Abstract:
The valorization of secondary streams such as extracted tannins and lignins is a key stage in the development of lignocellulosic biorefineries. Fast pyrolysis that converts biomass into a valuable liquid product is currently of particular interest for chemical production. However, conventional fast pyrolysis of thermoset biopolymers is technically complicate. Because of feeding issues, a new coating preparative method of the Pinus radiata feedstock was used to process a mixture of acid isolated lignin and sawdust (LI20) using the 0.1 kg/h fast pyrolysis plant scale (FP0.1kg/h). Although a slight decrease in total liquid and organics yields was recorded when pyrolyzing LI20, we managed to feed the lignin into the FP0.1kg/h without modifying its initial design while also increasing the amount of phenolics. Experimental conditions used at the small scale (2L glass beaker and FP0.1 kg/h plant) are currently being applied to the pilot scale (100L tank and FP10kg/h plant. The lignin-coated biomass material, LI20-5kg/h, was successfully prepared at large scale showing similar physico-chemical characteristics than LI20-0.1kg/h. The preliminary results obtained from the raw biomass pyrolysis at larger scale displayed lower liquids and organics yields with a substantial increase of the pyrolytic sugar fraction that was found detrimental to bio-oil stability.
