Abstract
A regenerable sorbent for the removal of acid gas from a fluid stream. The regenerable sorbent is made from raw materials such as iron mineral, expansive clay and starch. Acid gas is removed from the fluid stream by a process where the raw materials are obtained, crushed, sifted, possibly pelletized, calcined and contacted with the fluid stream containing the acid gas.
Claims14
A composition for the removal of acid gas from a fluid stream, comprising:
- an iron mineral;
- an expansive clay comprising vermiculite;
- and, a starch, wherein the iron mineral comprises an iron oxide.
(canceled)
A process for the removal of acid gas from a fluid stream, comprising the steps of:
- crushing a composition comprising vermiculite and an iron mineral;
- sifting the crushed vermiculite and iron mineral composition;
- calcinating the crushed vermiculite and iron mineral composition;
- and,
- contacting the calcined vermiculite and iron mineral composition with the fluid stream.
