Table 9.2.6 illustrates a typical range of products in the diesel range obtained by the
Catalytic Condensation process with SPA catalyst followed by hydrogenation. The
worst product is the heavy polymer from a C3–C4 gasoline operation. The other three
materials are products derived from propylene feeds: propylene tetramer (dodecene),
heavy polymer from a tetramer operation, and the entire feed to the tetramer rerun
distillation column.
