NOVELTY - The system comprises: a multi-zone fractional distillation column (1) comprising a vessel defining distillation zones and having a reactant stream inlet (15) positioned in a lower portion of the column, a distillate stream outlet (14) positioned in an upper portion of the column, and a product stream inlet (3) positioned in a lower portion of the column; a first catalytic redistribution reactor (6); a second catalytic redistribution reactor (6a); and a pump positioned downstream from the distillate stream outlet and upstream from the first and second catalytic redistribution reactors.    USE - The system is useful for producing silane and hydrohalosilanes (claimed) such as hydrochlorosilane, which is useful for producing solar-grade silicon used in the production of solar cells.    ADVANTAGE - The system produces silane and hydrohalosilanes with high purity in a stable and predictable manner, and allows the back-washing of the catalyst redistribution reactor using only the source material during the system operation without materially upsetting the operation of the distillation column.    DETAILED DESCRIPTION - The system comprises: a multi-zone fractional distillation column (1) comprising a vessel defining a set of distillation zones and having a reactant stream inlet (15) positioned in a lower portion of the column, a distillate stream outlet (14) positioned in an upper portion of the column, and a product stream inlet (3) positioned in a lower portion of the column; a first catalytic redistribution reactor (6) comprising a vessel defining a chamber, a first fixed-bed catalyst, and a set of four valves; a second catalytic redistribution reactor (6a) comprising a vessel defining a chamber, a second fixed-bed catalyst, and a set of four valves; and a pump positioned downstream from the distillate stream outlet and upstream from the first catalytic redistribution reactor and the second catalytic redistribution reactor. The vessel of the first catalytic redistribution reactor comprises a first reactor lower port positioned in a lower portion of the vessel and a first reactor upper port positioned in an upper portion of the vessel. The first fixed-bed catalyst is disposed within the chamber between the first reactor lower port and the first reactor upper port. The first reactor lower port is in fluid communication with the product stream inlet, and the first reactor upper port is in fluid communication with the distillate stream outlet when first and third valves of the first reactor are open and the second and fourth valves of the first reactor are closed. The first reactor lower port is in fluid communication with the distillate stream outlet and the first reactor upper port is in fluid communication with the product stream inlet when the second and fourth valves of the first reactor are open, and the first and third valves of the first reactor are closed. The vessel of the second catalytic redistribution reactor comprises a second reactor lower port positioned in a lower portion of the vessel, and a second reactor upper port positioned in an upper portion of the vessel. The second fixed-bed catalyst is disposed within the chamber between the second reactor lower port and the second reactor upper port. The second reactor lower port is in fluid communication with the product stream inlet, and the second reactor upper port is in fluid communication with the distillate stream outlet when first and third valves of the second reactor are open and the second and fourth valves of the second reactor are closed. The second reactor lower port is in fluid communication with the distillate stream outlet, and the second reactor upper port is in fluid communication with the product stream inlet when the second and fourth valves of the second reactor are open, and the first and third valves of the second reactor are closed. The system further comprises a cooling device (5) positioned downstream of the distillate stream outlet. The first and third valves are configured to provide a flow rate of the distillate that is at least 9-fold greater than the flow rate through the second and fourth valves. The fixed-bed catalyst in the first catalytic redistribution reactor and the second catalytic redistribution reactor is an ion-exchange resin. The ion-exchange resin comprises a set of particles differing in size. An INDEPENDENT CLAIM is included for a method for producing silane and hydrohalosilanes.
