废气中的二氧化碳含量进一步下降，直到其下降到<1％体积的数值; 然后（c）结束过热蒸汽的供应并将氧气通过剩余量的碳质沉积物，直到沉积物被真实地除去。
