A system and a method for treating biomass with a gas includes at least one conduit having at least one biomass inlet and at least one biomass outlet, at least one gas inlet and at least one gas outlet. The system further includes a transport unit configured to move the biomass through the conduit from the at least one biomass inlet to the at least one biomass outlet thereby defining a biomass transport direction. The system is configured such that gas flowing from the at least one gas inlet to the at least one gas outlet crosses the biomass transport direction.

An advantageous process for pre-treating lignocellulosic biomass to hydrolysable polysaccharide enriched biomass with reduced amount of inhibitors of catalysis comprising steps of: providing a feedstock comprising cellulosic biomass; chopping of cellulosic biomass to have a cellulosic biomass feed material of uniform size; feeding of uniform sized feed material to a horizontal counter current extraction unit; removing excess of water from the feed material obtained from the extraction unit; soaking the extruded feed material obtained from the extraction unit; optionally removing excess of water from the feed material obtained after acid soaking; steam pre-treating the feed material obtained after removing excess of water from the acid soaked feed material; neutralizing the slurry obtained from the steam pre-treating; and optionally saccharifying the neutralized slurry.

It is disclosed an apparatus for separating a least one solid from a solids/fluid mixture, said apparatus comprising a separation chamber and a cushion chamber. The separation chamber comprises a top end, a bottom end, at least one wall, and an inlet port for introducing the solids/fluid mixture, said inlet port having an inlet port vector. The cushion chamber comprises at least one boundary wall, and it is adapted to maintain a cushion of the solids/fluid mixture at an intersection of the inlet port vector and the cushion chamber when the separation chamber and the cushion chamber are connected by a communication port at the intersection of the inlet port vector and the at least one wall. The communication port has an area at least a size of an impact area of the solids/fluid mixture on the at least one wall. The communication port may be formed by the erosion of the at least one wall of the separation chamber caused by the solids/fluid mixture at the impact area.

It is also disclosed a process for separating a solids/fluid mixture, wherein the solids/fluid mixture is introduced through the inlet port of the separation chamber and contacted with a cushion of a previously introduced solids/fluid mixture, the solids/fluid mixture being allowed to interact with the cushion of the previously introduced solids/fluid mixture. The at least one solid is separated from the fluid by density difference in the separation chamber. Preferably, the solids/fluid mixture is steam treated lignocellulosic biomass which is inserted in the disclosed apparatus at high velocity.

The invention relates to a method for treating biomass (2). In a step (S10), biomass (2) and an impregnation liquid are fed into a first reactor unit (10) such that the biomass (2) is impregnated with the impregnation liquid while the biomass (2) is transferred through the first reactor unit (10) by a conveyor means (11). In another step (S20), the impregnated biomass (2a) is transferred from the first reactor unit (10) to a separation unit (25), wherein at least a part of the impregnation liquid is separated from the impregnated biomass (2a) within the separation unit. In a step (S30), the separated impregnation liquid is discharged from the separation unit (25), such that a first part (26a) of the impregnation liquid is recirculated back to the first reactor unit (10). The invention further relates to a system for treating biomass (2).
