Abstract: A method for torrefaction of biomass using a torrefaction reactor vessel having stacked trays including: feeding the biomass to an upper inlet of the vessel such that the biomass material is deposited on an upper tray of a vertical stack of trays in the reactor; cascading the biomass down through the trays by passing the biomass through an opening in each of the trays to deposit the biomass on a lower tray; as the biomass moves around each of the stacked trays, heating the biomass material with an oxygen deprived gas; extracting moisture containing gas having passed through the biomass on the upper trays wherein the extraction is immediately below each of the upper trays; as the biomass undergoes torrefaction in the lower trays of the stacked trays, retaining the gas with the biomass until the biomass falls from the stacked trays to a pile of biomass in the reactor vessel; exhausting gases containing organic compounds volatized by the torrefaction of the biomass through a gas outlet on the vessel at an elevation between the stacked trays and the pile of biomass, and discharging torrefied biomass from a lower outlet of the torrefaction reactor vessel.

Abstract: A pressurized torrefaction reactor vessel including: a rotatable shaft extending vertically down from a top of the vessel; scraper devices each at a different elevation within the vessel and mounted to the shaft; a tray associated with each one of the scraper devices such that the scraper device is immediately above a tray of the tray assembly; wherein the tray is an open mesh and impermeable to passage of biomass through the tray; each tray includes a discharge opening to transfer biomass from the tray and down to a tray of a lower one of the tray assemblies, and wherein the discharge opening in the lowermost tray assembly transfers the biomass to a pile of the biomass in the vessel, and a bottom discharge port of the vessel through which the torrefied biomass is discharged.

Abstract: A method for torrefaction of Iignocellulosic biomass using a torrefaction reactor vessel having stacked tray assemblies comprising: continuously feeding the biomass to an upper inlet to the torrefaction reactor vessel such that the biomass material is deposited on an upper tray assembly of a plurality of tray assemblies stacked vertically within the reactor; as the biomass moves in the vessel while supported by a tray of each tray assembly, heating and drying the biomass material with a gas injected into the vessel, wherein the gas is substantially non-oxidizing of the biomass and is under a pressure of at least 3 bar gauge and at a temperature of at least 200°C; cascading the biomass down through the trays by passing the biomass through an opening in each of the trays to deposit the biomass on the tray of the next lower tray assembly; discharging torrefied biomass from a lower outlet of the torrefaction reactor, and circulating gas extracted from the reactor vessel back to the reactor.
Abstract translation: 一种使用具有堆叠的托盘组件的烘焙反应器容器烘焙异构纤维素生物质的方法，包括：将生物质连续地供给到烘焙反应器容器的上部入口，使得生物质材料沉积在堆叠的多个托盘组件的上部托盘组件上 在反应器内垂直; 当生物体在容器中移动时，同时由每个托盘组件的托盘支撑，用注入到容器中的气体加热和干燥生物质材料，其中气体基本上是非生物质的氧化，并且处于至少的压力 3巴规，温度至少为200℃; 通过使生物质通过每个托盘中的开口将生物质向下通过托盘，以将生物质沉积在下一个下托盘组件的托盘上; 从烘焙反应器的下部出口排出烘焙生物质，以及从反应器容器中提取的循环气体返回到反应器。
