REACTOR FROM PLATED STAINLESS STEEL FOR THE CONTINUOUS HETEROGENEOUSLY CATALYZED PARTIAL DEHYDRATION OF AT LEAST ONE HYDROCARBON TO BE DEHYDRATED, AND CORRESPONDING METHOD

摘要

THE INVENTION RELATES TO A METHOD FOR THE CONTINUOUS HETEROGENEOUSLY CATALYZED PARTIAL DEHYDRATION OF AT LEAST ONE HYDROCARBON TO BE DEHYDRATED IN A REACTOR, SAID REACTOR BEING PRODUCED FROM A COMPOSITE MATERIAL. ON ITS SIDE CONTACTING THE REACTION CHAMBER, THE REACTOR CONSISTS OF A STEEL B HAVING A SPECIFIC ELEMENTAL COMPOSITION, WHICH, ON THE SIDE FACING AWAY FROM THE REACTION CHAMBER, IS PLATED EITHER DIRECTLY OR VIA AN INTERMEDIATE COPPER, OR NICKEL OR COPPER AND NICKEL LAYER ONTO A STEEL A HAVING A SPECIFIC ELEMENTAL COMPOSITION. THE INVENTION ALSO RELATES TO METHODS FOR PARTIAL OXIDATIONS OF THE DEHYDRATED HYDROCARBON AND TO THE REACTOR AS SUCH. STEEL A IS A HIGH-GRADE CHROMIUM-NICKEL STEEL HAVING A LOW Si CONTENT (1% Si), E. G. OF THE TYPE DIN 1.4910 OR 1.4958. STEEL B IS A HIGH-GRADE CHROMIUM-NICKEL STEEL HAVING A HIGHER Si CONTENT (1-4%), E. G. OF THE TYPE DIN 1.4841. THE COMPOSITE MATERIAL, DUE TO SIMILAR THERMAL EXPANSION COEFFICIENTS OF THE INDIVIDUAL STEEL LAYERS, HAS A HIGH RESISTANCE TO THERMAL CYCLING, A HIGH RESISTANCE TO LONG-TERM EMBRITTLEMENT, CARBURIZATION, METAL DUSTING, AND A REDUCED UNDESIRED CATALYTIC EFFECT.
