screw retort for biochar production


The team was recently awarded a patent for their mobile biochar production and pelletizer system that has the capability to separate charcoal from the burning biomass using a mobile through-put method, or conveyor belt, that expels the biochar from the burner and quickly cools it.

Poplar pyrolysis produced bio-oil and biochar yields of 40.1% and 15.2%, respectively. Potato peel pyrolysis produced lower yield of bio-oil (22.7%) and higher yield of biochar (30.5%). A lab-scale pyrolysis auger reactor was developed at the University of Georgia ( Garcia-Perez, Adams, Goodrum, Geller, & Das, 2007 ).

The Basics of Biochar Production Batch kilns are typical of small scale biochar production and require all feedstock to be loaded at the beginning of the production cycle. Batch kilns can easily handle a variety of feedstock sizes. They are used when the production of biochar is the primary goal and recovery of by-products is secondary in ...

Tips for Biochar Production Drying and torrefaction processes require external energy. Wet feedstock needs more energy: use dry fuel (moisture content= 10% to 20%). do not over dry - it reduces yield and quality Screen feedstock into uniform particle size, 5-15mm if possible.

This staged process of thermo-decomposition has multiple advantages. First, it allows for the easy separation and processing of vapors produced into water, pyroligneous acid and burnable gases, as each are outgassed at successive temperature gradients. Second, a staged process is much more energy efficient.

Mike, I have never created biochar myself, but I had read that one of the main concerns is time consumption. This is a project more for personal education as I am an intern, so time is not much of an issue for me. We would like to capture the waste heat from this project, but our main objective is to create biochar and demonstrate to local farmers how they can do the same.

Two size fractions of biochar are produced: approximately 80% of material is approximately 1.5cm long by 1cm wide by .5cm thick, and about 20% of the material is a fine dust fraction on the order of 10s to 100s of microns. Example input and output rates of feedstock, biochar and energy are displayed in a table below.
