Abstract
A method of attaching/detaching a catalytic unit according to an embodiment is a method of attaching/detaching a catalytic unit accommodated in a reactor housing of a catalytic reactor, including a step of passing the catalytic unit through a gas inlet formed at a top portion of the reactor housing to attach or detach the catalytic unit to or from the reactor housing having a cylindrical shape extending in a vertical direction and configured such that a gas having a gauge pressure of 0.2 Mpa or more is introduced thereto.
Claims1
A catalytic reactor, comprising:
- a plurality of catalytic units;
- a reactor housing having a cylindrical shape extending in a vertical direction, the reactor housing being configured such that a gas having a gauge pressure of 0.2 MPa or more is introduced into the reactor housing, the reactor housing having an inlet for the gas at a top portion, the reactor housing accommodating the catalytic units;
- and
- one or more hanging metal fittings disposed, inside the reactor housing, above the catalytic units, and radially outward of the inlet in a radial direction of the reactor housing,
- wherein
- each hanging metal fitting, of the one or more hanging metal fittings, is:
- disposed at the top portion of the reactor housing or at a peripheral wall of the reactor housing;
- and
- separated from an upper surface of an uppermost catalytic unit, among the plurality of catalytic units, in the vertical direction of the reactor housing.
