A process to make a sorbent composition said process comprising: (1) contacting (1.1) at least one zinc component, where said zinc component comprises zinc oxide, or a compound convertible to zinc oxide, (1.2) at least one silica component, where said silica component comprises silica, or a compound convertible to silica, (1.3) at least one colloidal oxide component, where said colloidal oxide component comprises a mixture that comprises a metal oxide, and optionally (1.4) at least one pore generator component; to form a first mixture; and thereafter, (2) extruding said first mixture to form an extruded, first mixture; and thereafter, (3) sphering said extruded, first mixture to form a sphered, extruded, first mixture that comprises particles where said particles have a particle size from about 0.5 to about 15 millimeters; and thereafter, (4) drying said sphered, extruded, first mixture to produce a dried, sphered, extruded, first mixture; or simultaneously therewith, or thereafter, (5) calcining said dried, sphered, extruded, first mixture to produce a calcined, dried, sphered, extruded, first mixture; and thereafter, (6) steaming said calcined, dried, sphered, extruded, first mixture, to form a steamed, calcined, dried, sphered, extruded, first mixture; and thereafter, (7) sulfiding said steamed, calcined, dried, sphered, extruded, first mixture, to form said sorbent composition. |
