    摘要： The invention relates to a method for purification of phenol and specifically to a method for purification of phenol produced within the process of joint phenol and acetone production by cumene method.The aim of the invention is to develop a catalyst which has high activity for phenol purification from organic mico-impurities with regeneration of the catalyst and which has high mechanical strength and stability with long catalyst life.This result is obtained by phenol purification using a heterogeneous zeolite catalyst. The acidity of the catalyst measured by butane cracking (K.sub.A) is more than 10.It is preferable to use zeolites which are designated according to the classification of the International Zeolite Association by indices FAU (zeolites X, Y), MFI (for example, ZSM-5), MOR (mordenite), MAZ (omega), BEA (beta), FER (ferrierite) and others. These zeolites can be used with binders (aluminum oxide, silica gel, aluminosilicates or aluminophosphates) and without them. It is preferable to use zeolite of the Y type with an aluminosilicate binder and a the value of K.sub.A =50-80 cm.sup.3 /min*g and Si/Al ratio more than 3. The concentration of sodium, potassium and other alkali agents on the basis of their oxides does not exceed 2 wt %, preferably not more than 0.3 wt %. It is preferable to use zeolites with medium and large pores. Size of zeolites pores should be within the range 4 .ANG. in diameter and more. The most preferable zeolites are with large pores (>6 .ANG. in diameter) such as Y and mordenite.

    摘要： The invention refers to a process for the obtainment of a catalyst useful in the isomerization of light paraffins, fundamentally based on acid treatment of a synthetic mordenite at temperatures between 40.degree. and 100.degree. C. followed by treatment with steam-air at temperatures between 300.degree. and 600.degree. C. which make it possible to optimize the SiO.sub.2 /Al.sub.2 O.sub.3 framework ratio and the amount of extraframework aluminum of the zeolite. The mordenite thus obtained is mixed with an inorganic refractory oxide such as Al.sub.2 O.sub.3 and a metal of group VIII, basically Pt, is added in an amount between 0.1 and 0.5% by weight referred to the final catalyst.The catalyst has been tested in the isomerization of light refinery fractions (C.sub.5 and C.sub.6) and has a high activity and selectivity of branched isomers with a low production of gases and a high octane number for the light gasoline obtained.

    摘要： The invention describes a highly efficient catalytic pollution control process for removing N.sub.2 O from gaseous mixtures. The catalytic process, which is substantially unaffected by the presence of oxygen, comprises contacting an N.sub.2 O-containing gaseous mixture with a catalyst comprising a crystalline zeolite which, at least in part, is composed of five membered rings having a structure type selected from the group consisting of BETA, MOR, MFI, MEL and FER wherein the crystalline zeolite has been at least partially ion-exchanged with a metal selected from the group consisting of copper, cobalt, rhodium, iridium, ruthenium and palladium under conditions sufficient to convert the N.sub.2 O into gaseous nitrogen and gaseous oxygen.

    摘要： A moderate pressure hydrocracking process is disclosed in which substantially dealkylated heavy distillate feedstocks are processed directly to high octane gasoline over a catalyst, preferably comprising a crystalline silicate zeolite hydrocracking component having a Constraint Index less than 2. The bottoms fraction produced from the contacting may be passed to an FCC unit for further processing. In another embodiment, the substantially dealkylated heavy distillate feedstock may be fractionated into a lighter boiling stream and a heavier boiling stream for better ease of processing.
