Abstract
A reactor tube for a tubular reactor and a retaining device associated with the reactor tube; the reactor tube comprising an elongate tube defining a bore for receiving in use a catalyst and having an outlet at one end of the bore for discharging the catalyst out of the bore; the retaining device being configured to be rotatable between a first position and a second position; wherein in the first position the retaining device at least partially obstructs the outlet for retaining the catalyst within the bore; and in the second position the outlet is unobstructed sufficiently for permitting discharge of the catalyst out of the outlet.
Claims18
A reactor tube for a tubular reactor and a retaining device associated with the reactor tube;
- the reactor tube in the form of an elongate tube defining a bore for receiving in use a catalyst and having an outlet at one end of the bore for discharging the catalyst out of the bore;
- the retaining device being configured to be rotatable between a first position and a second position and rotatable about an axis that is parallel to, and non-coincident with, a longitudinal axis of the elongate tube;
- wherein in the first position the retaining device at least partially obstructs the outlet for retaining the catalyst within the bore;
- and
- in the second position the outlet is unobstructed sufficiently for permitting discharge of the catalyst out of the outlet.
A tubular reactor comprising a plurality of reactor tubes and a plurality of retaining devices;
- each reactor tube comprising an elongate tube defining a bore for receiving in use a catalyst and having an outlet at one end of the bore for discharging the catalyst out of the bore;
- each retaining device being associated with one or more reactor tubes and being configured to be rotatable between a first position and a second position and each retaining device is rotatable about an axis that is parallel to, and non-coincident with, the longitudinal axes of the elongate tubes;
- wherein in its first position each retaining device at least partially obstructs the outlet of one, some or all of its one or more associated reactor tubes for retaining the catalyst within the bore of one, some or all of its one or more associated reactor tubes;
- and
- in its second position the outlet of at least one of its one or more associated reactor tubes is unobstructed sufficiently for permitting discharge of the catalyst out of said outlet.
