Abstract: Hydraulic binder-contg. nickel catalyst is produced by pptg. Ni5MgAl2(OH)16.CO3.4H2O or Ni6Al2(OH)16.CO3.4H2O from aq. soln. onto suspended carrier particles, separating the particles carrying the above salt, drying, calcining, mixing with a calcium aluminate cement and water, moulding, allowing to set, and reducing the salt to produce nickel catalyst. The calcium aluminate cement is used in an amt. of 5-40 wt % w.r.t. the calcined mixt. The catalyst is used for methanation of gases contg. carbon oxides (usually 10-32 wt % CO) and hydrogen at 250 degrees C. Within this temp. range, the catalyst has good mechanical strength and activity.

Abstract: Title cpds. have the molar compsn. XM2/nO.Al2O3.YSiO2.ZBeO.WH2O in which M is an exchangeable cation of valency 'n', pref. Na X is 0.8 to 6.2, is 3 to 15, Z is 0.01 to 5, and W is 0 to 6. Starting matls. are beryllium contg. minerals, silicic acid gels, or sols. the acid itself, sodium silicate, Al2O3 or aluminium hydroxide. The solns. are initially prepd. in the cold, then brought to 70-150 degrees C with stirring and left at this temp. for 10-100 hrs. The prds. are used for the same purposes as naturally occurring zeolites.
