2 PhD positions on Pulping using deep eutectic solvents in Netherlands | Eindhoven University of Technology (TU/e)

The research of the group Separation Technology focuses on the design and development of novel extractants and adsorbents for highly selective affinity separations. We focus on the use of new hybrid materials (ionic liquids, deep eutectic solvents, metal organic frameworks) for this purpose. Areas of interest include the desalination of water, the separation/capture of carbon dioxide from gas mixtures, the recovery of valuable materials from (lignocellulosic) biomass and the separation of azeotropes. We use both experiments (at small and pilot-scale) and theoretical modeling for finding improved separation methods.

Two PhD positions are open in the field of pulping with novel solvents:

Pulping using deep eutectic solvents

The aim of both PhD projects is to develop a new class of renewable solvents, so-called deep eutectic solvents, for pulp and paper processing. Deep eutectic solvents are mixtures of two or more nature-based compounds that have melting points above 100 oC and are solid at room temperature (such as glucose and malic acid). However, when you mix these compounds, they form a liquid phase at room temperature with very low volatility. These liquids offer opportunities for use as energy-efficient omnivore pulping solvents.

One PhD student will focus on the delignification of various biomass sources, while the other student will focus on other separations (cellulose and hemicellulose purification) in the pulp and paper industry using deep eutectic solvents. First, you will do an experimental-modeling solubility study of biopolymers (lignin, cellulose, hemicellulose) in the novel solvents. Thereafter, you will apply the novel solvents as extractants for various separation processes (delignification, cellulose purification). Next, the recovery of pulp and lignin is addressed, and possible options for the recovery of the deep eutectic solvent will also be investigated. Finally, an economical and environmental evaluation of the use of deep eutectic solvents for pulping processes and a comparison with the current process will be made.

Requirements

We are looking for a talented and enthusiastic (almost) graduated Master student in Chemical Engineering or Chemistry, preferably with a background in process engineering, pulp and paper engineering or separation technology. Other requirements are excellent analytic and communicative skills. You are fluent in English and you are a team player.

Conditions of employment

We offer a challenging job for four years in a highly motivated team at a dynamic and ambitious University and in collaboration with 14 large pulp and paper producers across Europe. You will work with innovative analytic equipment and you will be part of a highly profiled multidisciplinary collaboration where expertise of a variety of disciplines comes together. The TU/e is located in the smartest regions of the world en part of the European technology hotspot 'Brainport Eindhoven'; well-known because of many high-tech industries and start-ups. A place to be for talented scientists!

The gross monthly salary in accordance with the Collective Labor Agreement of the Dutch Universities (CAO NU), starts with € 2083 in the first year to € 2664 in the fourth year. Besides this the TU/e has holiday- and end-of the year allowances, an excellent package of attractive benefits for employees, a child-care facility, and a modern sports complex. Assistance for finding accommodation can be given. Especially for PhD students the TU/e also offers opportunities for personal development. We do this by offering every PhD student a series of courses that are part of the Proof program as an excellent addition to your scientific education.
