摘要： An advanced method for controlling a solid catalyst alkylation process has been developed. At multiple locations throughout the alkylation process including multiple locations within the reaction zone, on-line Raman spectroscopy is used to measure the concentration of alkene. Operating parameters are adjusted depending upon the concentration of alkene measured, or the conversion of alkene determined. Different operating parameters are adjusted depending upon the alkene concentration or conversion measured at different locations thus pairing a particular operating parameter with an ideal location for alkene measurement and control.

摘要： This invention deals with a process for converting aliphatic C.sub.2 -C.sub.6 hydrocarbons into C.sub.6.sup.+ aromatics and C.sub.3.sup.= /C.sub.4.sup.= olefins. The process involves combining dehydrocyclodimerization (DHCD) with dehydrogenation. Thus, the feedstream is first sent to a DHCD zone which produces an effluent stream which contains C.sub.6.sup.+ aromatics along with C.sub.1 -C.sub.5 hydrocarbons. This effluent stream is separated into a stream containing C.sub.1 -C.sub.4 hydrocarbons and one containing C.sub.6.sup.+ aromatics. The C.sub.1 -C.sub.4 containing stream is flowed to a dehydrogenation zone to produce C.sub.3.sup.= /C.sub.4.sup.= olefins.

摘要： A process is disclosed for the conversion of light aliphatic hydrocarbons such as propane into aromatic hydrocarbons and especially high purity benzene. The feed hydrocarbon is converted to aromatic hydrocarbons in a dehydrocyclodimerization zone. The product stream from the dehydrocyclodimerization zone which contains benzene, toluene, xylenes and C.sub.6 -C.sub.10 non-aromatics are separated into an overhead stream which contains the non-aromatic hydrocarbons and a small fraction of the benzene and a bottoms stream which contains the remainder of the benzene and other aromatic components. The overhead stream is then flowed to a conversion zone where the C.sub.6 -C.sub.7 non-aromatic hydrocarbons are cracked and the benzene is combined with the bottoms stream and further separated to give a high purity benzene product stream and a toluene, xylenes and C.sub.9 + product stream. The toluene, xylenes and C.sub.9 + product stream may further be separated into a toluene and xylenes product and a C.sub.9 + product stream.

摘要： A method and apparatus for alkylating an alkylation substrate with an alkylating agent in the presence of solid catalyst particles in a transport reactor is disclosed. Solid catalyst particles in the transport reactor effluent recirculate to the inlet of the transport reactor through one or more conduits. The rate through each conduit is regulated by fluid-controlled valves that use the alkylation substrate as the regulating fluid. This method and apparatus help ensure uniform or symmetric flow of catalyst from the effluent of the transport reactor to the bottom of the transport reactor. This method and apparatus also help ensure uniform or symmetric flow of alkylation substrate to the bottom of the transport reactor with minimal bypassing by the alkylating agent around of the transport reactor. This invention finds use in the production of motor fuels by the alkylation of liquid hydrocarbons in the presence of solid catalyst particles.

摘要： A solid catalyst alkylation process that wets catalyst particles with the alkylation substrate prior to introducing the catalyst particles to a liquid phase alkylation reactor is disclosed. A vapor stream from the wetting step that comprises the alkylation substrate and a reactor effluent stream comprising product alkylate and excess alkylation substrate are both passed to the product recovery zone, which recovers the alkylate product and recycles the alkylation substrate. Routing the vapor stream and the reactor effluent stream together to the product recovery zone minimizes pressure imbalances, ensures steady catalyst flow, and minimizes equipment costs. This process is applicable to alkylation processes that produce motor fuels.
