Abstract

Official abstract text for this publication.

A reactor component according to an embodiment is used in a reactor that reacts a material to be treated in an environment where at least one of the material to be treated and an atmosphere contains sulfur or sulfide and is constituted of an alloy of which a principal component is Fe, which contains 13 to 35 percent by mass of Cr, and which contains a total of 0 to 35 percent by mass of Ni and Co.

First claim

Opening claim text (preview).

1 . A reactor component to be used in a reactor configured to react a material to be treated at a temperature equal to or higher than 300° C., wherein the reactor is configured to react the material to be treated in an environment where at least one of the material to be treated and an atmosphere contains sulfur or sulfide, and the reactor component is constituted of an alloy of which a principal component is Fe, which contains 13 to 35 percent by mass of Cr, and which contains a total of 0 to 35 percent by mass of Ni and Co. 2 . A reactor component to be used in a reactor configured to react a material to be treated at a temperature equal to or higher than 300° C., wherein the reactor is configured to react the material to be treated in an environment where at least one of the material to be treated and an atmosphere contains sulfur or sulfide, and the reactor component is constituted of an alloy of which a principal component is Ni or Co, which contains 13 to 35 percent by mass of Cr, and which contains a total of 35 to 87 percent by mass of Ni and Co. 3 . A reactor component to be used in a reactor configured to react a material to be treated at a temperature equal to or higher than 300° C., wherein the reactor is configured to react the material to be treated in an environment where at least one of the material to be treated and an atmosphere contains sulfur or sulfide, the reactor component is constituted of an alloy of which a principal component is Ni or Co, which contains less than 13 percent by mass of Cr, and which contains a total of 40 to 80 percent by mass of Ni and Co, and a coating film is formed on a surface of the alloy. 4 . The reactor component according to claim 3 , wherein the coating film is a ceramic film. 5 . The reactor component according to claim 4 , wherein the ceramic film has a thickness of 0.01 to 5 mm. 6 . The reactor component according to claim 3 , wherein the coating film is a metal plating film. 7 . The reactor component according to claim 1 , wherein the alloy contains one or more selected from the group consisting of W, Mo, Al, C, B, Si, Ti, Nb, Y, Hf, Zr, Ta, and Mn. 8 . The reactor component according to claim 1 , wherein the reactor component is a cylinder to which the material to be treated is supplied. 9 . The reactor component according to claim 8 , wherein the cylinder is configured to convey the material to be treated by rotating. 10 . The reactor component according to claim 1 , wherein the reactor component is a screw configured to convey the material to be treated by rotating. 11 . A reactor, comprising: a cylinder to which a material to be treated is supplied; and a heating apparatus configured to heat the cylinder, the reactor being configured to react the material to be treated at a high temperature equal to or higher than 300°° C., wherein the reactor is configured to react the material to be treated in an environment where at least one of the material to be treated and an atmosphere contains sulfur or sulfide, and the cylinder is constituted of an alloy of which a principal component is Fe, which contains 13 to 35 percent by mass of Cr, and which contains a total of 0 to 35 percent by mass of Ni and Co. 12 . A reactor, comprising: a cylinder to which a material to be treated is supplied; and a heating apparatus configured to heat the cylinder, the reactor being configured to react the material to be treated at a high temperature equal to or higher than 300° C., wherein the reactor is configured to react the material to be treated in an environment where at least one of the material to be treated and an atmosphere contains sulfur or sulfide, and the cylinder is constituted of an alloy of which a principal component is Ni or Co, which contains 13 to 35 percent by mass of Cr, and which contains a total of 35 to 87 percent by mass of Ni and Co. 13 . A reactor, comprising: a cylinder to which a material to be treated is supplied; and a heating apparatus configured to heat the cylinder, the reactor being configured to react the material to be treated at a high temperature equal to or higher than 300° C., wherein the reactor is configured to react the material to be treated in an environment where at least one of the material to be treated and an atmosphere contains sulfur or sulfide, the cylinder is constituted of an alloy of which a principal component is Ni or Co, which contains less than 13 percent by mass of Cr, and which contains a total of 40 to 80 percent by mass of Ni and Co, and a coating film is formed on a surface of the alloy. 14 . The reactor according to claim 13 , wherein the coating film is a ceramic film. 15 . The reactor according to claim 14 , wherein the ceramic film has a thickness of 0.01 to 5 mm. 16 . The reactor according to claim 13 , wherein the coating film is a metal plating film. 17 . The reactor according to claim 11 , wherein the alloy contains one or more selected from the group consisting of W, Mo, Al, C, B, Si, Ti, Nb, Y, Hf, Zr, Ta, and Mn.
