Catalytic conversion of DSO in presence of water

The present invention relates to a method for the catalytic conversion in vapor phase of disulfide oil into methane and hydrogen sulfide, comprising the step of contacting disulfide oil, eventually in the presence of water, with a supported transition metal catalyst.

PRODUCTION OF LINEAR ALPHA OLEFINS FROM ORGANIC SULFIDES

Embodiments of the disclosure provide a system and method for producing a linear alpha olefin. A disulfide, a hydrogen donating compound, and water are combined to produce a mixture. The mixture is introduced to a reactor operated at a pressure equal to or greater than 22.06 MPa and a temperature equal to or greater than 374 deg. C to produce an effluent stream. The effluent stream is separated to produce a product stream including the linear alpha olefin. The disulfide can be a compound of formula R—S—S—R′ where R is a first alkyl group having carbon atoms ranging from 1 to 12 and R′ is a second alkyl group having carbon atoms ranging from 5 to 12. The hydrogen donating compound can include a partially hydrogenated multi-ring aromatic compound.
