World-leading services in process development, optimisation, and heterogeneous catalysis
Transparency and efficiency in delivering excellence
We work with a major multinational clientele in the chemicals and energy industries as well as leading research organisations. We value your data – all projects are performed under strict confidentiality.
International Customer Base
Over the last years, we worked for multiple customers including several major pharma and fine chemicals companies, petrochemical, aerospace, and research organisation.
The logos show only a small fraction of customers because most of the work is performed under the strictest confidentiality.
The expertise of Stoli in coatings helped us to develop new generation catalysts to improve one of our manufacturing processes.
Stoli scaled-up catalyst from grams to kilograms allowing us to complete a feasibility project.
Stoli Chem have performed a feasibility study and evaluated batch to continuous conversion for our process
Services: Catalysis
Catalyst Research
No task is too big or too small. We develop catalysts for fine chemical, oil & gas, and polymer industries.
Stoli Catalysts’ modular reactors combined with our rapid-testing facilities allow probing deeper into catalysts for a higher efficiency and selectivity. We create low-loading precious metal catalysts for high efficiency with excellent cost savings! Ask us about your new idea and discuss feasibility, piloting or scale-up projects.
Catalyst Coating
Catalysis in thin coatings eliminates heat and mass transfer limitations, creates new opportunities for intensified reactions and enhances product selectivity.
We are experts in catalyst coatings – conventional (sol-gel coating, grafting, evaporation) as well as proprietary (2 pending patents) techniques. Our catalyst-coated reactor tubes create enhanced productivity in lab-scale hydrogenation. Talk to us about your needs for catalytic coatings.
Kilogram-scale Catalyst Manufacture
Stoli has experience in lab to pilot-scale catalyst manufacture for fast execution of feasibility studies. We have developed and manufactured kilo-scale precious metal catalysts, bimetallic materials, zeolites and others. Talk to us about scaling up your idea.
Case studies: Catalysis
Temperature Programmed Oxidation of Cu Catalyst
We studied a Cu-based catalyst and correlated oxidation state of Cu with catalytic performance
Catalyst for fuel cell applications
We have developed a monolith-based fuel cell catalyst for sustainable remote energy generation.
Characterisation-directed kilo catalyst scale-up
We manufactured 10 kg catalyst using characterisation to validate the scale-up procedure from lab to manufacturing processes.
Cascading imine formation and hydrogenation
Stoli cascaded imine formation and hydrogenation; intensified process to maximise rate, and catalyst utilisation.
Developing a catalyst for a highly explosive reaction
After 100 long-term runs and building a bespoke reactor system to manage safety risks, we developed a stable catalyst with months at least 2 month lifetime.
Process intensification in hydrogenation
Short residence time and high temperature – an impossible combination for batch – allowed increasing specific reaction rates 8-fold in flow with the same product quality.

System Design, Modelling and Prototyping
With in-house rapid prototyping and 3D printing facilities, we can design and produce quality prototypes and models for testing. We are experts in process automation, modelling and computer aided design to help you at every stage of process or product development. Talk to us to streamline your route to market.
Proof of Concept Projects
Do you have an idea but are not sure if it works or is scalable? We translate ideas into reality whether you are developing a new chemical process, improving the heat exchange rate, scrubbing pollutants, or developing equipment for outer space exploration. We specialise in rapid prototyping and iteration, working closely with our customers.
Advanced Reaction Energy
We explore alternative energy sources for processes and develop radiofrequency (induction) and microwave heating systems to target the energy to the place it is required. We also work with non-thermal plasma processing to address the needs for more efficient and distributed processing systems.
