Bio-Oil Production by Pyrolysis and Liquefaction of Biomass Using Blast Furnace Slag as Heating Source

In this paper, a novel biomass pyrolysis and liquefaction system using blast furnace as heating source was presented. The system is composed of three parts: blast furnace slag granulation, biomass pyrolysis centrifuge reactor, and the waste heat of blast furnace as the heat source. As the cost of biomass pyrolysis was greatly reduced, this system has a promising application prospect.

Slag Waste

Based on the comprehensive experimental test-bed of blast furnace slag waste heat recovery, we study the impacts which are caused by the changes of the key parameters, such as blast furnace slag discharged temperature, the speed of the granulation device, on the particle diameter distribution and sphericity, so as to master the best operating parameters of the blast furnace slag dry granulation, and provide experimental basic materials for blast furnace slag waste heat recovery. The results show that: when the discharged temperature of the blast furnace slag is controlled in 1400°C～1450°C, and the speed of the granulation device is controlled above 2000r/min, the sphericity is better, and 80% of the particle’s diameter will be 2～5mm.
