temperatures preferably less than approximately four hundred 400 u00b0 degrees c the process consists of two steps the first step is the removal of h 2 s co 2 and h 2 o from a sour natural gas stream and sorbent regeneration this step is accomplished using the concept of temperature swing adsorption the contaminants in the natural gas are adsorbed on molecular sieves in fluidized beds operated at low temperatures preferably between approximately twenty 20 u00b0 degrees c and approximately sixty 60 u00b0 degrees c the spent sorbent is circulated to a high temperature preferably between approximately one hundred 100 u00b0 degrees c and approximately three hundred 300 u00b0 degrees c fluidized bed regenerator and the gas stripped from the sorbent in the regenerator is used for sulfur and hydrogen recovery the second step is the conversion of h 2 s to elemental sulfur and hydrogen in a corona reactor at a temperature less than approximately four hundred 400 u00b0 degrees c the h 2 s co 2 and ch 4 from the regenerator will form the primary feed to a corona reactor recovery of elemental sulfur and hydrogen from h 2 s in a nonthermral plasma reactor is based primarily on the following reactions the emphasis is on the dissociation of h 2 s according to reaction 6 formation of sulfur occurs by reaction 7 reactions 8 and 9 are responsible for formation of hydrogen since the feed gas stream to the corona reactor consists of h 2 s and co 2 the following reaction can also take place.
