Bio Fuels from Fluid Catalytic Cracking by co processing and processing pure bio oils in circulating fluidized bed


Wir bitten um Verständnis, dass die Informationen über dieses Projekt derzeit nur in englischer Sprache verfügbar sind.



Oils from renewable biological sources are gaining in importance in response to decreasing crude oil reserves and subsequently increasing oil prices. Therefore an investigation was carried out into the possibility of adding oils from biological sources to the feedstock of FCC (Fluid Catalytic Cracking) processes. The purpose was to produce fuels in the diesel and gasoline boiling range and light hydrocarbons for the petrochemical industry.


The experiments were conducted in a continuously operated pilot-scale FCC-unit with internal CFB-design and focused on a thorough analysis of the basic applicability of these oils in a FCC-unit in terms of cracking reactions and subsequent effects on catalyst circulation and obtained product distribution. Special consideration was given to the effect of the bio oils on the octane numbers of the obtained products in the gasoline boiling range. The applied bio oils, rapeseed oil, soy oil, palm oil and sunflower oil, were added to hydrated vacuum gas oil (standard FCC-feed) in different concentrations ranging up to 100 mass percent. The different experiments were conducted as continuous test runs and results were compared with the base case operation, using 100% vacuum gas oil.
Based on a lot of experimental Data a model for simulating the FCC and OCP (Olefin Cracking Process) was developed. The methods used for the modelling comprise the Multiple Linear Regression (MLR), the Principle Component Analysis (PCA), and the Principle Component Regression (PCR).
