Abstract
A continuous process includes supplying, to a hydrogen production unit, an energy source in the form of mechanical energy or electrical energy produced from thermal energy generated in a hydrogenation process in a hydrogenation reactor unit, and flowing a light hydrocarbon feed stream into the hydrogen production unit in the presence of a catalyst to produce a hydrogen gas enriched stream using the energy source.
Claims20
A continuous process, comprising:
- supplying, to a hydrogen production unit, an energy source in the form of mechanical energy or electrical energy produced from thermal energy generated in a hydrogenation process in a hydrogenation reactor unit;
- and
- flowing a light hydrocarbon feed stream into the hydrogen production unit in the presence of a catalyst under reaction condition to produce a hydrogen gas enriched stream using the energy source.
A continuous process, comprising:
- hydrogenating, in a hydrogenation reactor unit, a liquid organic hydrogen carrier to a hydrogen-saturated liquid organic hydrogen carrier in the presence of a first hydrogen gas enriched stream and a hydrogenation catalyst;
- converting thermal energy generated in the hydrogenation reactor unit to an energy source in the form of mechanical energy or electrical energy;
- and
- supplying the energy source to a hydrogen production unit to convert a light hydrocarbon feed stream to a second hydrogen gas enriched stream.
