An improved process for pretreating a naphtha comprises contacting the naphtha feedstream with a crystalline zeolite catalyst containing 3 1 noble metal and 2 1 alkali metal, prior to reforming, thereby increasing the yields of Cp4 distillates and CB5 gasoline. The noble metal includes Pt. Pd. Ir, Rh and Flu; the alkali metal includes Li, Na, K, Rb and Cs.

Waste gas containing NO. is contacted with a catalyst comprising H-form mordenite or clinotilolite loaded with B 1 of Cu, Cr, Mn, Fe, Ni, Co, Rh, Pd. Pt, V, and MO, in the presence of an organic compound, e.g., propane, to remove N oxides from the waste gas. The method does not need NH3 and is effective under Oz-rich conditions.

A paraffinic feedstream is aromatized in an FCC external catalyst cooler by contacting the paraffinic feedstream with hot regenerated cracking and additive catalysts. Hot regenerated large-pore zeolite cracking catalyst from an FCC regenerator dehydrogenates the paraffins and a medium-pore acid zeolite additive catalyst aromatizes the resulting olefins.

Secondan/ amines are prepared by treatment of primary amines with alcohols or aldehydes in the presence of catalysts composed of Cu, Pt-group metals, and alkali metals or alkaline earth metals supported on a crystalline synthetic zeolite.
Catalysts for removing NO,, CO, and hydrocarbons from automobile exhaust gases comprise CU2+-exchanged zeolite loaded on a porous monolithic support. The pore diameter of zeolite in the upper stream side is preferably larger than that in the down stream side. Thus, a cylindrical cordierite monolithic support was loaded with Cu*+exchanged ZSM-5 zeolite in the upper stream, and with Cu*+exchanged ferrierite-type zeolite down stream to form a durable catalyst with increased reduction efficiency during high temperature operation.

A one-stage catalytic process for producing high-octane gasoline from a highly aromatic hydrogen feedstock comprises hydrocracking the feedstock with a Ni-W/MCM 22 zeolite catalyst. Fractionation of the hydrocracker effluent provides a high-octane gasoline fraction.
Gasoline with high octane number is prepared from CM fractions using a catalyst of acid-treatment mordenite post-treated with OS, e.g., air and steam, to optimize the Si0z:Alz03 ratio. The treated mordenite is then mixed with A1203 and a Group VIII metal, especially Pd, Pt, or Ni, calcined, and reduced in a H2 current.
