FIELD: heterogeneous catalysis, catalytic micro-reactors, possibly manufacture of carriers of stainless steel with developed porous structure of surface designed for securing catalyst. ^ SUBSTANCE: method comprises steps of anode electrochemical etching of stainless steel in solution of iron chloride with concentration no more than 200g/l at electric current density 21 - 50 A/dm2. Method according to second variant of invention comprises steps of anode electrochemical etching of stainless steel in solution of sodium chloride with concentration no more than 200g/l at electric current density 11 - 25 A/dm2 while adding sulfuric acid to sodium chloride solution. Metallic carrier of stainless steel for catalyst includes on its surfaces drop-shaped etched depressions. Upper edge of depression has round shape with diameter 0.05 - 0.4 mm; mean volume of depressions is 4 x 10-4 cm3; surface density of depressions is in range 250 - 350 depressions per cm2. ^ EFFECT: improved surface structure of catalyst carrier. ^ 6 cl, 4 ex, 1 dwg |
