Process for the catalytic hydrogenation of liquid fatty acid triglycerides for simultaneous production of fatty alcohols and c3-diols

摘要: Using a process for catalytic hydrogenation of liquid fatty acid triglycerides simultaneous production alcohols and C3-diols in the presence gaseous hydrogen catalysts at pressures from 50 to 300 bar temperatures 160 250 DEG , yield least 99% theory 1,2-propanediol 80% maximum paraffin content most 0.5% is achieved by carrying out reaction shell-and-tube reactor held under isothermal conditions means cooling or heating fluid, phase being passed over catalyst packings individual tubes as parallel current addition without remixing, selecting volume loading between 0.2 2.5 l feedstock per hour surface each tube 1.5 25 m cross-section adjusting parameters temperature pressure actual activity correspondingly. …
