Conversion of biocrude and biomass to liquid hydrocarbons


The aim of the joint research project “BioKW” was to produce a CO2 neutral, sustainable supply of fuel based on biogenic raw materials using a combination of ablative pyrolysis and CLC processes in hot compressed water in the presence of heterogeneous catalysts.

Special aims: the synthesis and characterisation of suitable catalysts, the analysis of the starting materials, the product and in particular the construction of a pilot plant, the operation of the plant on a continuous basis and the marketing of the process principle.


Initially, the latest scientific and technical state of the art (2011) is to be determined by a further search of the literature and patents in order to supplement the existing literature database. A market survey as well as the drawing up of mass and energy balances was to be integrated in these papers (2011). Following the pilot plant was to be designed and the construction to be driven forward (2012). Further an analysis routine was to be drawn up for starting materials and products (2012). Continuous test runs (2012-2013) were to make up the main part of the project work. Extensive work on catalyst synthesis and characterization was to be carried out in connection with the test runs (2012-2013).


The PHÖNIX company is responsible for the design and construction of the plant.
