abstract = {Resource scarcity and global competition require the
optimization of existing and the development of efficient
novel chemical processes in short time. Chemical processes
use molecules as processing materials that strongly impact
process performance and thus play a crucial role in process
development and optimization. The performance of reactive
chemical processes is particularly influenced by molecules
such as reaction solvents and catalysts. Thus, such
molecules need to be selected with care. To identify optimal
molecules efficiently, computer-aided design methods are
desirable that automate the search for promising candidates.
However, currently available design methods for reaction
solvents and catalysts face significant limitations: These
methods typically consider small search spaces and evaluate
candidate molecules based on simplified kinetic models.
Additionally, most methods require extensive experimental
data to fit model parameters for specific reactions. To
overcome these limitations, this thesis presents novel
computer-aided molecular and process design (CAMPD) methods
that identify optimal reaction solvents and catalyst
molecules for reactive chemical processes. These CAMPD
methods employ advanced quantum chemical methods in
conjunction with transition state theory (TST) to predict
reaction kinetics without relying on the availability of
experimental data, even for catalytic reactions. Combining
this predictive power with an optimization-based molecular
design algorithm, large molecular design spaces are explored
efficiently to identify optimal solvent and catalyst
molecules. The proposed CAMPD methods evaluate every
designed molecule in an individually optimized chemical
process. As a result, the design inherently captures
relevant trade-offs between physicochemical properties and
accounts for mutual dependencies of optimal molecules and
process settings. The developed CAMPD methods are applied in
several case studies, including industrially relevant
auto-catalytic and catalytic processes. For all case
studies, the design methods identify promising molecules.
The presented results highlight the superiority of the
integrated molecular and process design compared to simpler
molecular design approaches. The developed CAMPD methods are
generally applicable to reactive chemical processes and
provide valuable tools for chemical process design and
optimization.},
