Chemical manufacturing methods and chemical manufacturing equipment

Abstract

The method for manufacturing the chemical disclosed herein includes: heating a fixed-bed reaction section having a packing layer filled with packing material; and thermally decomposing a raw material containing plastic in the fixed-bed reaction section in the presence of an inert gas, wherein, during the thermal decomposition, the gas space velocity (GHSV) of the inert gas in the packing layer, as determined by Equation 1 below, is 5,000 h⁻¹ or more. [Equation 1] GHSV = Q / V Wherein, in Equation 1, GHSV represents the gas space velocity (h⁻¹) of the inert gas in the packing layer, Q represents the flow rate of the inert gas (Nm³ / h), and V represents the volume (m³) of the packing material in the packing layer.
