    Abstract: Light olefin fractions or their mixts. are oligomerised in the presence of a BF3 catalyst on an alumina support of low specific surface and low pore volume. The specific surface is pref. 20-120, esp. 40-100 m2/g and the pore volume is pref. 0.10-0.80, esp. 0.20-0.50 cc/g. The supported catalyst is also claimed. Pref. the specific surface and pore volume of the alumina support are adjusted by controlling the duration and temp. of calcination of a coarse support. Oligomerisation is at 30-130 deg.C and 10-50 bars. Pref. olefins comprise mainly propylene and/or butenes. The catalyst is cheap and easy to charge and gives low boiling oligomers with improved selectivity while limiting formation of high boiling polymsn. residues.

    Abstract: In a combined process for the storage and production of hydrogen from a hydrogen reserve containing magnesium in the free or combined state, said process consisting of storing the hydrogen in the supply, decomposing the supply to produce hydrogen, and reconstituting the supply of hydrogenation; the use of a dope comprising two elements in the free or combined state selected from the group consisting of cerium, nickel, titanium and molybdenum. Said process may be applied to hydrogen reserves used to fuel internal-combustion engines and for similar applications.
