    • A system and method for the calcination of minerals. The system comprises a vertically disposed reactor segment configured to impart horizontal forces on particles passing through the reactor segment in a vertical direction; an injector unit for receiving granular feedstock, the injector unit being disposed at a top portion of the reactor segment, whereby granules of the feedstock move through the reactor segment in a granular flow under at least one of a group consisting of a force of steam, gravitational force and a centrifugal force; a reactor heat exchange unit thermally coupled to a wall of the reactor segment for providing heat to the flowing granules inside the reactor segment through heat transfer through the wall of the reactor segment; one or more inlets formed in the reactor segment for introducing a superheated gas into the reactor segment to create conditions of a gas-solid multiphase system; and one or more exhaust openings formed in the retort segment such that gas products are at least partially flushed from the reactor segment under the flow of the superheated gas from the inlets to the exhaust openings.

    • Lignocellulose-containing materials are treated with lime (calcium hydroxide) and water at a relatively high temperature and for a certain period of time under certain conditions. The process variables were: lime loading which ranged from about 2 to about g Ca(OH).sub.2 /100 g dry material; water loading which ranged from about 6 to about 19 g water/g dry material; treatment temperature which varied from about 50.degree. C. to about 150.degree. C.; and treatment time which varied from about 1 to about 36 hours. The effects of treatment time and temperature were interdependent. A process for lime recovery is developed. The soluble Ca(OH).sub.2 was washed out of the pretreated material with water and converted to insoluble CaCO.sub.3, by reacting with CO.sub.2, and was thus separated. The CaCO.sub.3 can be heated to produce CaO and CO.sub.2. The CaO is hydrated to Ca(OH).sub.2 which can be reused as the lignocellulose treatment agent. Carbon dioxide is reused for lime recovery.
    • 含木质纤维素的材料在比较高的温度下用石灰(氢氧化钙)和水处理并在一定条件下处理一段时间。 过程变量为:约2至约g Ca(OH)2 / 100g干物料的石灰负荷; 水含量范围为约6至约19克水/克干物质; 处理温度从约50℃变化到约150℃。 治疗时间约1〜36小时。 治疗时间和温度的影响是相互依存的。 开发了石灰回收方法。 将可溶性Ca(OH)2用水从预处理物质中洗出,并与CO 2反应转化为不溶性CaCO 3,由此分离。 可以加热CaCO3以产生CaO和CO 2。 CaO与Ca(OH)2水合,可以作为木质纤维素处理剂再次使用。 二氧化碳重新用于石灰回收。
