摘要: An alkene skeletal isomerization process is employed in an integrated process for the production of tertiary ether, e.g., tertiary amyl methyl ether (TAME) from the reaction of isoamylenes (iC.sub.5.sup.= 's) with methanol in the presence of an acid cation exchange resin. A light naphtha from a fluid catalytic cracking unit is used as the source of the iC.sub.5.sup.= 's in a process which separates the C.sub.5 containing fraction from the light naphtha, selectively hydrogenates the di-olefins contained in the C.sub.5 containing fraction, reacts the iC.sub.5.sup.= 's contained in the C.sub.5 containing fraction with methanol to form TAME, separates the TAME from the unreacted materials as a product, separates methanol from the unreacted materials, isomerizes a portion of the nC.sub.5.sup.= 's to iC.sub.5.sup.= 's , for example using a zeolite or an alumina treated with methanol, and use of the isomerization product as feed for a TAME reactor.

摘要: A process for the alkylation of benzene contained in a mixed refinery stream is disclosed wherein the refinery stream is first subjected to hydrogenation of higher olefins prior to alkylation of the benzene with selected types and quantities of lower olefins. Streams containing sulfur compounds may be pretreated by hydrodesulfurization. All of the process steps are advantageously carried out in distillation column reactors to take advantage of that mode of operation.

摘要: An internal static mixing system such as a disperser of mesh wire or expanded metal co-knit with a multi filament material selected from inert polymers, catalytic polymers, catalytic metals or mixtures in combination with a vertical reactor having a reaction zone and the disperser disposed in said reaction zone, particularly for carrying out paraffin alkylation using acid catalyst is disclosed. The wire mesh provides the structural integrity of the system as well as the open space required in reactors for the movement of vapors and liquids though the system. The disperser may be in sheets, bundles or bales or positioned within a frame.

摘要: A process for the alkylation of alkane with olefin or olefin precursor such as an oligomer of tertiary olefin comprising contacting a liquid system comprising acid catalyst, isoparaffin and olefin in concurrent downflow into contact in a reaction zone with a disperser mesh under conditions of temperature and pressure to react said isoparaffin and said olefin to produce an alkylate product is disclosed. Preferably, the liquid system is maintained at about its boiling point in the reaction zone. Unexpectedly, the olefin oligomers have been found to function as olefin precursors and not as olefins in the reaction. Thus, for example, a cold acid alkylation using an oligomer of isobutene (principally dimer and trimer) with isobutane produces isooctane with the isobutane reacting with the constituent isobutene units of the oligomers on a molar basis. The product isooctane is essentially the same as that produced in the conventional cold acid process.
