A Mathcad‐based educational experience to address the design of nonisothermal plug flow reactors
Cuadri Vega, Antonio Abad
; Gallego Calvo, Rocío; Martín Alfonso, María José; Delgado Sánchez, Clara; Cortés Triviño, Esperanza; Tenorio Alfonso, Adrián; Borrero López, Antonio María; Ortega Bravo, Francisco José (Wiley, 2022)
Mathcad is a simple-to-use and intuitive mathematical software that helps students to minimize the mathematical difficulties involved in solving engineering problems. The design of nonisothermal plug flow reactors (PFR) ... -
Impact of Vegetable Oil Type on the Rheological and Tribological Behavior of Montmorillonite-Based Oleogels
Martín Alfonso, María José; Rubio Valle, José F.; Hinestroza, Juan P.; Martín Alfonso, José Enrique (MDPI, 2022-08)
We formulated and characterized oleogels based on montmorillonite clay and vegetable oils that could serve as eco-friendly semi-solid lubricants. In particular, we studied the influence of the physical-chemical properties ... -
Influence of Formate Concentration on the Rheology and Thermal Degradation of Xanthan Gum
Martín Alfonso, María José; Mauricio Loaiza, Javier; Delgado Sánchez, Clara; Martínez Boza, Francisco José (MDPI, 2021)
Xanthan gum solutions have gained increasing interest for their use as environmentally friendly chemicals in the oil industry. Xanthan is compatible with most concentrate brines used for controlling formation damage and ... -
Modificación reactiva de betunes con prepolímeros basados en isocianato
(Universidad de Huelva, 2014)Los materiales bituminosos presentan una serie de propiedades, tales como ductilidad, adhesividad, resistencia al efecto de los factores ambientales y químicos, etc. Estas características permiten su utilización en el ... -
Oil-in-Oil emulsions of stearic acid dispersed in silicone oil with enhanced energy storage capability for heat transfer fluids
Delgado Sánchez, Clara; Partal López, Pedro; Martín Alfonso, María José; Navarro Domínguez, Francisco Javier (Elsevier, 2022-07-17)
Non-aqueous phase change emulsions are very unknown and promising multifunctional fluids consisting of phase change materials dispersed in carrier fluids, both being oily phases. The oil-in-oil phase change emulsions allow ... -
Rheological and tribological approaches as a tool for the development of sustainable lubricating greases based on nano-montmorillonite and castor oil
Martín Alfonso, José Enrique; Martín Alfonso, María José; Valencia Barragán, Concepción; Cuberes, María Teresa (Springer Open, 2020-10)
This study investigates the development of novel montmorillonite/castor oil blends to formulate sustainable lubricating greases to promote the replacement of petrochemicals industry-derived materials by substances obtained ... -
Thermal and Rheological Properties of Hydrophobic Nanosilica in Sunflower Oil Suspensions at High Pressures
Martín Alfonso, María José; Pozo Hernández, Javier; Delgado Sánchez, Clara; Martínez Boza, Francisco José (MDPI, 2021)
Nowadays, the reduction of the environmental impact associated with the operation of the oil industry is a primary concern. A growing trend is to develop low-toxicity formulations based on biodegradable components. In ...
