Beer composition analysis: abundance evolution and characterization of beer flavor active compounds by GC-MS and determination of its ethanol concentration using MIR spectroscopy.
Martínez de Butrón Revuelta, Leire (2018-12-21)[EN] In this project the flavor and ethanol composition of a craft Pilsen beer provided by a micro-brewery called Boga will be analyzed. The first aim of this study is to identify the flavor active compounds found in ... -
Coke deposition and product distribution in the co-cracking of waste polyolefin derived streams and vacuum gas oil under FCC unit conditions
Rodríguez, Elena ; Elordi, Gorka ; Valecillos Díaz, José del Rosario; Izaddoust, Sepideh; Bilbao Elorriaga, Javier; Arandes Esteban, José María ; Castaño, Pedro (Elsevier, 2019-09)The effect of co-cracking of high-density polyethylene (HDPE) or its pyrolysis wax together with vacuum gasoil (VGO) has been studied. The aim is to determine the content, nature, and location of coke while analyzing the ... -

Energetic viability of a polyolefin pyrolysis plant
Elordi, Gorka ; Arabiourrutia Gallastegui, Miriam; Bilbao Elorriaga, Javier; Olazar Aurrecoechea, Martin (American Chemical Society, 2018-03)The energetic viability of a polyolefin pyrolysis unit that could be installed in a refinery plant was examined. Thermal pyrolysis at 500 and 700 degrees C, and the catalytic cracking by means of HZSM-5 and HY catalysts ... -
EPDM-zko norabide hauts babesle baten balioztatzea eta propietate fisiko-kimikoen eragina aplikazioan
Plaza Aguirre, Ainara (2020-01-16)[EUS] Lan honetan norabide hauts babesle jakin batzuen balioztapena burutu da. Piezen balioztapena, bezero batek eskatutako piezek bere funtzioa betetzeko dituzten propietateak egokiak direla baieztatzea da. Gainera, ... -
Evaluating catalytic (gas-solid) spectroscopic cells as intrinsic kinetic reactors: Methanol-to-hydrocarbon reaction as a case study
Valecillos Díaz, José del Rosario; Elordi Foruria, Gorka ; Cui, Mengmeng; Aguayo Urquijo, Andrés Tomás ; Castaño Sánchez, Pedro (Elsevier, 2022-12)Commercial spectroscopic gas-solid cell reactors are routinely used to analyze the dynamics of the catalyst (catalyst pelletized as a disc) structure and retained/adsorbed species using multiple operando techniques. These ... -
Lessening coke formation and boosting gasoline yield by incorporating scrap tire pyrolysis oil in the cracking conditions of an FCC unit
Rodríguez, Elena ; Izaddoust, Sepideh; Valecillos Díaz, José del Rosario; Bilbao Elorriaga, Javier; Arandes Esteban, José María ; Castaño Sánchez, Pedro; Epelde Bejerano, Eva; Elordi Foruria, Gorka (Elsevier, 2020-11-15)We have studied the effect of adding scrap tire pyrolysis oil (STPO) as feed or co-feed in the cracking of vacuum gasoil (VGO) using a commercial equilibrated catalyst. The cracking experiments were performed in a laboratory ... -
Poliolefinen pirolisia iturri-ohantze konikoan
Arabiourrutia Gallastegui, Miriam; Elordi, Gorka ; Olazar Aurrecoechea, Martin (Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2016)The amount of waste plastic increases every single year, which causes a critical environmental issue. Polyolefins (mainly high and low density polyethylene and poly- propylene) are the most common types of plastics, ... -
The intrinsic effect of co-feeding water on the formation of active/deactivating species in the methanol-to-hydrocarbons reaction on ZSM-5 zeolite
Valecillos Díaz, José del Rosario; Elordi, Gorka ; Aguayo Urquijo, Andrés Tomás ; Castaño Sánchez, Pedro (Royal Society Chemistry, 2021-02-21)Water is formed and added in the conversion of methanol-to-hydrocarbons, slowing down both the reaction and deactivation rates. This work aims to clarify the selective nature of water quenching on a ZSM-5 zeolite catalyst ... -
