My research activities have a basis in the organic chemistry of naturally occuring organic compounds like petroleum and biomass, and primarily in an energy/geochemical context.  There is always some  analytical aspect.  Petroleum chemistry oriented projects cover the study of oil and gas generation and alteration including biodegradation and  relating petroleum composition with the physical properties of the phases - oil, gas and solid gas hydrates.  A paralell activity is to apply the established understanding of the natural geochemical transformation of biomass into petroleum to the conversion of “fresh” biomass to renewable fuels using pyrolysis technology.  Recently, I have become involved in the research on organic chemistry of extreme environments within the context the deep sea hydrothermal systems that are part of the research objectives of the new centre of excellence on Geobiology.

 

However, petroleum and biofuel related research still  is the major activity in my group. The methods used comprise a wide range of chromatographic techniques, with an emphasis on gas and liquid chromatography and IR and NMR spectrometry.  In addition we use preparative pyrolysis in petroleum maturation and biomass conversion studies.  Multivariate methods are essential for interpreting data in the studies of oil composition and properties, and experimental design and multivariate modelling is a core technique for optimising production of alternative fuels by pyrolysis of biomass and waste. 

 

Our research is has a strong interdisciplinary orientation, and projects and student supervision are largely based on cooperation with specialists in other fields. At present the cooperation is with the research group in petroleum microbiology at CIPR (Centre for Integrated Petroleum research), with the Oil and Gas unit at the StatoilHydro Research centers in Bergen and Trondheim, with the SINTEF Petroleum Research group in Bergen on the interactions between physical chemistry and chemical composition of oil, and an interdisciplinary project group administered by the PFI (Paper and Fibre Institute) in Norway on renewable fuels from biomass pyrolysis with Statoil and the forestry sector as industrial partners.

Kursundervisning: KJEM 230 Organiske analysemetoder og KJEM 203 Petroleumskjemi

Masteroppgaver blir gitt innen følgende forskningsområder

 1) Biodrivstoff fra lignin eller annen biomasse ved termokjemiske metoder:  Oppgavene går ut på å videreutvikle forståelse og praktiske løsninger for omdanning av fast biomasse til produkter i væskeform som kan brukes som komponenter i fornybare drivstoff.  I de siste årene har biopolymeren lignin vært det viktigste råstoffet, og ulike systemer for hydrodeoksygenering til fenoler og hydrokarboner har vært utviklet og testet.  Masteroppgavene innen dette feltet kan ha en hovedsakelig analytisk eller hovedsakelig syntetisk innretting, og gjennomføres gjerne i samarbeid med forskere i gruppen og/eller  eksterne bedrifter.  Hovedmetoder: Pyrolyse i trykkfast reaktor, forsøksdesign og multivariate tolkninger, kromatografiske og spektroskopiske analyser, massebalanser og karakterisering og vurdering av mulige anvendelser med hensyn til drivstoffkvalitet eller bruk som kjemisk råstoff.

 2) Petroleumskjemi:  Petroleum er en veldig komplisert blanding av organiske forbindelser som dannes ved en lagsom termisk nedbrytning av organiske rester som er innkorporert i kildebergarter.  Selv om petroleum ofte betegnes ”hydrokarboner”, er det også vesentlige mengder forbindelser med N,S og O-baserte funksjonelle grupper tilstede.  Disse gruppene bestemmer i stor grad egenskapene til oljefasen med hensyn til grenseflater i forhold til vann, gass og bergart.  Den kjemiske sammensetningen varierer også gjennom dannelsesprosessen, og som funksjon av mikrobiell nedbrytning av oljen.  Opprinnelse og sammenseting av slike forbindelser, og vekselvirkningen mellom kjemisk sammenseting og de fysikalske egenskapene til olje/vann/gass systemer - inkludert gasshydrater i fast fase -  gir fortsatt svært interesante problemstillinger i forhold til nye masteroppgaver.  Oppgavene kan være tverrfaglige innefor kjemi eller realfag generelt, og utføres ofte i samarbeid med eksterne forskningsmiljø.  Hovedmetoder:   Pyrolyse for simulert modning av olje og kildebergart, forsøksdesign og multivariate tolkninger, kromatografiske og spektroskopiske analyser, fysikalsk karakterisering av egenskaper i forhold til overflatekjemi. 

 3) Biogeokjemi/astrobiologi/”Livets opprinnelse”:  Historisk var ”liv” regnet som en forutsetning for å danne organiske molekyler, i den senere tid er det vist eksperimentelt at både enkle molekyler og forbindelser med høyere molekylvekt kan dannes fra uorganiske utgangsstoff under visse betingelser. En kritisk parameter er om det er reduserende betingelser i systemet slik at det blir tilgang på molekylært hydrogen, samtidig som det må finnes en  karbonkilde.  I tillegg krever reaksjonen ofte en katalysator, som for eksempel en redusert metalloverflate.  Slike betingelser finnes for eksempel i de varme undesjøiske kildene som er funnet på store havdyp på norsk sokkel de siste årene, hvor varme mantel-bergarter ligger nær havbunnen se http://www.uib.no/geobio .  De naturlige betingelsen i de dype hydrotermale feltene kan langt på vei reproduseres i laboratoriet, med reduserende betingelser og øket temperaur og eventuelt også høyt trykk, og vann eller superkritisk vann som reaksjonsmiljø.  Laboratorieforsøk under slike betingelser gir mulighet for en systematisk utforsking av parametre som kan påvirke reaksjonene som danner organiske forbindelser.  Prosjektene er gjerne tverrfaglige mot geologi i samarbeid med Senter for Geobiologi. Hovedmetoder: Eksperimentel etterligning av hydrotermale betingelser,  forsøksdesign og multivariate tolkninger, kromatografiske og spektroskopiske analyser, uorganisk karakterisering, termodynamisk modellering av stabilitet.

 4) Analyse av ulike materialer av særlig interesse:  Ulike oppgaver er mulige i spesielle tema.  For tiden er det en oppgave innen karakterisering av organiske molekyler innkorporert i dryppsteinsmaterialer med hensyn på mørkører for klima og vegetasjon. Projektene er et samarbeid med Stein-Erik Lauritzen ( Geovitenskap). Det er også en oppgave i analyse av arkeologisk materiale med særlig vekt på bindemiddel brukt i forhistorisk maling i samarbeid med Wenche Odden, Bergen Museum.  Hovedmetoder: Begge oppgavene vil bruke analytisk pyrolyse-GC-MS som en hovedmetode.
