Appl. No.:

13/557605

Inventors:

Lu Han - Herndon VA, US
Rathna P. Davuluri - Fairfax VA, US
Christopher G. Smalley - Manassas VA, US

International Classification:

B01J 8/18

US Classification:

585447, 422140

Abstract:

The invention relates to a process of alkylating aromatic hydrocarbons, and more particularly a process of making paraxylene by alkylation of benzene and/or toluene with methanol and/or dimethyl ether, and to an apparatus for carrying out said process, the improvement comprising staged injection of one of the reactants, with the stages separated by structured packing so as to minimize at least one of gas phase back-mixing, by-pass phenomena, and gas bubble size.

Abstract:

A method for removing gas contaminants from flowing solids in a fluid catalytic cracking (FCC) process can include: catalytically cracking a hydrocarbon feedstock in the presence of a catalyst in a riser of a FCC unit to produce a hydrocarbon product; separating the hydrocarbon product from a spent catalyst to produce a hydrocarbon product stream; regenerating the spent catalyst in a regeneration gas comprising oxygen to produce a mixture comprising a regenerated catalyst and a gas contaminant at a first concentration; introducing a stripping gas and the mixture into a regenerated catalyst stripper to produce a regenerated catalyst stream comprising the regenerated catalyst, the stripping gas, and a gas contaminant at a second concentration that is reduced by 50% or greater as compared to the first concentration; and introducing the regenerated catalyst stream to the riser.
