Biodiesel process intensification: the role of the liquid-liquid interface area in the achievement of a complete conversion in few seconds

Green Processing and Synthesis, 2012
Transesterification of vegetable oil with methanol, promoted by alkaline catalysts has been tested in many different reactors and surprisingly the reaction time, in some of these reactors, resulted very short, in the range of few seconds.

Application of the double optic probe technique to distorted tumbling bubbles in aqueous or organic liquid [PDF]

, 2005
The optic probe technique is widely used to investigate bubble reactors. To derive values of bubble local velocities and bubble local sizes, a specific signal treatment is usually applied under severe assumptions for bubble path and shape.
