Chemical manufacturing methods and chemical manufacturing equipment

Abstract

The method for manufacturing the chemical disclosed herein includes: supplying an inert gas into a reactor containing a flowing material with its length direction set as its height direction, causing the flowing material to flow; heating the flowing material to 780°C or higher; supplying the flowing material heated to 780°C or higher with a plastic-containing raw material; and recovering the chemical generated from the plastic-containing raw material, wherein the value X (cm3 / g / s) calculated by the following formula 1 satisfies X≤500, [Formula 1] X=V / (Gm+Pm) where, in Formula 1, V represents the total volume (cm3) inside the reactor, Gm represents the mass flow rate (g / s) of the inert gas, and Pm represents the mass flow rate (g / s) of the plastic-containing raw material.
