摘要： A hydrocarbon feedstock is catalytically reformed to effect dehydrocyclization of paraffins in a process combination comprising a first reforming zone, a sulfur-removal zone containing a mixed reforming catalyst and sulfur sorbent comprising a manganese component to preclude sulfur from the feed to a second reforming zone. The process combination shows substantial benefits over prior art processes in achieving reforming-catalyst stability.

摘要： Hydrocarbon conversion processes having a susceptibility to coke formation on the internal surfaces of processing equipment are improved by inhibiting the formation of coke with the use of a glass bead treatment for the metal surfaces. After treating with ordinary glass bead cleaning methods, metal surfaces are found to inhibit coke formation. The glass bead treatment is easily performed and, therefore, offers advantages over other chemical treatments for the deposition of silica on reactor internals.

摘要： An improved dehydrocyclization process for the selective conversion of light hydrocarbons to aromatics is presented. The activity of a catalyst containing nonacidic L-zeolite is greatly enhanced by the addition of water, water precursors, or mixtures thereof to the reaction zone during the dehydrocyclization reaction. Addition of between 10 and 100 wt. ppm H.sub.2 O results in a higher product yield of aromatics with increased product octane.

摘要： A hydrocarbon feedstock is catalytically reformed in a sequence comprising a continuous-reforming zone, consisting essentially of a moving-bed catalytic reforming zone and continuous regeneration of catalyst particles, and a zeolitic-reforming zone containing a catalyst comprising a platinum-group metal and a nonacidic zeolite. The process combination permits higher severity, higher aromatics yields and/or increased throughput in the continuous-reforming zone, thus showing surprising benefits over prior-art processes, and is particularly useful in upgrading existing moving-bed reforming facilities with continuous catalyst regeneration.

摘要： A process combination is disclosed to selectively upgrade naphtha in a manner to obtain an aromatics-rich, low-olefin product from the combination. Preferably the naphtha is subjected to aromatization to obtain an aromatics concentrate which is upgraded by hydrogenation of olefins in the aromatics-rich stream. Olefin saturation is effected following separation of the major portion of hydrogen from the aromatics concentrate and before fractionation/stabilization for removal of light ends, with concomitant low saturation of aromatics and with removal of light ends in a fractionator which would be associated with the aromatization in any case.
