Reactor suitable for the chemical reactions involving of the fluids in contact with a bed of solid materials

摘要

P the invention relates to a reactor for chemical reactions involving of the gas or fluid in contact with a bed of solid materials, with a substantially radial circulation of the gas or fluid). / p & & p & this reactor is characterized by the fact that the cylindrical part of the bed of solid matter is surmounted by a reactive zone is substantially hemispherical permeable to gas or fluid). / p & & p & application to the catalytic dehydrogenation of the hydrocarbons. / p
