Hydrogen and carbon monoxide are produced from a low molecular weight hydrocarbon by contact thereof, at high temperature in the presence of oxygen or, steam and oxygen, with a fluidized bed comprising said particulate solids. In one of its forms, barium hexaluminate is employed as a heat transfer solid, in concentrations ranging generally from about 10 wt% to about 99.9 wt%, in admixture with a particulate catalyst containing a metal, or metals, component catalytic for the production of hydrogen and carbon …

Why it's free to use

  • Filed April 26, 1994 and granted July 18, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 26, 2014.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 26, 2016.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
