Evidence Details
Release-kinetics evidence: source values include 0.5619%, 2.7562%, R2 = 0.9984, R2 = 0.9675.
Equipment-detail evidence: magnetic stirring.
RSM combined with BBD shows the optimal conditions as catalyst loading of 5.85 g, mass ratio of ethanol to acidified oil of 0.35 (20.0 g acidified oil), microwave power of 328 W and reaction time of 98.0 min with the free fatty acids (FFAs) conversion of 78.57%.
Microwave-method evidence: source values include 5.85 g, 328 W, 98.0 min, 78.57%, 77.63%. Entities: RSM-BBD, FFAs.
It takes 120.0 min to attain around 78.0% conversion of FFAs under 300 W microwave heating, while it takes about 540.0 min to reach about the same conversion by traditional heating.
Microwave-method evidence: source values include 300 W, 120 min, 78.0%, 540 min. Entities: FFAs.
In the case of using tubular NaA zeolite membrane, a high FFAs conversion of 97.11% is obtained... by in-situ water removal using spherical molecular sieve 4Å, the conversion of FFAs increases from 77.63 to 95.99% under the RSM optimized conditions.
Additional source evidence: source values include 5.85 g, 328 W, 98 min.
The microwave reactor (XH-200A, Beijing Xianghu Science and Technology Development Co., Ltd., Beijing, China) is used as the source of microwave radiation for transferring the energy to the reactants directly.
Additional source evidence: source values include 43.31%, 38.37%. Entities: FFAs.
Additional source evidence: source values include 95.99%, 97.11%.
Additional source evidence: source values include 78%, 96%.
