Abstract: Methods and devices are provided for hydrothermal pretreatment of lignocellulosic biomass. A mechanically simple and inexpensive vertical steam reactor is fed with biomass feedstock from the top, while pretreated material is removed from the bottom in steady-state by operation of moveable upper and lower restrictor means, which project across the reactor cross section when engaged. The vertical column of biomass is supported by the upper restrictor means. This is periodically withdrawn from the reactor cross section, permitting the column of biomass to fall by force of gravity onto the lower restrictor means. The upper restrictor means is then re-inserted, after which the lower restrictor means is withdrawn permitting a “plug” of pretreated material to be removed by force of gravity. Using biomass feedstock that has been compressed in a reciprocating piston press to bulk density of at least 500 kg/m3, which can be fed dry into the reactor using simple, inexpensive sluice systems and then wetted inside the reactor, this system provides comparable biomass throughput at a fraction of the cost of traditional commercial hydrothermal pretreatment systems used in “second generation” biorefining.

Abstract: Described herein are systems and methods for delivering catalyst to a reaction vessel. The methods include the use of a positive displacement reciprocating piston system having a catalyst delivery housing that contains a piston system. The piston system includes a top section, a bottom section, and a catalyst holding space between the top and bottom section such that the piston system is movable between a first and a second position to inject catalyst from the catalyst holding space into the reaction vessel when the piston system is in the second position and fill the catalyst holding space with catalyst from a catalyst feed supply when the piston system is in the first position.

Abstract: The present invention relates to a multistage stirred reactor, comprising a multiplicity of mutually adjacent reaction chambers and stirring elements for mixing the contents of at least one of the reaction chambers, wherein, between adjacent reaction chambers, there is in each case provided at least one opening that can be closed by means of closure means, such that in the open state there is a fluidic connection between the adjacent reaction chambers and in the closed state the adjacent reaction chambers are separated from one another. At least one of the closure means (300, 310, 320) is connected to an actuation rod (500, 510, 520) that is guided out of the stirred reactor. The actuation rod (500, 510, 520) can be moved back and forth between at least one first position and a second position, by rotation and/or displacement, wherein in the first position closure means (300, 310, 320) that are connected to the actuation rod (500, 510, 520) effect an open state of the opening assigned to them and in the second position closure means (300, 310, 320) that are connected to the actuation rod (500, 510, 520) effect a closed state of the opening assigned to them.
