“…Their research improved our understanding of the dynamics of power consumption in the reactor system. In their work, Jafari et al 46 investigated the correlation between the power number of a self-inducing impeller and the Reynolds number at various speeds. The power number has a negative correlation with the Reynolds number as it increases.…”

Packed tower reactors, mechanically stirred reactors, airlift reactors, and gas-self-inducing reactors are frequently utilized among the various types of reactors. Self-inducing reactors exhibit notable advantages owing to their simple structure, effective gas–liquid intermixing, and low energy requirements, rendering them highly suitable for bioengineering endeavors. The purpose of this analysis is to shed light on the use of self-inducing reactors in bioengineering by examining the following five parameters: critical speed, suction rate, volumetric mass transfer coefficient, power characteristics, and gas hold-up. Through a comprehensive analysis of the advancements achieved in these domains, it is possible to determine the challenges and opportunities that lie ahead in the realm of bioengineering.

Oxidative Hydrolysis of Cellobiose to Glucose

et al. 2011

Cellobiose hydrolysis into glucose was chosen as a model system for cellulose breakdown to investigate glycosidic bond cleavage. The hydrolysis was enhanced by increased acidity in an inert gas medium, while air-assisted hydrolysis with a neutral solution achieved over 70% glucose yield. Hydrogen peroxide, as a stronger oxidant than air, converted cellobiose to carboxyl compounds, which lowered the glucose selectivity. At 150°C, the selectivity from cellobiose to glucose was very low on porous c-Al 2 O 3 supported catalysts, even lower than without a catalyst. When the active metals were prepared on non-porous supports such as spherical alumina (a phase), the overall yield of glucose was dramatically improved at 120°C. Similar improvements were obtained for another disaccharide model, sucrose, which achieved greater than 90% sucrose conversion with selectivity in excess of 90% at 80°C.
