Abstract:
A high pressure/high temperature reactor was used in semicontinuous mode for hydroprocessing of Cracked Vegetable Oil (CVO). Therefore, hydrogen with a partial pressure of 50 bar was conveyed continuously through the pilot plant. The reaction temperature was 350 °C. This temperature was hold for 3 h in each experiment. CVO was provided in the reactor for treatment with a molybdenum catalyst with traces of heavy metals in a ratio of 1 wt.% corresponding to the mass of CVO in the reactor at the beginning of the test. Deoxygenation (DO) reactions were found in all experiments and Hydrogenated Cracked Vegetable Oil (HCVO) was obtained. Acid number and calorific value measurement as well as selectively gas chromatography/mass spectrometry (GCMS) was performed for proving DO. CVO used in this study was made from rapeseed oil. The aim of the project is the transfer of those findings to CVO which is based on used frying oil. Conventional raw materials suffer on a lack of sustainability and high cost. CVO removes these drawbacks and provides a high quality product with high energy density at the same time.
