Patent ID: 8657956

Claim:
A production apparatus for producing a solid product using a reaction of gaseous raw materials with a plurality of components using a vertical reactor disposed substantially in a vertical direction, comprising: a plurality of feed openings for gaseous raw materials provided on the upper part of the vertical reactor; a gas-feed opening for continuously feeding a seal gas with a density equal to or more than the density of the gaseous raw materials or the following exhaust gas to form a seal gas layer by the seal gas provided in the lower part of the vertical reactor; an exhaust opening for discharging an exhaust gas containing a by-product gas generated by the reaction and unreacted gaseous raw materials provided at a position above the uppermost surface of the formed seal gas layer; and a device for heating and feeding the seal gas provided to connect with the gas-feed opening for continuously feeding the seal gas, wherein the seal gas layer is provided with a linear velocity upward, which is maintained at a high value equal to or more than the velocity that prevents the exhaust gas from diffusion into the seal gas layer, and provided with a temperature gradient that the temperature of the lower layer part is low and the temperature of the upper layer part is high, a solid product is dropped and accommodated in the seal gas layer of the lower part, and the exhaust opening is disposed between the feed openings for gaseous raw materials and the gas-feed openings for continuously feeding the seal gas.
