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.

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.

The improved process comprises maintaining a fluidized bed of regenerable acid solid medium pore zeolite catalyst particles in a turbulent regime reaction zone, preferably maintained with a superficial gas velocity of 0.1 to 1 meter/sec. with reformate feedstock being introduced at a bottom portion of the reaction zone at a weight hourly space velocity (WHSV) of 0.1 to 5, based on active catalyst solids; reaction zone total pressure being less than 2000 kPa. The preferred catalyst particles have an average particle size of 20 to 100 microns (.mu.), with about 10 to 25% of the catalyst particles comprising fine particles having a particle size less than 30 microns; and the preferred zeolite catalyst comprises shape selective medium pore aluminosilicate zeolite having a constraint index of 1 to 12. The benzene is reacted by contacting reformate feedstock, such as C.sub.6 distillation heart cut containing at least 70 wt % compounds having six carbon atoms, including benzene, n-hexane and isohexane, with said catalyst particles at reaction temperature of 370.degree. to 540.degree. C. and at benzene partial pressure of at least 200 kPa under reformate conversion conditions sufficient to convert at least 40% of feedstock benzene per pass, thereby producing a high octane fuel product containing less than 10 wt % C.sub.10.sup.+ components.

摘要： An olefin hydration catalyst is regenerated with a non-oxidizing light gas, such as hydrogen. Light olefins, especially propylene, are converted to a mixture of alcohol(s), such as isopropanol (IPA) and ether(s), such as diisopropylether (DIPE) by contacting a feed containing the olefin with water and/or alcohol with the olefin hydration catalyst. Regeneration conditions include temperatures of from about 150.degree. C. to about 550.degree. C., pressures below about 1000 psig (6900 kPa). Lower pressures of regeneration unexpectedly demonstrated more effective catalyst regeneration through greater coke removal.

摘要： A hydrodesulfurization process for catalytically hydrosulfurizing highly aromatic feeds, especially catalytically cracked feeds such as light cycle oils from catalytic cracking processes and aromatic extracts, employs a hydrodesulfurization catalyst containing zeolite beta. The zeolite beta based catalyst is more effective for effecting desulfurization than comparable amorphous catalysts or catalysts based on other large pore size zeolite and is capable of achieving a high degree of desulfurization at relatively low levels of conversion. The hydrodesulfurization catalyst comprises a transition metal hydrogenation component, preferably Co/Mo, on zeolite beta together with an inert matrix. The zeolite beta based catalyst may be mixed with amorphous catalyst such as Co/Mo/alumina. The low sulfur products are useful as blending components for road diesel fuels and other distillate fuels.
