  • a process is known, from my application Ser. No. 56,885, filed July 2], i970, for flameless combustion of gases in porous sinter blocks, wherein a mixture of hydrocarbons and oxygen or a hydrocarbon and air mixture is burned in a highly porous sinter block, provided with passage openings.
  • said sinter block containing nickel or platinum.
  • sinter blocks containing nickel may reach temperatures of 900 to l,400C
  • sinter blocks containing platinum may reach temperatures up to l.650C.
  • the hydrocarbons employed may easily be evaporated by preheating.
  • Particularly suitable are hydrocarbons of formula C H to C,,H that is those hydrocarbons which are liquid at room temperature.
  • the original materials are installed when nickel catalysts are used, preferably in a stoichiometric ratio, for example. according to the equation:
  • the sinter blocks used for flameless combustion comprise a highly porous material which is essentially open-pored, for example a sintered magnesium aluminum oxide. They comprise additional, preferably parallel positioned passage openings.
  • the passage openings may have a pore radius of approximately 0.5 mm, whereby about 40 passageopenings are provided per 1 cm of sinter block area.
  • the entire pore volume should be at least 50 volume-percent, but is preferably about 65 volume-percent.
  • the additional passage openings first ofall. prevent clogging of the sinter block by contamination and, secondly, facilitate and increase the throughput of the gas mixture considerably.
  • the installation of the nickel or platinum catalyst is carried out in a known fashion through impregnation of the sinter block with a nickel salt solution, or a platinum salt solution, or with a platinum acid solution.
  • Suitable nickel salts are, for example, nickel acetate, nickel carbonate, nickel formate, etc.

  • nickel in the sinter block may amount to l mg/cm to 200 mg/cm, but may also be higher. An increase in sinter block load capacity could no longer be observed with nickel quantities of 500 mg/cm, 800 mg/cm and above. Particularly suitable were found to be nickel quantities of 10 to mg/cm.
  • the platinum content is about 0.] to mg/cm but preferably 5 to 10 mg/cm. It is essential for the selection of the catalyst salt that the salt be easy to dissociate thermally. After drying in air or, if necessary, with heat, the sinter block may immediately be installed as a radiation surface into an appropriate heating chamber.
  • a mixture of benzenevapor and air in a stoichiometric ratio is combusted in a sinter block wherein 50 mg/cm nickel are uniformly distributed, one obtains, depending on the radiation ratio and gas mixture, a surface temperature of about l,lOOC to 1,450C and when combustion takes place in a sinter block containing 5 to 10 mg/cm platinum, a surface temperature of up to l,600C is obtained according to the higher reaction.
