The content of these courses can be
adjusted to suit local requirements.
Characterization, Measurement
and Modelling of Catalyst Decay.
A series of five 1-hour lectures plus a
1-hour tutorial review for postgraduate students who are undertaking research
projects in heterogeneous catalysis. The
course is also suitable for industrial training of new recruits (chemists and
chemical engineers). Some problems will
be set for consideration between lectures and these will be considered in the tutorial.
The course was first presented to post-graduate students from
Learning
Objectives: basic understanding of the main mechanisms of catalyst
decay; diagnosis of the causes of catalyst decay from reaction data and
analytical characterization; insight into the measurement and modelling of
catalyst decay.
Typical Synopsis.
Lectures 1 and 2. Introduction. Basic concepts in applied heterogeneous catalysis. Background
to catalyst decay: industrial importance, economics, timescales. Mechanisms of catalyst decay and their characterisation. Sintering of metal particles and supports, phase transformations,
poisoning, fouling including carbon deposition (coking).
Lectures 3 and 4. Kinetics of
catalyst decay. Decay models:
empirical and mechanistic.
Influence of reactor profiles. Impact of pore-resistance. Monitoring
catalyst performance.
Lecture 5. Case
study on modeling catalyst decay. Summary and Conclusions.
Industrial
Catalyst Decay.
This course is primarily aimed at
industrial scientists (chemists or chemical engineers) who are engaged in
process support and/ or catalyst research.
It consists of two sections which can be taken separately or combined to
make an extended course. Each part
consists of a 2-hour lecture (or two 1-hour lectures) plus optional sessions
for case-histories and/or problem solving.
The content of part I was developed originally for internal company
workshops within ICI and was later presented as a plenary lecture at the 1st
NICE Workshop on Catalyst Testing and Characterisation (June 1997, DECHEMA,
Frankfurt-on-Main, Germany). The case study was developed for a module of the Integrated
Graduate Development Scheme (IGDS) at the
I Monitoring the Performance of Process
Catalysts
This section has already been presented
to scientists and chemical engineers engaged in the manufacture and use of
heterogeneous catalysts within major companies in

II Measurement and Modelling of Catalyst Decay
This section includes a detailed
examination of research techniques for the investigation,
measurement and modelling of catalyst decay at research, pilot and plant scale and
includes techniques for accelerated decay.
