![عکس صفحه اول مقاله: Production of butyl-biodiesel using lipase physically-adsorbed onto electrospun polyacrylonitrile fibers Production of butyl-biodiesel using lipase physically-adsorbed onto electrospun polyacrylonitrile fibers](/preview/png/682820.png)
Butyl-biodiesel production using electrospun polyacrylonitrile fibers with Pseudomonas cepacia lipase immobilized through physical adsorption was studied. About 80% conversion to butyl-biodiesel was achieved after 24 h by suspending the catalyst at 2.4 mg/mL in a mixture of rapeseed oil and n-butanol at a molar ratio of 1:3, containing water at 8000 ppm at 40 °C. A further 24 h of operation resulted in 94% conversion. The initial reaction rate detected for this process was 65-fold faster than those detected for Novozym 435 on a total catalyst mass basis. The immobilized lipase continued to work as a catalyst for 27 d, within a 15% reduction in conversion yield at the outlet of the reactor compared with the average value detected during the first 3 d of operation in a continuous butyl-biodiesel production system.
