Abstract
A loading sleeve and method for loading pellets into chemical reactor tubes where the length of the loading sleeve is greater than the clearance above the upper tube sheet. The loading sleeve includes a rigid upper sleeve portion and a rigid lower sleeve portion extending downwardly from the upper sleeve portion and means for holding the upper and lower sleeve portions together in both an aligned position, in which their longitudinal axes are aligned, and in an unaligned position, in which the longitudinal axes are at a substantial angle relative to each other. The method includes bending the loading sleeve at a hinge means, inserting the lower portion of the loading sleeve into the chemical reactor tube, then straightening the loading sleeve and inserting the upper sleeve portion into the chemical reactor tube.
