Abstract: A solar reactor useful in reaction processes, more particularly, useful in endothermic reaction processes, such as a catalyzed process or an adsorption-desorption process. The reactor comprises a reaction pathway defined by an exterior wall and an interior wall, the exterior wall comprising a solar radiation receiver capable of converting solar radiation into heat and transmitting the heat to the reaction pathway. The reaction pathway has disposed therein, in alternating fashion, a plurality of reactive elements comprised of a catalyst or a sorbent and a plurality of heat transfer elements.

Abstract: A process of producing ethylene involving steam cracking ethane to produce a steam cracker product stream containing ethylene; cooling and drying the steam cracker product stream; contacting the cooled and dried steam cracker product stream with a MOF sorbent capable of adsorbing ethylene from the product stream, and desorbing the ethylene from the MOF sorbent using an ethylene sweep gas. The process replaces complex and energy intensive fractionation steps of the prior art with a selective adsorption step for separating ethylene from the steam cracker product stream. An energy efficient ethylene sorbent regeneration method and related apparatus systems are also disclosed.

Abstract: A catalytic solar reactor useful in chemical processes, more particularly, useful in endothermic chemical processes. The reactor comprises a reaction pathway defined by an exterior wall and an interior wall, the exterior wall comprising a solar radiation receiver capable of converting solar radiation into heat and transmitting the heat to the reaction pathway. Further, the reaction pathway has disposed therein, in alternating fashion, a plurality of catalytic elements and a plurality of heat transfer elements. Optionally, a supplementary heater, such as a conventional fossil fuel burner, is disposed in a plenum located within the interior of the reactor. The heater is employed as a supplemental source of heat, for example, when solar radiation is unavailable.

Abstract: A catalytic reactor constructed of a thermally conductive housing defining a reaction zone having disposed therein: (a) a plurality of catalytic elements, each comprising a porous material having a catalyst supported thereon, and (b) a plurality of heat transfer elements, each comprising a porous, thermally conductive, and essentially catalytically inactive material; wherein the plurality of catalytic elements and the plurality of heat transfer elements are disposed in an alternating configuration within the reaction zone. The catalytic reactor is useful in chemical reactions where heat transfer is a rate limiting step.
