Abstract:
1. Isothermal reactor ( 1 ) comprising a substantially cylindrical shell ( 2 ), at least one catalytic bed ( 10 ) supported in said shell ( 2 ) and at least one heat exchange unit ( 13 ) supported in said bed ( 10 ), said heat exchange unit ( 13 ) comprising a plurality of exchangers ( 14 ) substantially box shaped, of essentially elongated rectangular and flattened structure, said exchangers ( 14 ) having opposite long sides ( 14 a ) parallel to the axis of the cylindrical shell and opposite short sides ( 14 b , 14 c ) extended perpendicularly with respect to said axis and comprising furthermore an inner chamber ( 18 ) through which a heat exchange operating fluid is intended to flow, characterized in that at least one exchanger ( 14 ) of said at least one heat exchange unit ( 13 ) is internally equipped with a plurality of separation baffles ( 19 ) extended from a short side ( 14 b or 14 c ) of the exchanger to the opposite short side ( 14 c or 14 b ) and in a predetermined spaced relationship with respect to the latter, defining in said inner chamber ( 18 ) a substantially zigzag fluid path having alternating ascending and descending portions.
