IS THERE DIRECT OXIDATON OF H_2S TO SULFUR?

摘要

ConocoPhillips SPOC™ performance appears to demonstrate Claus reaction behavior versus direct oxidation. A slightly different view of Claus chemistry is used to propose a partial oxidation (POX) mechanism. In addition to describing sulfur/hydrogen yield in the POX reaction, the proposed Claus intermediates are used to describe potential mechanisms for ammonia destruction, non-hydrolysis COS and CS_2 conversion, and H_2S_x in liquid sulfur.
