Abstract
A system for thermally decomposing chemical materials efficiently and controllably heats input feed materials to very high temperatures for decomposition in the presence or absence of oxygen by heating means that may be disposed peripherally or intermediately of reaction zones may be of the protected type and may include preheating of feed material and process gas.
Claims27
A thermal decomposition processor and system comprising
- means defining a reaction zone,
- heat means disposed in heat exchange relation to said reaction zone and having means for controllably supplying heat to or removing heat from said zone,
- said heat means including at least one heat generator physically separated from said reaction zone,
- means passing a feed material in gaseous, vaporized or finely divided form through said reaction zone for decomposition of said material,
- means defining a gas preheating zone for process gas, means directing preheated process gas into mixing relation to said feed material prior to passage through said reaction zone for passing preheated gas and mixed feed material through said reaction zone and
- outlet means for removing decomposed material from said reaction zone.
3 more elements
A thermal decomposition processor and system comprising
- means defining an elongated reaction zone and having walls that are substantially non-reactive with oxygen and highly reactive chemicals at very high temperatures,
- heating means disposed about said reaction zone exteriorly of the walls thereof and physically separated therefrom for raising the temperature of said reaction zone to very high temperatures, and controlling the temperature profile in the reaction zone
- means defining at least one preheating zone in heat conducting relation to at least said reaction zone and communicating with of said reaction zone,
- means passing feed material and/or a process gas through said reaction zone, and
- a packed bed disposed in at least one said reaction zone and said preheating zone,
- means passing at least one of either of said processing gas or said feed material through said preheating zone before passing through said reaction zone.
3 more elements
A thermal decomposition processor and system comprising
- means defining a reaction zone,
- means directing material to be decomposed into a first end of said reaction zone at a controllable rate,
- heat means disposed in heat exchange relation to said reaction zone and physically separated therefrom for raising the temperature of said zone to decomposition reaction temperatures of said material in said zone, and
- control means controlling said heat means to supply heat to and to remove heat from said reaction zone and selected portions thereof
- whereby said material is controllably decomposed in said reaction zone for removal from a second end of said reaction zone.
2 more elements
A thermal decomposition processor and system comprising
- means defining an elongated reaction zone,
- heat means disposed about said reaction zone for raising the temperature of said zone,
- means defining at least one preheating zone axially through said reaction zone and separated therefrom with communication therebetween at a first end of the reaction zone and a preheating zone,
- inlet means directing a process gas and material to be decomposed in gaseous or vaporized form into said preheating zone for passage therethrough into said reaction zone whereby said material undergoes decomposition reactions in said reaction zone for removal from a second end of said reaction zone.
1 more element
A thermal decomposition process and system comprising
- means defining a reaction zone,
- heating means disposed in heat transmission relation to said reaction zone and including at least one heat generator physically separated from said reaction zone,
- means defining at least one preheating zone communicating with said reaction zone,
- means passing a feed material in gaseous, vaporized or finely divided form through said preheating zone and then through said reaction zone for decomposition of said material,
- means defining a separate gas preheating zone for process gas, means directing process gas through said separate gas preheating zone and then into mixing relation with said feed material prior to passage through said reaction zone for passing preheated and mixed and material and gas through said reaction zone and
- outlet means for removing decomposed material from said reaction zone.
