A
transient operation has been previously considered in many industrial processes where either heat recovery or production
rate can be considerably improved as compared to steady-state operation. The effect of periodic temperature oscillations
has been studied in the hydrogenation and isomerization of D-glucose over a supported Ru-catalyst in a micro trickle bed
reactor. It was found that the preferred reaction pathway depends on the frequency of periodic temperature oscillations.
The catalyst based on ruthenium nanoparticle supported over hypercrosslinked polystyrene was tested in the reaction of
hydrogenation/isomerization of glucose and maltose under radiofrequency heating in a continuous flow fixed bed reactor. The
catalytic activity and selectivity were investigated under the steady-state and transient operation reactor modes. The transient
operation of periodic temperature oscillations with a low amplitude of 14
o
C showed a dramatic change in the reaction pathway
altering the preferential reaction from hydrogenation to isomerization for both substrates studied. The period of temperature
oscillations affects the hydrogen coverage which can determine the main reaction which takes place. The data shows that
the transient operation mode could have a high impact on biorefinery because fructose is one of the main feedstocks for
5-hydroxymethylfurfural and other valuable compounds in the field. Moreover, the work demonstrates that a concept of a
superior product selectivity achieved by introducing transient operation, which can likely be applied to other reaction classes
and processes.
Biography
Dr Javier Fernandez-Garcia studied his bachelor (2002-2007) and master’s degree (2010-2011) in Spain. He worked in industry from 2007 to 2014 in companies
such as Saint-Gobain, XSTRATA, Biogas Fuel Cell and HUNOSA. He completed his PhD at University of Oviedo (2011-2014). After that he worked as a Research
Fellow at University of Warwick from 2014 to 2016. Then he developed research activities in Stoli Catalysts Ltd (Spin-out company) and he was finally appointed
as Lecturer in Chemical Engineering at University of Leeds in 2017.
