Abstract
Official abstract text for this publication.
An object of the present invention is to prevent stress-corrosion cracking of a header ( 40 ) of a reactor. A reactor for producing trichlorosilane by causing metal silicon powder and a hydrogen chloride gas to react with each other includes a cooler ( 70 ), the cooler including a plurality of heat transfer medium pipes ( 30 ) and a header ( 40 ), the plurality of heat transfer medium pipes being provided in a fluid bed ( 60 ) inside the reactor, the header being provided in a freeboard section ( 50 ) inside the reactor, the header being comprised of a corrosion-resistant material.
First claim
Opening claim text (preview).
The invention claimed is: 1. A reactor for producing trichlorosilane by causing metal silicon powder and a hydrogen chloride gas to react with each other, comprising a cooler, the cooler including a plurality of heat transfer medium pipes and a header connected to the plurality of heat transfer medium pipes, the plurality of heat transfer medium pipes being provided in a fluid bed inside the reactor, the header being provided in a freeboard section inside the reactor, the header being comprised of a corrosion-resistant material, the corrosion-resistant material being Hastelloy C276, Hastelloy C22, or Inconel 600. 2. A method for producing trichlorosilane, comprising the step of producing trichlorosilane with use of a reactor recited in claim 1 . 3. The reactor of claim 1 , wherein the header is not in contact with the fluid bed. 4. The reactor of claim 1 , wherein the header is spaced from the fluid bed.
