OIL OF COTTON SEED - Study on transesterification of cottonseed oil to biodiesel catalyzed by solid base

from Baidu library

Author:

Chen he , Wang Jinfu

Summary:

Biodiesel (fatty acid methyl ester) can be prepared from cottonseed oil and methanol through transesterification under the action of alkali catalyst. In this experiment, the corresponding solid alkali catalysts MgO,CaO and MgO-Al2O3 were obtained by calcining magnesium hydroxide, calcium carbonate and magnesium-aluminum hydrotalcite at high temperature, and the activity of the catalysts was evaluated. The experimental results show that CaO and MgO-Al2O3 have high transesterification activity: under the conditions of 230 ℃, alcohol-oil molar ratio of 12:1 and cottonseed oil dosage of 2%(wt), the yield of methyl ester reaches more than 90% after 3 hours of reaction. CO2-TPD experimental results show that CaO and MgO-Al2O3 have strong and more basic sites, while the activity of the catalyst is directly related to the alkali strength and the number of basic sites.

Summary:

Taking cottonseed oil methyl ester, ethyl ester biodiesel and its blend oil formed with petrochemical diesel as research objects, the biodegradation characteristics of biodiesel and its blend oil were investigated by using the improved Sturm test method. The results show that the biodegradation rates of cottonseed ethyl biodiesel and methyl ester biodiesel are 99.7% and 99.1% respectively after 28 days of biodegradation in aerobic water environment. For methyl ester biodiesel, the 28d biodegradation rates of blend oil with volume fraction of 50% and 20% are 93.8% and 80.8% respectively, while the 28d biodegradation rates of blend oil with volume fraction of 50% and 20% are 95.7% and 81.9% respectively, however, under the same conditions, the biodegradation rate of 0# diesel oil is only 49.9%. The larger the volume ratio of biodiesel in the blend oil, the faster the biodegradation rate of the blend oil. Biodiesel can promote the biodegradation of petrochemical diesel oil. This paper has certain significance for understanding the digestion law of cottonseed oil biodiesel in the environment and controlling environmental pollution.
