Enzymatic synthesis of structured lipids from grape seed (Vitis vinifera L.) oil in associated packed bed reactors
(2020-01-01)
Triacylglycerols (TAGs) can be modified to increase the absorption of fatty acids, prevent obesity, and treat fat malabsorption disorders and metabolic diseases. Medium–long–medium (MLM)-type TAGs, which contain medium-chain ...
Thermophilic two-phase anaerobic digestion using an innovative fixed-bed reactor for enhanced organic matter removal and bioenergy recovery from sugarcane vinasse
(2017-01-01)
This study considered the application of anaerobic digestion (AD) with phase separation combined with the use of an anaerobic structured-bed reactor (ASTBR) as the methanogenic phase for the treatment of sugarcane vinasse, ...
Packed-Bed Photocatalytic Reactors. A Packing Structure Model and Its Experimental Validation with Computerized Tomography
(American Chemical Society, 2004-12)
A statistical model is proposed for the description of the spatial structure of a packed bed of spherical-like particles in terms of one- and two-bead distribution functions. This is the first step toward the full modeling ...
Comparison between MAT flow fixed bed and batch fluidized bed reactors in the evaluation of FCC catalysts. 1. conversion and yields of the main hydrocarbon groups
(American Chemical Society, 2009-03)
A comparison was performed between the performances of a MAT-type reactor (flow fixed bed) and a CREC Riser Simulator reactor (batch fluidized bed) in the conversion of two VGO feedstocks (aromatic and paraffinic types) ...

Supplement to the paper “Packed Bed Photocatalytic Reactors . A Packing Structure Model and its Experimental Validation with Computerized Tomography
(American Chemical Society, 2004-03)
The radiation field in photocatalytic packed beds results from direct energy exchange between the lamp and the catalytic beads, and from mutual exchange between beads that are close to each other. The statistical description ...
Evaluation of structural properties of cylindrical packed beds using numerical simulations and tomographic experiments
(De Gruyter, 2009-12-01)
This contribution is focused on the analysis of the structure of packed beds of spherical particles at relatively low aspect ratios (i.e., particle to tube diameter ratio) as those arising in multitubular fixed bed reactors. ...
Hacking biofilm developed in a structured-bed reactor (SBRRIA) with integrated processes of nitrogen and organic matter removal
(2021-01-01)
Biomass samples from a structured-bed reactor subjected to recirculation and intermittent aeration (SBRRIA) were analyzed to investigate the bacterial community shift along with the changes in the C/N ratio. The C/N ratios ...
Role of the catalyst in the pyrolysis of polyolefin mixtures and used tires
(American Chemical Society, 2017)
The role of polymeric structures and the presence of a catalyst in the pyrolysis of polyolefin mixtures and used tires was studied in a fixed bed reactor at 450 degrees C. Our results showed that while thermal pyrolysis ...
