CONTINUOUS BIOCHAR KILN SYSTEM

Resumen de: WO2026110016A1

The continuous biochar kiln makes biochar from biomass. The continuous biochar kiln is continuously operated by using an updraft fire through a vertical rotating fire tube. The rotary fire tube is attached to a blade that acts as a conveyor or mixer. The blade conveys the biomass from the inlet to the outlet of the cylinder shape and air-tight kiln. As the biomass is conveyed it receives the heat transfer from the vertical rotating fire tube wherein the biomass transforms into biochar at the outlet valve through the process of pyrolysis. The pyrolysis combustible gas may be generated during the process and that gas becomes the thermal energy to continue fueling the kiln.

The system can provide alerts for deviations in fermentation rate and recommend interventions. Additionally, the system can monitor various stages of ethanol production, including liquefaction, oil separation, centrifugation, evaporation, and drying, using multiple accelerometers to determine process parameters such as viscosity, composition, and equipment performance.

BIOMASS PYROLYSIS-GASIFICATION DEVICE

Resumen de: WO2026109082A1

The present invention relates to the technical field of pyrolysis devices, and in particular to a biomass pyrolysis-gasification device, comprising a microwave heating reactor, a pretreatment mechanism and a driving mechanism, wherein the pretreatment mechanism comprises cutting mincer blades, which can push materials to gather towards the center during cutting; and the driving mechanism is configured to drive a cylinder to rotate about the horizontal axis and vertical center line thereof, such that the materials in the cylinder are in sufficient contact with the cutting mincer blades, whilst the materials gathered towards the center are dispersed outwards, thereby enabling the materials in the cylinder to repeatedly disperse and gather. In the present invention, the materials entering the cylinder are conveyed to the center part of the cylinder by means of the angled cutting mincer blades, whilst the driving mechanism drives the cylinder to rotate horizontally such that the materials entering the cylinder can be thrown away towards two ends of the interior of the cylinder under the action of centrifugal force. Thus, the materials can be repeatedly dispersed and gathered in the pretreatment mechanism, thereby achieving a more sufficient and comprehensive crushing processing effect.
