Abstract:
1. A production method for producing a solid product using a reaction of gaseous raw materials with a plurality of components, comprising a step of conducting the reaction using a vertical reactor disposed substantially in a vertical direction; a step of feeding the gaseous raw materials with a plurality of components from the upper part of the vertical reactor; a step of, in the lower part of the vertical reactor, forming a seal gas layer composed of a seal gas having a density equal to or more than the density of the following exhaust gas and fed continuously from the lower part of the vertical reactor; a step of, along the uppermost surface of the formed seal gas layer, discharging an exhaust gas containing a by-product gas generated by the reaction and unreacted gaseous raw materials from the vertical reactor; and a step of accommodating a solid product in the seal gas layer of the lower part.
