PhD Project - Particulate formation and minimization from bio-diesel engines Combustion and Harmful Emission Control Research Centre Department of Chemical Engineering

A 3 year PhD position on the above mentioned topic is open at the CHEC (Combustion and Harmful Emission Control) Research Centre, Department of Chemical Engineering, Technical University of Denmark.

Supervisors: Professor Kim Dam-Johansen (, Associate Professor Peter Arendt Jensen (, Professor Anker Jensen (


To reduce the dependence on fossil oil, and reduce the net emissions of greenhouse gases, biofuels such as ethanol and bio-diesel may be used as transportation fuel. The full environmental influence of an increased utilization of bio transportation fuels is presently not known. A PhD project will therefore be initiated to investigate the influence of using bio-diesel or other liquid bio-fuels on gaseous and particulate emissions from diesel engines.

The objective of this PhD study is to quantify the influence of bio-diesel and diesel blends on the emission of particulates, hydrocarbons and NOx from engines, and thereby obtain improved knowledge on the particulate formation process as well as study the influence of the bio-diesel on catalytic filters. The project will be conducted in collaboration with other Danish research institutions.

Project content:

The study shall include experimental quantification of particulate formation and reduction in an engine, in the exhaust system and in a catalytic filter, as well as development of a model of the particulate reduction process. The experimental work may include some of the following tasks: Commissioning of test rig and measuring equipment, study of the influence of fuel properties and engine operation parameters on emissions, study of deactivation of the catalytic filters and supplement of engine test bench measurements with lab reactor experiments on the catalytic oxidation of hydrocarbons.

Contents of PhD application:

Candidates should hold a master degree in chemical engineering, or a similar degree with an equivalent academic level. Applications must include Curriculum Vitae, a statement on your motivation for applying, recommendations, and copies of all grade lists and other relevant diplomas.
