Method of the removal of the templating agent from synthetic zeolites

Process for the preparation of amides via the catalytic rearrangement of oximes which comprises putting an oxime in vapor phase in contact with a catalyst selected from a mesoporous silica-alumina having a molar ratio SiO/Al.sub.2 O.sub.2 of between 20 and 1000, an average pore diameter of between 20 and 100 .ANG. and an X-ray diffraction pattern (XRD) from powders which, after calcination, has the deepest reflection at d-spacing of more than 18 .ANG. (2.theta.&lt;4.9.degree., CuK.alpha. radiation).

Process for the preparation of amides from oximes

Process for the preparation of caprolactam by the catalytic rearrangement of cyclohexanone oxime in which a vapour phase oxime is contacting a catalyst selected from an essentially amorphous, micro-mesoporous silica-alumina having a molar ratio SiO.sub.2 /Al.sub.2 O.sub.3 of 30 to 5000, a surface area of at least 500 m.sup.2 /g and a total pore volume of 0.3 to 1.3 ml/g.

Methane is converted into higher hydrocarbon products, and especially into ethane and ethylene, by oxidative coupling, by bringing a gaseous mixture containing methane and oxygen into contact at high temperature for a short contact time with a solid catalyst formed from lithium oxide, an alkaline earth metal oxide (preferably of magnesium) and a lanthanide oxide (preferably of neodymium or lanthanum), in which the lithium content is less than 0.20% by weight and the atomic ratio of the alkaline earth metal to the lanthanide varies from 0.8/1 to 8/1, said catalyst being obtained by:
