    Abstract: An integrated process for lowering the pour point of Fischer-Tropsch derived wax which comprises (a) collecting separately from a Fischer-Tropsch unit a Fischer-Tropsch wax and a Fischer-Tropsch condensate; (b) pyrolyzing the Fischer-Tropsch wax in a thermal cracking zone under thermal cracking conditions pre-selected to achieve a cracking conversion of the paraffins molecules present in the Fischer-Tropsch wax of at least 10 percent; (c) recovering from the thermal cracking zone a low pour point Fischer-Tropsch derived wax and a Fischer-Tropsch derived overhead product; and (d) mixing at least a portion of the Fischer-Tropsch derived overhead product recovered in step (c) and at least a portion of the Fischer-Tropsch condensate collected in step (a) with at least a portion of the low pour point Fischer-Tropsch derived wax in the proper proportion to produce a Fischer-Tropsch derived waxy product having a pour point equal to or below about 40 degrees C.
