Abstract
Designs for electrically heated reactors are disclosed. In one embodiment, a cylindrical reactor design to provide high temperature heat for an endothermic steam methane reformer without combustion includes: a cylindrical shell, one or more parallel internal cylindrical return tubes, baffles perpendicular to the axis of the shell, electrical heating elements disposed parallel to the shell axis and arranged in one or more rings extending through one or more baffles, and fitted with annular gas entrance and cylindrical gas outlet plena attached to one end of the device.
Claims12
An apparatus for conducting an endothermic reaction in a feed fluid in a cylindrical reaction plenum extending about an axis, the apparatus comprising:
- a shell configured to bound the cylindrical reaction plenum;
- a first discoidal baffle providing a first feed fluid flow passage therethrough, the first discoidal baffle being arranged to be diametrically perpendicular to the axis of the cylindrical reaction plenum within the cylindrical reaction plenum and to position the first feed fluid flow passage within the cylindrical reaction plenum;
- a second discoidal baffle providing a second feed fluid flow passage therethrough, the second discoidal baffle being arranged to be diametrically perpendicular to the axis of the cylindrical reaction plenum within the cylindrical reaction plenum and to radially offset the second feed fluid flow passage from the first feed fluid flow passage within the cylindrical reaction plenum relative to the axis of the cylindrical reaction plenum;
- a cylindrical return tube arranged to extend, within the cylindrical reaction plenum, parallelly to the axis thereof, and in fluid communication therewith, through the first discoidal baffle and the second discoidal baffle;
- and
- an electric heating element arranged to extend, within the cylindrical reaction plenum and parallelly to the axis thereof, at least from one of the first discoidal baffle and the second discoidal baffle toward another of the first discoidal baffle and the second discoidal baffle.
