PhD in natural corrosion inhibitors and green biocides for oil field applications (14-21077)

At the Faculty of Engineering and Science, AAU Energy, a position as PhD stipend is available within the general study program Energy. The PhD stipend is open for appointment from 1 November 2021, total 3 years.

Job description

Aalborg University contributes to the knowledge building of the global society as well as the development of prosperity, welfare and culture of Danish society. This is accomplished through research, research-based education, public sector services and knowledge collaboration. AAU educates students for the future and activities are based on a dynamic and transformative collaboration with the surrounding community. 

AAU Energy is a dynamic engineering research department in continuous growth and inspiring surroundings. AAU Energy has a very international environment and covers all areas of clean and sustainable energy systems of the future within electrical, thermal and mechatronic energy technology. AAU Energy has campuses in both Aalborg and Esbjerg, this position is located in Esbjerg. 

The mission is to be world leading in both research and research-based education of the energy engineers of the future. AAU Energy has approx. 300 employees of many nationalities, of which 25 are administrative staff. In addition, AAU Energy constantly has approx. 50-70 guest researchers from around the world. 

Research and teaching are in the absolute world elite in the field of energy, and we have extensive and leading workshop and laboratory facilities, where research and innovation are carried out in direct collaboration with industry to a great extent. 

The position is offered in relation to the research program "biogas and biorefineries" and the Ph.D. will be positioned at the Esbjerg Campus of Aalborg University. We work with finding technical solutions for sustainable and economic feasible production of biofuels. Key to this is chemical characterization of the biomass using e.g. HPLC, LC-MSMS, GC-MS. We are using several different processing methods to change the chemical structure of biomass in a way that enable us to chemically or microbially convert target components into fuel and value added chemicals e.g. natural biocides. Examples of processes are: solvent extraction, pyrolysis, hydrocracking, wet oxidation, hydrothermal treatment, enzymatic hydrolysis, and microbial fermentation. Finally, biorefinery design and modelling will be used to determine the best conversion processes for a given biomass.

The position will be part of a collaborative research project called “Halophilic plant extracts as natural corrosion inhibitors and biocides for oil field application “. The project aims to extracts and develop natural biocides/bioactive compounds from halophyte plants and test them on their effect in biofilm reactors. 

The Ph.D. study will include: extraction of the bioactive compounds form the biomass, chemical processing of the extracts, microbial tests of the produced antimicrobials, anaerobe bioreactor test, corrosion analysis, microbial community sequencing, and chemical characterization (HPLC, GC-MS, ICP-MS) of the produced extractives, plant fractions, and microbial metabolites. 

”The applicant must provide and upload a proper project description, which describes the applicants initial thoughts and ideas related to the specific project applied for. This includes a brief state-of-the-art (including short list of references), a time schedule and how the applicant intends to shed light on the project objectives. The project description should have a length of 4-5 pages.”

The candidate should hold a Master degree in Chemical Engineering, energy technology (bio-energy), biotechnology or similar fields and have experience in plant metabolites extraction and chemical characterization, microbial induced corrosion, and anaerob cultivation of mixed cultures.
