Latest Patents
Weirich's latest patents include innovative methods for the rapid pyrolysis of lignocellulose. One of his patents describes a method that involves mechanically comminuting lignocellulose into particles, followed by drying and preheating these particles. The process includes mixing the lignocellulose particles with heat transfer particles, which are heated to a temperature between 500°C and 650°C. This mixture is then subjected to pyrolysis in an oxygen-excluded reactor, achieving temperatures between 400°C and 600°C for a duration of 1 to 50 seconds. The result is the production of pyrolysis coke, pyrolysis condensate, and pyrolysis gas.
Another significant patent focuses on producing and preparing fast pyrolysis products from biomass for entrained-flow pressure gasification. This method involves heating biomass in a pyrolysis reactor under oxygen exclusion, establishing a temperature range of 400°C to 600°C for a similar time frame. The process yields porous pyrolysis coke, pyrolysis condensate, and pyrolysis gas, with subsequent condensation stages to separate various components.
