Bubble columns are the reactors of choice for conversion of synthesis gas to liquid fuels (F–T synthesis). The F–T synthesis is an exothermic reaction and cooling internals are installed in the bubble columns to remove the heat generated in the r

The present study compares typical measurements of bubble dynamics obtained with a 4-point optical probe over the same range of superficial gas velocity in the same size gas–liquid contactor in two different systems. The classical bubble column (BC

In the present work, a 4-point optical probe (Xue, J., Al-Dahhan, M., Dudukovic, M.P., Mudde, R.F., 2008a. AIChE J. 54, 350–36 3) was applied to a slurry bubble column to assess the effect of solids on bubble dynamics. All experiments were performe

A probabilistic model is introduced for correcting the directional sensitivity of the optical probe technique routinely used to determine gas holdup and bubble dynamics in gas-liquid systems. Measurements from optical probes oriented at various angle

In this work, we study CH 4 chemisorption over Pt-containing catalysts at low temperature (200–450 °C) in a fixed bed reactor. We report the systematic investigation of the effect of temperature, support (ceria vs. silica), and Pt content, on the

The reactor of choice for the Fischer-Tropsch synthesis is a slurry bubble column. One of the few disadvantages of bubble columns is the difficulties associated with their scale-up. The latter is due to complex phases’ interactions and significant

In the present work, a data-driven model for identification of flow regime in a bubble column is developed by combining data from optical probe technique and machine learning. Optical probe data from previous work was combined with new data in the pr
