TH51854A - Hydrogenation of benzene to cyclohexane - Google Patents

Abstract

DC60 (29/09/43) Process for the production of cyclohexane by hydrogenation of benzene. Was provided where the reaction machine was operated At pressure where the reaction mixture boils under partial pressure of hydrogen in the range of approximately 0.1 psia to less than 200 psia at upper pressure 0 to 350 psig. Prepared as a refining structure that catalyzes the reaction to Simultaneous reactions With benzene distillation is entered at Bed position above And hydrogen is fed below the bed, the entire upper substance may return as reflux to cool the catalyst bed, the process for the production of cyclohexane by hydrogenation. Of benzene Was provided where the reaction machine was operated At pressure where the reaction mixture boils under partial pressure of hydrogen in the range of approximately 0.1 psia to less than 200 psia at upper pressure 0 to 350 psig. Prepare as A refining structure that catalyzes the reaction to provide Simultaneous reactions With benzene distillation is entered at Bed position above And hydrogen is fed below the bed, all of the upper substances may return as reflux to cool the inside of the talist's bed.
