Abstract
The present invention relates to a method and system for integration pyrolysis with gasification to increase the yield of saleable products from biomass feedstocks. By modifying the pyrolysis system to produce byproducts and reduce liquid yield, in conjunction with a hot-oxygen burner gasifier, the overall conversion efficiency of syngas per mass of biomass fed into the system is increased.
Claims14
A method for optimizing the conversion of biomass into saleable product derived from pyrolytic liquid and syngas, comprising:
- a) pyrolyzing a biomass feedstock in a pyrolysis reactor to produce pyrolytic liquid products, and byproducts including biochar, and biogas;
- b) gasifying the biochar and biogas along with the liquid products in a hot oxygen-based gasification system employing a hot oxygen burner to produce syngas;
- c) cooling the resulting syngas;
- and d) utilizing the syngas in a downstream syngas conversion process;
- wherein the pyrolysis process is optimized to increase the conversion efficiency of the biomass feedstock into byproducts and reduce the liquid yield such that the yield of syngas per mass of biomass fed into the integrated system is increased.
