Catalytic conversion of DSO in presence of water

A catalytic conversion unit for the catalytic conversion in vapor phase of disulfide oil into methane and hydrogen sulfide, the catalytic conversion unit comprising a catalytic reactor comprising:

• a vapor feed line to feed the catalytic reactor with a vapor phase of disulfide oil,
• a gas recover line to recover a gaseous stream comprising methane and H2S, and
• at least one catalytic bed wherein a supported transition metal catalyst is placed,
• wherein the catalytic conversion unit further comprises:
• a vapor generator unit for generating the vapor phase of disulfide oil and fluidly connected to the vapor feed line of the catalytic reactor,
• a liquid feed line to feed the vapor generator unit with liquid disulfide oil, and a water reactor for providing liquid water or water steam to the catalytic conversion unit through a water line.
