A process to produce a sorbent composition is provided. This process comprises: (a) contacting a zinc component, an alumina component, and a dispersant component, to form a mixture; and then (b) spray drying said mixture to form particles; and then (c) contacting said particles with a zinc compound, wherein said zinc compound is zinc oxide, or it is a compound convertible to zinc oxide, to form a sorbent composition. A process to produce a particulate composition that comprises zinc aluminate is provided. This comprises: (a) contacting a zinc component, an alumina component, and a dispersant component, to form a mixture; and then (b) spray drying said mixture to form said particulate composition.

1. A process to produce a particulate composition that comprises zinc aluminate, where said particulate composition comprises particles that have a size from about 30 to about 1000 microns, said process comprising:(a) contacting (1) a zinc component, (2) an alumina component, and (3) a dispersant component, to form a mixture, where said mixture is capable of being spray dried; and then (b) spray drying said mixture to form particles; and then (c) calcining said particles to combine said zinc component and said alumina component to produce a particulate composition that comprises zinc aluminate, where said particulate composition comprises particles that have a size from about 30 to about 1000 microns and where said calcining is conducted at a temperature in the range of about 300.degree. C. to about 1200.degree. C. for a time in the range of about 0.5 to about 12 hours; wherein said zinc component is zinc oxide, or any other zinc compound, which can combine with said alumina component to form zinc aluminate during step (c), and wherein said alumina component comprises alumina, or aluminosilicate, where said alumina component can combine with said zinc component to form zinc aluminate during step (c), and wherein said dispersant component promotes the spray drying ability of said mixture.
