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.
Claims17
A process for producing olefins, the process comprising:
- 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,
- wherein the first reactor comprises 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;
- and
- wherein the dehydrogenation of the first alkane results in the temperature of the first phase change material to drop such that the first phase change material undergoes a phase transition.
