Herbert Loria, Auteur ; Pedro Pereira-Almao, Auteur |The direct application of nanoparticles as nonsupported adsorbents and catalysts is of high interest since they offer high surface areas with reduced mass transfer limitations. However, the natural tendency of these materials to aggregate, even [...]

Carmen E. Galarraga, Auteur ; Carlos Scott, Auteur ; Herbert Loria, Auteur |Typically, the catalytic upgrading of heavy fractions (VGO and VR) has been studied using mostly conventional supported catalysts at temperatures and pressures higher than 400 °C and 6 MPa, respectively. This work focuses on the upgrading of hea[...]

Herbert Loria, Auteur ; Pedro Pereira-Almao, Auteur |The deposition of solid particles in cylindrical channels has received considerable attention, because of its direct application in industry. However, an adequate mathematical expression that studies the separation and suspension of dispersed pa[...]

Herbert Loria, Auteur ; Pedro Pereira-Almao, Auteur |As light oil reserves dwindle, the extraction and processing of heavy crude oils are becoming increasingly important. The use of ultradispersed catalysts (nanometric catalytic particles dispersed in the oil) is considered to be a promising way t[...]

Herbert Loria, Auteur ; Pedro Pereira-Almao, Auteur |An innovative way to upgrade heavy crude oils is the use of ultradispersed catalysts; however, an adequate mathematical expression that describes the mass transfer on this process is still missing. This paper studies the separation and suspensio[...]

Herbert Loria, Auteur ; Pedro Pereira-Almao, Auteur ; Marco Satyro, Auteur |Density and viscosity are important quantities required in engineering design for production, fluid transportation, and processing. However, there is no satisfactory theory for the calculation of these properties for bitumen. The principal objec[...]
