Modified kinetic modelling of isoamyl acetate production

Modified kinetic modelling of isoamyl acetate production / Loh Woei Fang
Isoamil Asetat mempunyai pasaran yang besar. Model kinetik diperlukan untuk memahami hubungan antara parameter operasi untuk mencapai kadar pengeluaran dan hasilnya dengan tinggi, Pemodelan kinetik dikaji untuk menganggarkan profil kepekatan dari semasa ke semasa. Model kinetik tidak dapat menggambarkan profil disebabkan oleh perubahan dalam pH, andaian tidak sah dan perisian had. Profil kepekatan boleh diramal dengan baik apabila nisbah Ac/Al adalah rendah dan ia ralat kuasa dua adalah rendah. Oleh itu, model kinetik adalah hanya sah untuk keadaan / Al nisbah Ac rendah dan pada suhu optimum 30 - 40 ℃.Keadaan optimum nisbah Ac/Al adalah 0,217 untuk mencapai hasilan 90%. masa optimum diambil adalah untuk 4 wt% , 8wt% dan 12% berat enzim adalah 30.6 min, 23.3 min dan 19.3 min. _______________________________________________________________________________________________________ Isoamyl acetate has high market demand. To achieve high production rate and yield, kinetic model is required in order to the understand relationship between operating parameters. The kinetic modelling is studied to estimate the concentration profile from time to time. The kinetic model developed in this work was not perfect due to the variation in pH, invalid assumption and software limitation. Concentration profile can be predicted well when Ac/Al ratio is low and it squared error is low. Therefore, the kinetic model was only valid for condition of low Ac/Al ratio and at optimum temperature 30 – 40 ℃. The optimum condition of Ac/Al ratio was 0.217 to achieve 90% yield. Optimum time taken for 4 wt%, 8wt% and 12 wt% enzyme were 30.6 min, 23.3 min and 19.3 min respectively.
