Method for upgrading a hydrocarbon gas contatning a hydrocarbon and sulfur species by cracking against the regenerated sorbent Caldcron. A.

PCT Int. Appl. WO Yh 20. Y06 (Cl. CO7C4104). I I Jul 1996. U.S. Appl. 36.5, 911.7, 30 Dee lYY4, IO pp. Deals with the upgrading of a gas containing a hydrocarbon and a species of sultur hy the cracking of the gas against the regenerated sorbent. During regeneratron, the sorhent is heated by the exothermic reactions of carbon burn-off and sulfur oxidation. During cracking, the heat in the sorbent adsorbed from the exothermic reactions supplies at least a portion of the heat needed for cracking. The process is conducted under pressure with minimum degradation of the corbent and without conversion of the sorhent to a \ulfatc. The apparatus IO carry out the process includes a regeneration chamber with an oxidant inlet and gas outlet, a means for discharging the \orhent from the regeneration chamber to the cracking chamber, a cracking chamber with a hydrocarbon inlet port and upgraded gas outlet port, and a means for transporting the sorhent from the cracking chamber to the regeneration chamhcr.
