Heterogeneous Two-Region Model for Low-Aspect-Ratio Fixed-Bed Catalytic Reactors. Analysis of Fluid-Convective Contributions
(American Chemical Society, 2014-02-21)
ABSTRACT: A two-region, two-dimensional (2R2D) model aimed at improving the heat transfer description of multitubular catalytic reactors is introduced here. The effects concentrated in the wall thermal resistance (1/hw) ...
Comparison between MAT flow fixed bed and batch fluidized bed reactors in the evaluation of FCC catalysts. 2. Naphtha composition
(American Chemical Society, 2009-07)
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) over ...
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, ...
Synthesis and characterization of CuCl2/SiO2 catalyst for the oxychlorination of methane
(Brazilian Association of Research and Development in Petroleum and Gas (ABPG), 2011)
Study of a multitubular fixed-bed reactor for ethylene production via ethane oxidative dehydrogenation
(Elsevier Science SA, 2008-12)
In the present contribution, a theoretical study of a multitubular fixed bed reactor for the ethane to ethylene oxidative dehydrogenation reaction over a highly active and selective Ni-Nb-O mixed oxide catalyst is presented. ...
Anaerobic co-digestion of vegetable waste and swine wastewater in high-rate horizontal reactors with fixed bed
(Elsevier B.V., 2016-06-01)
Considering the high waste generation that comes from agriculture and livestock farming, as well as the demand for natural gas, it is necessary to develop sustainable technologies which can reduce environmental impact. ...
A new device to select carriers for biomass immobilization and application in an aerobic/anaerobic fixed-bed sequencing batch biofilm reactor for nitrogen removal
(2016-12-01)
This study proposes a new approach to selecting a biofilm carrier for immobilization using dissolved oxygen (DO) microsensors to measure the thickness of aerobic and anaerobic layers in biofilm. The biofilm carriers tested ...
