Abstract
AbstractFatty acids (FAs) are a very important group of raw materials for chemical industry, and the technology of separating or purifying the FAs from the reaction product mixture has always been the hotspot of research. Membrane processes for separation of FAs are being increasingly reported. Compared with conventional FAs separation methods, membrane separation has the advantages of low energy consumption, system compactness, high separation efficiency, easy scale-up, high available surface area per unit volume and low working temperatures, thereby attracting considerable attention of many researchers. In this regards, this paper critically reviewed the developments of methods for FAs separation and purification, and the future prospects of coupling membrane technology with hydrolysis for enhanced production of FAs.

Abstract
Abstract
The integration process of polyethersulphone (PES) ultrafiltration with catalytic hydrolysis of lard was optimized by response surface methodology (RSM). The influences of molar ratio of water to lard, reaction time and transmembrane pressure on the fatty acids (FAs) yield were investigated. Results showed that the maximum FAs yield of 99.52 % was obtained under the optimized conditions of molar ratio of water to lard of 6.0:1.0, reaction time of 10.0 h and transmembrane pressure of 100.0 kPa. Moreover, the membrane cleaning efficiency was studied after four cleanings. Furthermore, the kinetic model of membrane separation process was investigated and the activation energy and pre-exponential factor were determined.
