Abstract
A process for producing olefins may include dehydrogenating a first alkane in a first reactor to produce a first effluent comprising at least one of a first n-olefin or a first diolefin; removing the first effluent from the first reactor; and regenerating the first reactor. The first reactor may include a first dehydrogenation catalyst and a first phase change material.
Claims18
A dehydrogenation reactor, comprising a reaction zone containing:
- a dehydrogenation catalyst;
- and
- a phase change material, wherein the phase change material undergoes a phase transition at a temperature of 525° C. or more and 675° C. or less, and wherein the phase change material comprises barium chloride and calcium chloride.
A dehydrogenation reaction system, comprising:
- a reactor comprising a fixed bed reaction zone containing first dehydrogenation catalyst particles disposed around sealed containers housing a first phase change material, wherein the sealed containers comprise sealed tubes that are spaced apart and arranged in a grid pattern within the fixed bed reaction zone.
A dehydrogenation reaction system, comprising:
- a reactor comprising a fixed bed reaction zone containing first dehydrogenation catalyst particles disposed around sealed containers housing a first phase change material, wherein the sealed containers are spaced apart and arranged in a grid pattern within the fixed bed reaction zone.
