PhD Transient Fischer–Tropsch Catalysis

Introduction
Are you fascinated by the challenges of the energy transition and catalytic conversion of carbon-based feedstocks? We are looking for a motivated PhD candidate to investigate how feedstock composition and catalyst structure affect performance during transient Fischer–Tropsch synthesis (FTS).
In this project, you will focus on understanding how variations in CO/CO₂/H₂ ratios and the presence of contaminants influence catalytic activity, selectivity (e‑naphtha to e‑wax), and long-term stability. By combining advanced kinetic studies with state-of-the-art operando characterization techniques, you will develop fundamental insights that enable improved catalyst and process design.
This project is embedded in the HyCarb consortium, where academic and industrial partners collaborate on advancing sustainable carbon conversion technologies under realistic operating conditions.

Job Description
Fischer–Tropsch synthesis is a key technology for converting synthesis gas into sustainable fuels and chemicals. However, in practical operation, feedstock composition can fluctuate, and impurities may be present, leading to transient catalyst behavior and deactivation. A fundamental understanding of these effects is currently lacking.

In this project, you will:

• Investigate the impact of feedstock composition - Conduct kinetic studies under varying CO/CO₂/H₂ ratios, in the presence of contaminants, and under transient operating conditions to quantify catalytic activity, product selectivity (e‑naphtha to e‑wax), and stability.
• Track catalyst state under realistic conditions - apply bulk operando and quasi-in situ techniques to monitor active phase evolution and structural changes during reaction.
• Link surface chemistry to catalytic performance - use advanced surface-sensitive methods, including near-ambient pressure XPS, DRIFTS, and SSITKA-DRIFTS-MS, to identify surface intermediates and correlate surface coverage with reaction kinetics.
• Develop advanced characterization workflows - establish robust methodologies for sampling, handling, and analyzing catalysts from long-term reactor operation without air exposure.

You will work closely with academic partners and industrial stakeholders to align experimental studies with realistic process conditions, feedstock variability, and application-driven objectives.

Job Requirements

• A master’s degree in chemical engineering, chemistry, or a related field
• Strong interest in heterogeneous catalysis and reaction engineering
• Experience with catalyst synthesis, characterization, or kinetic measurements is a plus
• Ability to work in an interdisciplinary team and collaborate with academic and industrial partners
• Fluent in spoken and written English (C1 level)

Conditions of Employment
A meaningful job in a dynamic and ambitious university, in an interdisciplinary setting and within an international network. You will work on a beautiful, green campus within walking distance of the central train station. In addition, we offer you:

• Full-time employment for four years, with an intermediate assessment after nine months. You will spend a minimum of 10% of your four-year employment on teaching tasks, with a maximum of 15% per year of your employment.
• Salary and benefits (such as a pension scheme, paid pregnancy and maternity leave, partially paid parental leave) in accordance with the Collective Labour Agreement for Dutch Universities, scale P (min. € 3,059 - max. € 3,881 gross per month).
• A year-end bonus of 8.3% and annual vacation pay of 8%.
• High-quality training programs and other support to grow into a self-aware, autonomous scientific researcher. At TU/e we challenge you to take charge of your own learning process.
• An excellent technical infrastructure, on-campus children's day care and sports facilities.
• Unlimited access to the modern on‑campus TU/e Student Sports Center at an exceptionally affordable rate.

PhD Catalytic Upgrading of Lignin-Derived Phenolics to Aromatics

Introduction
Are you excited about developing catalytic solutions for a circular chemical industry? We are looking for a motivated PhD candidate to work on converting lignin-derived feedstocks into valuable aromatics and specialty chemicals.
In this project, you will design and study catalytic processes that upgrade complex phenolic mixtures into targeted products using advanced bifunctional catalysts. By combining catalyst development, reaction engineering, and product analysis, you will contribute to new routes for turning renewable carbon into high-value chemicals.
The project is part of the collaborative research program HyFine, in partnership with academic and industrial partners, offering a unique opportunity to work on sustainable chemistry challenges with strong real-world relevance.

Job Description
Lignin valorization is a key challenge in the transition towards a circular and sustainable chemical industry. Depolymerized lignin streams contain complex mixtures of phenolic compounds that can serve as valuable feedstocks for specialty chemicals, yet efficient catalytic upgrading routes are still underdeveloped.
In this project, you will develop catalytic processes to convert lignin-derived phenolics into valuable aromatics and chemical building blocks. The research focuses on the selective demethoxylation and trans-alkylation of alkylmethoxyphenols using bifunctional catalysts.
You will perform catalytic experiments in continuous-flow reactors to evaluate activity, selectivity, and stability under realistic process conditions, and analyze both liquid- and gas-phase products to understand reaction pathways and overall process efficiency. Using a combination of model compounds and real lignin-derived feeds, you will investigate the influence of feed composition and operating conditions and apply systematic optimization strategies to maximize yields of desired products.
A key aspect of the project is understanding and improving catalyst stability, including identifying deactivation mechanisms and developing strategies for regeneration or improved catalyst design. The work will be carried out in close collaboration with academic and industrial partners within the consortium, ensuring strong alignment with upstream lignin processing and downstream application of the produced chemicals.

Job Requirements

• A master’s degree in chemical engineering, chemistry, or a related field
• Strong interest in heterogeneous catalysis, sustainable chemistry, and reaction engineering
• Affinity with catalytic conversion of biomass-derived feedstocks (e.g., lignin, phenolics) is highly desirable
• Experience with catalyst synthesis, catalytic testing, or analytical techniques is a plus
• A proactive, research-oriented mindset and motivation to tackle complex chemical systems
• Ability to work independently as well as in an interdisciplinary team
• Interest in collaboration with academic and industrial partners within a consortium setting
• Fluent in spoken and written English (C1 level)
