Abstract
A process to produce a sorbent is provided. This process comprises: mixing a composition that comprises silica, a composition that comprises metal oxide, and a composition that comprises zinc oxide, to form a first mixture; and sphering said first mixture to form particles having a diameter from about 10 micrometers to about 1000 micrometers.

A process to produce a sorbent said process comprising producing spherical particles wherein said spherical particles are produced by the process consisting essentially of:
- (a) mixing
- (1) a composition that comprises silica,
- (2) a composition that comprises metal oxide dispersed in an aqueous medium, and
- (3) a composition that comprises zinc oxide to form a first mixture and then, without said first mixture being extruded;
- (b) sphering said first mixture to form particles having a diameter from about 10 micrometers to about 1000 micrometers.

A process to produce a sorbent said process comprising
- (a) producing spherical particles wherein said spherical particles are produced by the process consisting essentially of:
- mixing
- (1) a composition that comprises diatomaceous earth,
- (2) a composition that comprises aluminum oxide dispersed in an aqueous medium, and
- (3) a composition that comprises zinc oxide to form a first mixture and then, without said first mixture being extruded sphering said first mixture to form particles having a diameter from about 10 micrometers to about 1000 micrometers;
