Abstract
将电解水、管式蒸汽重整和自热重整烃原料并行组合的制备合成气的方法。
Description
本申请涉及制备合成气。更特别地，在制备包含氢气和碳氧化物的合成气中，本发明并行组合电解水、管式蒸汽重整和自热重整，和任选另外的热交换重整烃原料。
制备合成气，例如对于甲醇合成，通常通过蒸汽重整烃来进行。
蒸汽重整的主要反应为(对甲烷给出)：
CH4 + H2O ⇆ 3H2 + CO
对于其它烃会发生类似的反应。蒸汽重整通常伴随着水煤气转换反应：
CO + H2O ⇆ CO2 + H2
蒸汽重整通常通过组合管式重整器(也称为蒸汽甲烷重整器，SMR)和自热重整(ATR)来进行，也称为一级和二级重整或二步重整。或者，可用独立的SMR或独立的ATR制备合成气。
ATR反应器的主要元件为燃烧器、燃烧室和包含在耐火衬里压力壳内的催化剂床。在ATR反应器中，烃进料被亚化学计量的氧部分氧化或燃烧，随后部分燃烧的烃进料流在蒸汽重整催化剂的固定床中蒸汽重整。由于高温，蒸汽重整也在一定程度上在燃烧室中发生。
在二步重整中，蒸汽甲烷重整器(SMR)必须大，并且需要大量的热量来驱动吸热蒸汽重整反应。因此，期望蒸汽重整器的尺寸和负荷能够减小。此外，二步重整概念中的ATR需要氧气。现今，这通常在低温空气分离装置(ASU)中产生。这个ASU的尺寸和成本很大。如果能通过其它方式产生氧气，这将是所期望的。
SMR产生超过合适甲醇合成气组合物所需要的氢气，而ATR产生较少量的氢气。
我们发现，当并行组合管式蒸汽重整和自热重整与电解水和/或蒸汽时，来自电解的氧气可用于ATR，而昂贵的ASU在制备合成气中变得多余。
同时，来自电解的氢气贡献出甲醇生产所需的氢气，这将允许向该过程加入另外的二氧化碳，从而仍产生甲醇合成所需的模数。
因此，本发明提供了制备合成气的方法，所述包括以下步骤：
(a)提供烃原料；
(b)通过电解水和/或蒸汽制备单独的含氢流和单独的含氧流；
(c)在管式蒸汽重整器中将来自步骤(a)的第一部分烃原料蒸汽重整成包含氢气、一氧化碳和二氧化碳的管式蒸汽重整气体；
(d)在自热重整器中用步骤(b)中获得的至少部分含氧流将第二部分烃原料自热重整成包含氢气、一氧化碳和二氧化碳的自热重整气流；
(e)组合来自步骤(c)的蒸汽重整气体与来自步骤(d)的自热重整气体；
(f)将来自步骤(b)的至少部分单独的含氢流加入来自步骤(a)的烃原料和/或加入来自步骤(c)的蒸汽重整气流和/或加入来自步骤(d)的自热重整气流和/或加入来自步骤(e)的组合的蒸汽重整气体和自热重整气体流；和
(g)提取合成气。
管式蒸汽重整在管式蒸汽重整中在来自燃烧器的烟气中产生CO2。在本发明的一个实施方案中，烟气中的CO2被回收并加到管式蒸汽重整过程。
因此，当在甲醇生产中利用添加的CO2时，有利地降低了根据本发明的方法的CO2足迹。
为了进一步使CO2排放最大限度地减少，可在管式蒸汽重整器下游的热交换重整器中热交换重整一部分原料，和/或可另外热交换重整管式蒸汽重整气体，以减少燃料消耗。
电解可通过本领域已知的各种方式进行，例如通过基于固体氧化物的电解或通过碱性电池或聚合物电池(PEM)电解。
当用于电解的电力(至少部分)由可持续来源产生时，通过所述方法生产的每单位产品的二氧化碳排放减少。
优选电解水和/或蒸汽只由可再生能源提供电力。
如上已描述，来自电解单元的所有氧气在步骤(d)中加到自热重整器，并且避免了通过分离空气制备氧气的ASU。
根据本发明的方法优选用于生产甲醇合成气。
甲醇合成气优选具有对应于1.90-2.20或更优选略高于2(例如2.00-2.10)的所谓模数(M=(H2-CO2)/(CO+CO2))的组合物。
因此，当根据本发明的方法用于制备甲醇合成气时，可以调整加到SMR或ATR上游的原料或加到步骤(e)下游的重整气体的氢气量，使得当氢气与由重整步骤产生的合成气混合，并且任选与从管式蒸汽重整器回收的CO2添加混合时，实现1.90到2.20之间或优选2.00到2.10之间的期望M值。
通常，用于本发明的各种实施方案的合适烃原料包括为原样的或经预重整的和/或脱硫的天然气、甲烷、LNG、石脑油或其混合物。
对于期望增加进料气中的氢浓度以及通过电解有利制备氢和氧的其它应用，也可采用根据本发明的方法生产合成气。
