    Abstract: 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.

    Abstract: It is disclosed a combustible article of manufacture comprising a treated lignin composition and a combustible support, wherein the treated lignin composition is attached to at least a portion of an external surface of the combustible support with a force greater than the force of gravity relative to the treated lignin composition. The treated lignin composition comprises solid lignin and has a moisture content in the range of 35% to 80% percent by weight. The combustible support is preferably a hardwood chip, but it may be also softwood chips, coal, coke, and shredded tires.
    It is also disclosed a fuel composition comprising a plurality of the combustible article.
