    摘要: A low sulfur gasoline of relatively high octane number is produced from a catalytically cracked, sulfur-containing naphtha by hydrodesulfurization followed by octane enhancing treatment in a fluidized bed catalytic process, in the presence of an aromatics-rich feedstream. The process converts the hydrodesulfurized intermediate and the aromatics-rich feedstream to a gasoline boiling range fraction of high octane number. The fluidized bed catalytic process is carried out over zeolite catalyst particles in a turbulent reactor bed at a temperature of about 600.degree. to 800.degree. F. (316.degree. to 427.degree. C.) and pressure of about 100 to 250 psig (790 to 825 kPa. The catalyst has an apparent particle density of about 0.9 to 1.6 g/cm.sup.3 and a size range of about 1 to 150 microns, and average catalyst particle size of about 20 to 100 microns containing about 10 to 25 weight percent of fine particles having a particle size less than 32 microns. The feed vapor is passed upwardly through the fluidized catalyst bed under turbulent flow conditions; turbulent fluidized bed conditions are maintained through the reactor bed between transition velocity and transport velocity at a superficial fluid velocity of about 0.3 to 2 meters per second. Treatment in the fluidized bed catalytic process restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha.

    摘要: A benzene-rich gasoline stream is alkylated with higher olefins in contact with a fluid bed of shape selective zeolite catalyst to produce a gasoline product stream reduced in benzene content wherein the high octane value alkylaromatics formed by benzene alkylation are of low carbon number, essentially C10-. Concurrently, a portion of olefins in the gasoline stream are converted to gasoline boiling range hydrocarbons and the sulfur content of the gasoline feedstream is lowered. Besides enhancing the octane value of the feedstream, the process results in a lower Reid vapor pressure and lower sulfur content.

    摘要: A process for upgrading low octane naphthas to produce gasoline products with low levels of benzene and aromatics while retaining a high pool octane uses a paraffinic naphtha reformer feed which is dehexanized to provide a C.sub.7 + fraction which is fed to the reformer and a C.sub.6 fraction which is fed together with the C.sub.6 fraction from the reformer effluent to a catalytic upgrading step where the low octane components from the naphtha and the benzene from the reformate are converted to a low benzene, high octane gasoline by alkylation of the benzene and other aromatics present in the reformate. The process has the advantage that benzene make in the reformer is reduced by the partial by-passing of the C.sub.6 benzene precursors around the reformer; in addition, improved benzene alkylation results from the presence of additional light olefins generated by the cracking of paraffins from the paraffinic naphtha. the reaction is preferably carried out in a turbulent fluidized bed reaction zone.
