20130137910 | Alkylation Process - The present invention provides an improved process for the catalytic conversion of a feedstock comprising an alkylatable aromatic compound and an alkylating agent to form a conversion product comprising the desired alkylaromatic compound by contacting said feedstock in at least partial liquid phase under catalytic conversion conditions with a catalyst composition comprising a porous crystalline material having a structure type of FAU, BEA* or MWW, or a mixture thereof, wherein the porous crystalline material has a Relative Activity measured at 220° C. as an RA | 05-30-2013 |
20130165724 | Fluid Bed Reactor with Staged Baffles - 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. | 06-27-2013 |
20150119619 | METHOD FOR PRODUCING ISOPROPYL BENZENE FROM BENZENE AND PROPYLENE - A method for producing isopropyl benzene includes the following steps. Step A: feeding a first stream containing benzene and a first stream containing propylene into a first reaction zone to contact a first catalyst for alkylation, and obtaining a first stream containing isopropyl benzene from the first reaction zone, dividing the first stream containing isopropyl benzene into a stream Ia and a stream IIa, the stream Ia circulating back into the first reaction zone and the stream IIa entering into a second reaction zone, having the stream entering the second reaction zone to contact a second catalyst for alkylation, and obtaining a second stream containing isopropyl benzene from the second reaction zone, and purifying at least a partial stream IIIa of the second stream containing isopropyl benzene, and obtaining a product isopropyl benzene. | 04-30-2015 |
