Catalytic methods for the production of saturated hydrocarbons with 2 to 5 carbon atoms per molecule by conversion of small hydrocarbon halides and/or hydrogenation of carbonaceous material are disclosed that result in high yield of saturated C2 to C5 hydrocarbons at reduced corrosion of the reactors and in good lifetime of the catalyst. The methods are performed in the presence of a Lewis acid comprising catalyst and in the absence of oxygen or oxygen containing compounds, whereby an upper limit of at most 50 parts per million mass of oxygen or oxygen containing compounds can be tolerated.

Production of saturated C2 to C5 hydrocarbons

The present relates to the field of dental and bone surgery. In particular, the invention relates to fibrous pharmaceutical compositions; fibrous webs, yarns and woven fabrics of such pharmaceutical compositions; to implant material essentially consisting of fibrous pharmaceutical compositions; to the manufacturing and use of such fibers/webs/implant materials.

Implant material

Described is a method for the production of pure or mixed metal oxides, wherein at least one metal precursor that is a metal carboxylate with a mean carbon value per carboxylate group of at least 3, e.g. the 2-ethyl hexanoic acid salt, is formed into droplets and e.g. flame oxidized. The method is performed at viscosities prior to droplet formation of usually less than 40 mPa s, obtained by heating and/or addition of one or more low viscosity solvents with adequately high enthalpy.
