Claims20
A pyrolysis, thermal cracking, or steam cracking reactor for cracking hydrocarbons wherein the reactor has an inner wall;
- characterized in that the inner wall comprises a plurality of concave dimples embedded in a surface of said inner wall, characterized by an area coverage (AC) defined as
- AC (%)=total area of the inner wall covered by dimples/total area of the inner wall*100;
- wherein the AC is at least 20% and at most 90%;
- and,
- wherein each concave dimple of the plurality of concave dimples is characterized by a dimple diameter d, wherein d is at least 0.1 cm and at most 5.0 cm.
