PROCEDURE TO REGULATE THE AMOUNT OF USED CATALYST THAT RETURNS TO A HYDRATION DEVICE TO MANUFACTURE FATTY ALCOHOLS FROM FATTY ACIDS AND / OR DERIVATIVES OF FATTY ACIDS.

摘要

A DISPERSION CONTAINING THE FATTY ACIDS AND / OR THEIR DERIVATIVES, HYDROGEN, AN UNUSED CATALYST, AND A USED CATALYST, AND A TEMPERATURE BETWEEN 100 AND 400 CONTAINING ALCOHOL PRODUCTS, ARE BROUGHT TO THE HYDROGENATION FACILITY USED. THE PRODUCT FLOW IS PARTIALLY RECIRCULATED, EXTRACTING FROM THIS RECIRCULATION A FIRST PARTIAL FLOW WITH ADJUSTABLE QUANTITIES AND DIRECTING IT TO A SEPARATING DEVICE. FROM THIS COMES A PRODUCT RICH IN FATTY ALCOHOL, AND SEPARATED FROM IT A DISPERSION CONTAINING A USED CATALYST, WHICH IS RETURNED TO THE HYDROGENATION FACILITY. A SECOND PARTIAL FLOW WITH ADJUSTABLE AMOUNTS IS REMOVED FROM THE RECIRCULATION OF THE PRODUCT FLOW AND THERE IS A USED CATALYST, WHICH IS DEFINITELY REMOVED FROM THE PROCESS. TO INCREASE THE CATALYST AMOUNTS REDIRECTED TOWARD THE HYDROGENATION INSTALLATION, THE AMOUNT OF THE SECOND PARTIAL FLOW IS REDUCED.
