| Popis: | Second generation biofuel technologies are well investigated to extend the amount of sustainable biofuels. One of the most important criterions for biofuels is their profitability. The bioCRACK process is a new and innovative biomass-to-liquid concept to produce advanced biofuels by liquid-phase pyrolysis. A refinery integrated pilot plant was built up at the OMV refinery in Schwechat (Austria) to provide data for up-scaling. The objective of this publication was to test the suitability of different processed heat carrier oils derived from the bioCRACK process as feedstock for the FCC process. Vacuum gas oil – a typical feedstock for fluid catalytic cracking – was used as heat carrier oil. Different case studies were evaluated, whereas spruce wood and wheat straw were used as feedstock for pyrolysis. All experiments were conducted in a fully continuous small scale pilot plant with internally circulating fluidized bed design. In general, the obtained results show a high conversion efficiency for all performed case studies. Thereby the yield of coke is increased a little. The investigation confirmed that the total fuel yield can be improved even more by additional hydrotreatment. It turned out that the use of a pre-hydrotreated vacuum gas oil for pyrolysis leads to the highest conversion level. |
