Abstract
A Fischer Tropsch (“FT”) unit that includes an FT tube that is packed with a catalyst. The catalyst is designed to catalyze an FT reaction to produce a hydrocarbon. An insert that is positioned within the FT tube. The insert comprises at least one cross-piece that contacts an inner surface of the FT tube and at least one cross-fin extending from the cross-piece. There may be a corresponding second cross-fin adjacent each cross-fin. Both the cross-fins and the second cross-fins may be disposed radially outwardly such that the edge of the cross-fins are closer to the inner surface of the FT tube than is the base of the cross-fins.
Claims22
A Fischer Tropsch (“FT”) unit comprising:
- an FT tube;
- an insert that is positioned within the FT tube, the insert comprising:
- at least one cross-piece that contacts an inner surface of the FT tube;
- and
- wherein each cross-piece comprises a plurality of cross-fins along the cross-piece and extending from the cross-piece, wherein each cross-fin positioned closer to the FT tube is longer than each cross-fin positioned closer to a center of the insert.
An insert that is designed to be positioned within an Fischer Tropsch (“FT”) reactor tube, the insert comprising:
- three cross-pieces arranged to have dihedral symmetry;
- a plurality of cross-fins along each cross-piece and extending from the cross-piece, wherein each cross-fin positioned closer to the FT tube is longer than each cross-fin positioned closer to a center to the insert, wherein each cross-fin extends radially outwardly from the cross-piece such that the edge of the cross-fin is closer to the inner surface of the FT reactor tube than the base of the cross-fin.
