    • This invention relates to a method of conducting a chemical reaction in the presence of a heterogeneous catalyst, in which a feedstock is passed through a catalytic reactor, said reactor comprising a solid reactor bed with a catalytically active material present thereon, and at least one heat supplying and/or discharging reactor wall, and in which the catalyst bed consists of elementary particles of material sintered together and to one side of the wall, there being no sintered material present on the other side of the reactor wall, and in which the maximum distance in meters (x max ) of any point of the reactor bed to a nearest heat supplying and/or discharging wall is determined by the following formula: in which
      λ is the effective coefficient of heat conductivity in W/mK of the sintered material and has a value between 2 and 250;
      αi is the coefficient of heat transfer in W/m²/K on the reactor side of the heat supplying and/or discharging reactor wall and equals ε α, where ε has a value of between 1.0 and 10 and indicates the increase in heat transfer by sintering the material, and α is the coefficient of heat transfer from the reactor bed in the non-sintered state;
      ΔT max , measured across a radial cross-section through the reactor bed, is the absolute value of the difference in temperature between any point in this cross-section and the nearest heat supplying and/or discharging reactor wall, the maximum permissible value of which ranges between 1 and 1000 K;
      a is a form factor determined only by the geometrical shape of the reactor and has a value between 0.25 and 0.5, respectively;
      a′ is a form factor representing the ratio between the area of the reactor cross-section and the heat exchanging circumference of said reactor cross-section multiplied by x max and has a value between 0.5 and 1; and
      q is the maximum reaction heat, in W/m³, generated in the reactor bed and which must be supplied and/or discharged through the wall in radial direction.
