Thermal cracking process using tubes, pipes, and coils made of novel stainless steel matrix |
| 摘要 |
A thermal cracking process using tubes, pipes, and coils made of. An outermost surface covering not less than 55% of stainless steel, said surface having a thickness from 0.1 to 15 microns and being a spinel of the formula Mn<SUB>x</SUB>Cr<SUB>3-x</SUB>O<SUB>4 </SUB>wherein x is from 0.5 to 2 is not prone to coking and is suitable for hydrocarbyl reactions such as furnace tubes for cracking.
