    Abstract: The subject invention pertains to unique and advantageous systems for gasifying and/or liquefying biomass. The systems of the subject invention utilize a unique design whereby heat from a combustion chamber is used to directly gasify or liquefy biomass. In a preferred embodiment, the biomass is moved through a reactor tube in which all the gasification and/or liquefaction takes place. Preferably, char exits the biomass reactor tube and enters the combustion chamber where the char serves as fuel for combustion. The combustion chamber partially surrounds the reactor tube and is in direct thermal contact with the reactor tube such that heat from the combustion chamber passes through the reactor wall and directly heats the biomass within the reactor tube.

    Abstract: A high efficiency gasifier employs a rotary kiln having an indirect fired gasifier and a recycle system. The rotary kiln provides an essentially oxygen-free gasifying chamber into which raw feed material is introduced. Radiant tubes within the chamber transfer heat to the incoming raw feed material to pyrolyze it and convert it to char and product gas as the material advances toward the outlet end. The recycle system within the chamber returns both product gas and hot char to a receiving end of the kiln to aid in heat transfer to the raw feed material. The feed is thus heated more rapidly, and less heat input is required. Efficiency is further aided by providing additional residence time and gasification of the char.

    Abstract: A method and equipment for producing synthesis gas (S) from solid carbon particles (C), the carbon particles (C) being obtained by pyrolysis, gasification of the carbon particles (C) occurs by indirect heating of the carbon particles (C) in the presence of a process gas (P) in the same space where the carbon particles (C) are present, and the synthesis gas (S) generated during the gasification is discharged from the space. The method is characterised in that the carbon particles (C) and the process gas (P) are located in a reactor (1), and the indirect heating occurs by way of radiant heat from burners (Br1-Brn) located in the reactor (1).
