| 摘要 |
This invention deals with the upgrading of a gas containing a hydrocarbon and a species of sulfur by the cracking of the gas against the regenerated sorbent. During regeneration, the sorbent is heated by the exothermic reactions of carbon burn-off and sulfur oxidation. During cracking, the heat in the sorbent absorbed 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 sorbent and without conversion of the sorbent to a sulfate. The apparatus to carry out the process includes a regeneration chamber (A) with an oxidant inlet (14) and gas outlet (15), a means (13) for discharging the sorbent from the regeneration chamber to the cracking chamber, a cracking chamber (B) with a hydrocarbon inlet port (22) and upgraded gas outlet port (24), and a means (26) for transporting the sorbent from the cracking chamber to the regeneration chamber. |
