| Abstract: | Processes are disclosed for removing sulfur, including cyclic
and polycyclic organic sulfur components such as thiophenes and
benzothiophenes, from a hydrocarbon feedstock including fuels and
fuel components. The feedstock is contacted with a regenerable
sorbent material capable of selectively adsorbing the sulfur
compounds present in the hydrocarbon feedstock in the absence of a
hydrodesulfurization catalyst. In one embodiment, the sorbent can
be an active metal oxide sulfur sorbent in combination with a
refractory inorganic oxide cracking catalyst support. In another
embodiment, the sorbent can be a metal-substituted refractory
inorganic oxide cracking catalyst wherein the metal is a metal
which is capable in its oxide form, of adsorption of reduced sulfur
compounds by conversion of the metal oxide to a metal sulfide. The
processes are preferably carried out in a transport bed
reactor. |
