摘要:
A system employing a regenerable zinc-oxide based sorbent to remove one or more contaminants from an incoming gas stream. The contaminant-depleted gas stream can then be used for any subsequent application, while at least a portion of the contaminant-laden sorbent can be regenerated via a step-wise regeneration process. In one embodiment, sorbent regenerated via the step-wise regeneration process can comprise less sorbent-damaging compounds than traditional sorbents exposed to conventional regeneration processes.

摘要:
A process for the simultaneous removal of H2S and SO2 from tail gases is disclosed. A tail gas stream is contacted with a sorbent in a sorption zone to produce a product gas stream and a sulfur laden sorbent, wherein the sorbent comprises Zn and a promoter metal.

摘要:
A composition comprising a metal oxide and a promoter, wherein at least a portion of the promoter is present as a reduced valence promoter, and methods of preparing such composition are disclosed. The thus-obtained composition is employed in a desulfurization zone to remove sulfur from a hydrocarbon stream.
摘要:
A method for regenerating desulfurization sorbents that minimizes the in situ formation of one or more silicates. It has been discovered that regenerating sulfur-laden sorbent particles in a carbon oxide-rich environment unexpectedly reduces the in situ silicate formation rate, as compared to similar sorbents regenerated using conventional methods.

A method of making a composition, said method comprising, spraying a substance comprising platinum and iron into or onto an alumina-containing compound is disclosed. The resulting composition can then be used in a process for oxidizing carbon monoxide with free oxygen.
摘要:
Methods of oligomerizing hydrocarbons are disclosed. These methods include contacting olefins with an oligomerization catalyst in an oligomerization zone under oligomerization reaction conditions.
