Process for removing sulfur oxides from a gas
TL;DR: In this article, an absorbent consisting of free or combined lanthanum and alumina is used to remove sulfur oxides from a gas by a fluidized catalytic cracking process together with a hydrocarbon cracking catalyst to reduce sulfur oxide emissions from the regeneration zone.
Patent
Composition for removing sulfur oxides from a gas
TL;DR: In this paper, an absorbent comprising at least one inorganic oxide selected from the group consisting of the oxides of aluminum, magnesium, zinc, titanium, and calcium is recovered as a sulfur-containing gas comprising hydrogen sulfide by contacting the spent absorbent with a hydrocarbon in the presence of a catalycarbon cracking catalyst at a temperature from about 375° to about 900° C.
Patent
Removing sulfur oxides from a gas
TL;DR: Sulfur oxides were removed from a gas with absorbents and then are removed from the absorbents by contact with a hydrocarbon in the presence of a cracking catalyst as mentioned in this paper.
Patent
Catalyst for removing sulfur oxides from a gas
TL;DR: In this article, the ratio by weight of inorganic oxide or oxides to yttrium or yttium combined with a rare earth metal or metals is from about 0.1 to about 30,000.
Patent
Passivating metals on cracking catalysts with zinc
TL;DR: In this paper, a hydrocarbon cracking catalyst is treated with zinc to passivate contaminant metals, e.g., nickel, copper, vanadium, and iron, which are deposited on the catalyst during the catalytic cracking of hydrocarbon feedstocks.
