A new alumina-supported, not pyrophoric Raney-type Ni-catalyst
Starting with a 50-50 wt.% Al-Ni alloy powder a new process was developed by which an active alumina supported, not pyrophoric Raney-type Ni catalyst is produced. It consists of very finely dispersed nickel of 25-30 wt.% (specific weight of about 1.2). The Ni is not ferromagnetic. The catalyst is applied in all liquid Phase hydrogenations where standard Raney-Ni is used, with the same or higher specific activity. The structure of the catalyst is described using XRD, SAXS, TEM SEM/EDX, and N-2-sorption. The catalytic activity measurements were performed in liquid phase hydrogenations at room temperature and atmospheric pressure.
