A study into the composition and processability of different biomass feedstocks has found sunflower seed husks and poplar wood slabs to be the most suitable for producing bio-based products via fast pyrolysis conversion. The study was conducted by Capax Biobased Development and BTG Biomass Technology Group as part of the Horizon 2020 project Bio4Products, which is testing the feasibility of a fast pyrolysis based biorefinery concept.

A shortlist of 10 feedstocks were studied, focusing on residues from agriculture, food/feed processing and forestry: Hemp shives, Flax shives, Flax pellets, Wheat straw, Olive kernels, Sunflower husks, Poplar wood slabs, Softwood, Hardwood (poplar) and Phytoremediated poplar wood. These feedstocks were selected based on a previous study into biomass availability as well as their suitability for processing and sustainability parameters.

Capax - Properties - Feedstock - Particle - Size

Capax first investigated the physical properties of each feedstock including particle size and moisture content. This was followed by a chemical characterization, analyzing lignin/cellulose/hemi-cellulose ratio, and ash and mineral content.

To analyze the effect on quality and yield of fast pyrolysis...
