Abstract: | A biodiesel production process using magnetically stabilized fluidized bed reactor (MSFBR) has been developed based on the
refined cottonseed oil. The reactant flow rate and magnetic field intensity effects on the nanometer magnetic catalyst behavior
in the column were investigated. Orthogonal experiments (L4(2)3) were applied to optimize the best transesterification reaction conditions. Reaction temperature, methanol to oil molar ratio,
and reactant flow rate were the main factors to influence transesterification conversion efficiency. These three factors chosen
for the present investigation were based on the results of single-factor tests. The optimum transesterification reaction conditions
of cottonseed oil were determined in MSFBR as follows: methanol to oil molar ratio 8:1, 40 cm3 min−1 reactant flow rate, 225 Oe magnetic field intensity and reaction temperature of 65 °C, the conversion efficiency reached
97% in 100 min. The cold filter plugging point and kinematic viscosity of cottonseed oil biodiesel were higher than that described
by Chinese specifications of biodiesel because of the special fatty acid profiles of cottonseed oil. The activity stability
of the nanometer magnetic solid catalyst in MSFBR was much better than that in the autoclave stirred reactor (ASR). |
