    Abstract: Described herein is a material moving apparatus that includes a chamber into which a compressible material is introduced. The chamber includes an input opening for receiving the material, a discharge opening and a sealing mechanism to prevent flow of air or other gasses between the input opening and the discharge opening. In one embodiment, the material moving apparatus can be used to introduce compressible biomass into a gasification reactor.

    Abstract: The reactor pump for hydrolytic splitting of cellulose is configured to pump cellulose, under high pressure, with low availability of sugar into a reactor. The reactor has an upstream transition segment connected to a downstream reaction chamber. The transition segment has an inlet that is smaller than the outlet. The inner walls taper outward. The chamber has an inlet that is larger than the discharge outlet. The inner walls taper inward. The transition segment outlet has an area that is substantially the same as the area of the chamber inlet. Back pressure in the chamber forms a cellulose plug within the inlet of the transition segment. The plug stops cellulose from escaping out the inlet. High pressure pumping forms a cellulose plug within the discharge outlet of the chamber. The plug slows downstream movement of the cooking cellulose giving the cellulose time to cook. Cooking cellulose begins to breakdown under heat and the injection of acid, if required. The outer surface of the plug is cooked faster than the inner core and in the process the faster cooking portion of the plug becomes a liquefied slurry. The slurry lies between the inwardly tapering chamber walls and the less cooked inner core. The slurry slides faster towards the discharge outlet than does the inner core. As the slurry moves downstream in the chamber, the surface of the inner core moves to the walls and in turn is liquefied. Cellulose may be pre-treated prior to entry in the reactor by the addition of water and a weak acid such as sulfuric or ammonium. The cellulose may be granulated to provide more surface area to assist break down in the reactor.

    Abstract translation: 用于纤维素水解分解的反应器泵被配置为在高压下泵送纤维素，糖的可用性低到反应器中。 反应器具有连接到下游反应室的上游过渡段。 过渡段具有小于出口的入口。 内壁向外逐渐变细。 该室具有大于排出口的入口。 内壁向内逐渐变细。 过渡段出口具有与室入口的面积基本相同的区域。 室中的背压在过渡段的入口内形成纤维素塞。 塞子阻止纤维素从入口逸出。 高压泵送在室的排出口内形成纤维素塞。 塞子减慢了烹调纤维素的下游运动，使纤维素的时间变得烹调。 如果需要，烹饪纤维素在加热下开始分解并注入酸。 插塞的外表面比内芯更快地烹饪，并且在该过程中，插头的较快烹饪部分变成液化浆料。 浆料位于向内变细的室壁和较不熟的内芯之间。 浆料比内核向排出口滑出更快。 当浆料在室中下游移动时，内芯的表面移动到壁上，并且进而液化。 纤维素可以在通过加入水和弱酸如硫酸或铵进入反应器之前进行预处理。 纤维素可以被造粒以提供更多的表面积以帮助在反应器中分解。

    Abstract: An on-line device for predicting at least one fluid flow parameter in a process includes structure and/or function whereby a flow domain has disposed therein a pre-determined portion in which a fluid flows. Preferably, the device includes a computer having: (i) a memory for receiving a database, the database including relative information in respect of a plurality of nodes or a plurality of particle pathways in the pre-determined portion; (ii) structure to receive input data from the process, and (iii) structure to calculate the at least one fluid flow parameter from the database and the input data. The device is particularly advantageously employed as a UV dosimeter.

    Abstract: A liquid separator apparatus to extract liquid, usually water, from a water-solids mixture. The apparatus includes liquid separator device with a housing with an inlet and an outlet separated by a liquid extraction chamber. The housing sidewalls defining the extraction chamber are porous, and are preferably comprised as a plurality of spaced apart slats. The slats can be movable inwardly and outwardly relative to the housing in order to vary the volume of the extraction chamber. A transfer pipe has an outlet end connected to the inlet of the separator device. The transfer pipe is closed-walled and has an inlet end connectable to a solids material moving apparatus such as a solids pump for movement of a water-solids mixture through the transfer pipe into the liquid separator device. A source of air under pressure such as an air compressor introduces compressed air into a side wall of the transfer pipe to accelerate removal of water from the water-solids mixture.
