Abstract: A novel aqueous solution for the one step impregnation of catalytic supports, catalysts prepared from such solution, and the preparation and the use of catalysts prepared thereby. The catalysts prepared are used in the hydrotreatment of petroleum fractions and particularly in hydrodesulfurization and/or denitrogenization. The solution is a combination of at least one compound of a metal from group IVa (e.g. Zr), at least one compound of a metal from group VIa (e.g. Mo or W), at least one compound of a metal from group VIII (e.g. Co or Ni), and at least one water soluble amine (e.g. ethylenediamine or MEA).

Abstract: A process for the preparation of granules containing at least one active principle with a melting point above 70.degree. C. selected from the group consisting of herbicides, fungicides and insecticides comprising dissolving the active principle in an aromatic solvent or pyrrolidone, absorbing the resulting solution on a support, optionally adding water thereto and drying the resulting product to form the granules and the granules produced thereby which have a superior biological activity than a granule dispersible in water with good stability.

Abstract: A fluidized-bed process for catalytic cracking of a hydrocarbon feedstock where the hydrocarbon feedstock, particularly a feedstock with a high content of basic nitrogen compounds, and a catalyst circulate in the tubular zone co-currently from the top to the bottom, where the catalyst, which is under equilibrium conditions at 150.degree. C., and a pressure of 5 mbar, adsorbs less than 250 micromols, and preferably less than 50 micromols, of pyridine/g, and whose pyridine retention, after heating at 350.degree. C. under vacuum, does not exceed 20%, and preferably not 10%, of the amount adsorbed at 150.degree. C.

Abstract: The invention concerns a fluidized bed cracking process of a hydrocarbon charge, carried out in an extended, appreciably tubular and vertical reaction zone (1), the catalyst being introduced at the lower end of this extended zone by a piper (2), and the charge being introduced by at least one pipe (3) opening into the reaction zone at a level higher than the level at which the catalyst is admitted.The invention wherein, for example, part of the gasoline or part (3a) to an intermediate point between the catalyst and charge entry points, and wherein a specially adapted catalyst is used for this operating procedure. The invention also concerns the catalyst used in this way, a zeolite-based catalyst of the erionite family.

Abstract: The invention relates to the preparation of synthetic zeolites selected from the group formed by chabazite, merlinoite, edingtonite, ZSM 5 and ZSM 11.In accordance with the invention, a zeolite selected from the group formed by mordenite, ferrierite, clinoptilolite and the type X and type Y zeolites is subjected to a treatment with at least one base.The invention further relates to zeolites obtained by said process.

Abstract: The invention relates to the preparation of the zeolite ZK-5 from a starting zeolite selected from the group consisting of the zeolites P (Cl), P' (Cl), Q (Br) and Q' (Br).In accordance with the invention, the barium ions contained in the starting zeolite are extracted therefrom by means of a barium-binding agent selected from the group consisting of precipitating agents which form with the barium ions a compound that precipitates, and of complexing agents which form with the barium ions a barium complex.The zeolite ZK-5 obtained may be used in the separation or cracking of hydrocarbons.
