摘要

The hydrogenation of fatty acid methyl ester in fatty alcohols using fixed bed reactor, comprises producing fatty acid methyl ester using auxiliary reactors, regenerating a catalyst charge of auxiliary reactor arranged in pre- and post- reactors, repeating the fatty acid methyl ester production, treating a pure and less pure of fatty acid methyl ester product at the same time, and introducing a pure and a less pure fatty acid methyl ester product in principal reactors with/without the pre-reactor. The principal reactor contains large and small quantity of catalyst. The hydrogenation of fatty acid methyl ester in fatty alcohols using fixed bed reactor, comprises producing fatty acid methyl ester using auxiliary reactors, regenerating a catalyst charge of auxiliary reactor arranged in pre- and post- reactors, repeating the fatty acid methyl ester production, treating a pure and less pure of fatty acid methyl ester product at the same time, and introducing a pure and a less pure fatty acid methyl ester product in principal reactors with/without the pre-reactor. The principal reactor contains large and small quantity of catalyst. The auxiliary reactor is arranged in an upstream and downstream of the principle reactor. A maximum liquid flow is used in the fatty acid methyl ester production and in the auxiliary reactor with the catalyst charge in post reactor. A minimum liquid flow is used in the catalyst charge regeneration in pre- and post- reactors. Long chain of 12-14C fatty acid methyl ester is used as the pure product, and long chain of 12-22C, 12-18C, 16-22C or 16-18C fatty acid methyl ester is used as the less pure product. The less pure product is treated in the pre-reactor and pure product is treated in the post-reactor. The auxiliary reactors are designed in a form of tank and principal reactors are designed as a tubular beam in the form of tank.
