摘要： The present invention relates to processes for isomerizing normal paraffin hydrocarbons to produce products containing non-normal hydrocarbons using a zeolite beta catalyst that has been activated in order to enhance its catalytic properties. In accordance with the present invention, the zeolite beta catalyst is activated at a temperature effective to substantially reduce the concentration of strong acid species, i.e., hydronium cations, without substantially reducing the concentration of weak acid species, i.e., hydroxoaluminum cations, both of said strong acid species and weak acid species being initially present on the catalyst prior to activation. In addition, the isomerization step is preferably conducted at a temperature at least 300.degree. C. lower than the activation temperature. Additional treatment steps that are preferably performed prior to the activation step described above include a calcining step wherein a synthesized zeolite beta catalyst containing a templating agent is calcined at a temperature in the range of from about 200.degree. to 1000.degree. C. in order to remove a substantial portion of the catalyst templating agent and an ion-exchanging step wherein the calcined catalyst is ion-exchanged with a salt solution containing at least one hydrogen forming cation selected from NH.sub.4.sup.+ and quaternary ammonium.

摘要： This invention relates to processes for preparing ceramic articles. One process involves taking a potassium exchanged zeolite, the zeolite characterized in that it has a SiO.sub.2 /Al.sub.2 O.sub.3 ratio of 3.5 to about 7.5, and calcining it at a temperature of about 900.degree. to about 1100.degree. C. for a time sufficient to collapse the zeolite framework and provide an amorphous powder. Next, the amorphous powder is formed into a shaped article and the article is sintered at a temperature of about 1150.degree. to about 1400.degree. C. for a time of about 0.5 to about 12 hours to give a ceramic article whose principal crystalline phase is tetragonal leucite, is substantially crack free, and has less than 5% porosity. When the zeolite is exchanged with cesium, one obtains a ceramic article whose principal crystalline phase is pollucite, when a rubidium exchanged zeolite is used one obtains a ceramic article whose principal crystalline phase is rubidium leucite, and when a potassium/cesium exchanged zeolite is used one obtains a ceramic article having as its principal crystalline phase a leucite/pollucite solid solution. The addition of pollucite to the leucite article provides a ceramic article whose thermal expansion coefficient can be varied from about 2.times.10.sup.-6 to about 27.times.10.sup.-60 C.sup.-1 as measured over the range 50.degree.-700.degree. C. This invention also relates to this leucite/pollucite ceramic article.
