US 2025/0033019 A1 · REACTOR FOR OXYGEN-FREE DIRECT CONVERSION OF METHANE AND METHOD FOR PREPARING ETHYLENE USING THE SAME

Abstract

The present invention relates to a oxygen-free direct conversion of methane reactor and a method for producing ethylene using the same. More specifically, the invention provides a oxygen-free direct conversion of methane reactor and a method for producing ethylene from methane, wherein the reactor is selectively heated to save energy, prevent overheating with high responsiveness, and minimize coke formation, thereby achieving high methane conversion rate and high ethylene yield at a high reaction rate. The method also allows for the production of ethylene and aromatic compounds.

Dependent claims

An oxygen-free direct conversion of methane reactor comprising:

an inlet for introducing methane-containing feedstock;
a reaction section for reacting the methane-containing feedstock introduced from the inlet to produce ethylene-containing product;
and
an outlet for discharging the ethylene produced from the reaction section,
wherein the reaction section is made of FeCrAl alloy with an oxidation film formed on the inner surface, and a carbon layer is formed on the surface of the oxidation film of the FeCrAl alloy.
