    • A stacked plate chemical reactor in which simple plates, each incorporating no surface features other that an opening, are stacked together. When openings in adjacent plates are properly aligned, a fluid pathway is defined between inlet ports for each chemical reactant and an outlet port for a chemical product. In one embodiment of the invention, sixteen simple plates are stacked to provide a reactor incorporating three heat transfer fluid pathways, two reactant fluid pathways, one product fluid pathway, multiple mixing chambers, multiple reaction chambers, two reactant pretreatment heat exchangers, two reaction chamber heat exchangers, and multiple temperature sensor pathways. Precise dimensional control of the reactant fluid pathway height enables stacked laminar flow paths for the reactants to be achieved, allowing efficient and rapid diffusion mixing to occur. Because the simple plates incorporate no features other than openings, fabrication of such plates is easily achieved. Different reactor designs, having additional reactant pathways, more or fewer heat transfer fluid pathways, more or fewer heat exchangers, more or fewer mixing chambers, more of fewer reaction chambers, and more or fewer sensor pathways can readily be achieved by adding or removing plates from the stack, and or by changing the pattern and number of openings in the simple plates that are used. The simple plates can be field in the stack during use of the chemical reactor using pressure exerted on opposite outer simple plates of the stack, or can be permanently joined. A preferred material for the fabrication of the plates is stainless steel, although other materials such as glass, plastic, and other metals can alternatively be used, which are compatible with the selected reactants and the desired product.
    • 堆叠板式化学反应器,其中每个不具有开口的表面特征的简单板堆叠在一起。 当相邻板中的开口正确对准时,在每个化学反应物的入口和用于化学产品的出口之间限定流体通道。 在本发明的一个实施方案中,堆叠十六个简单的板以提供一个结合有三个传热流体路径,两个反应物流体路径,一个产物流体路径,多个混合室,多个反应室,两个反应物预处理热交换器,两个反应室 热交换器和多个温度传感器通路。 反应物流体通道高度的精确尺寸控制能够实现用于反应物的堆叠层流路径,从而允许发生高效和快速的扩散混合。 由于简单的板不包含开口以外的特征,所以容易实现这种板的制造。 不同的反应器设计,具有额外的反应物途径,更多或更少的传热流体途径,更多或更少的热交换器,更多或更少的混合室,更多的更少的反应室和更多或更少的传感器通路可以容易地通过添加或去除板 并且或通过改变所使用的简单板中的开口的图案和数量。 在使用化学反应器的过程中,简单的板可以使用施加在堆叠的相对的外部简单板上的压力,或者可以永久地连接在堆叠中。 用于制造板的优选材料是不锈钢,尽管可以替代地使用其它材料如玻璃,塑料和其它金属,其与选择的反应物和所需产物相容。
