摘要:
A silicate-resistant sorbent composition, as well as a method of making and using the same, is provided. The sorbent composition generally comprises a support component comprising one or more silicate-resistant silica-containing components that have been treated one or more silicate-inhibiting metals. The inventors have discovered that sorbent compositions made and used according to embodiments the present invention exhibit a surprisingly low in situ silicate generation rate when exposed to oxidative regeneration conditions.
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. A process for the recovery of sulfur is also disclosed. A tail gas stream is contacted with a sorbent in a sorption zone to produce solid sulfur, wherein the sorbent comprises Zn and a promoter metal, wherein the promoter metal is manganese.

A process for the removal of contaminants from a gas stream is disclosed. A gas stream is contacted with a chlorine-containing compound to form a mixed gas stream. The mixed gas stream is then contacted with a sorbent in a sorption zone to produce a product gas stream and a sulfur laden sorbent, wherein the sorbent comprises zinc and a promoter metal.

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.

摘要:
A method of making a heterogenously supported catalyst useful in dimerization, oligomerization or polymerization is provided in which a catalyst precursor containing a metal and an aromatic group are alkylated onto an oligomeric support having at least one terminal unsaturated group by Friedel Crafts alkylation.
摘要:
The present method describes the absorbing and desorbing of a gaseous reactant on a solid reactant. The solid reactant is an ammonia salt selected from the group consisting of alkali ammonium salts, alkali ammonium earth salts or a combination thereof.
