The organic-inorganic hybrid perovskite CH3NH3PbI3 has attracted significant interest for its high performance in converting solar light into electrical power with an efficiency exceeding 20%. Unfortunately, chemical stability is one major challenge in the development of CH3NH3PbI3 solar cells. It was commonly assumed that moisture or oxygen in the environment causes the poor stability of hybrid halide perovskites, however, here we show from the first-principles calculations that the room-temperature tetragonal phase of CH3NH3PbI3 is thermodynamically unstable with respect to the phase separation into CH3NH3I ＋ PbI2, i.e., the disproportionation is exothermic, independent of the humidity or oxygen in the atmosphere. When the structure is distorted to the low-temperature orthorhombie phase, the energetic cost of separation increases, but remains small. Contributions from vibrational and configurational entropy at room temperature have been considered, but the instability of CH3NH3PbI3 is unchanged. When I is replaced by Br or CI, Pb by Sn, or the organic cation CH3NH3 by inorganic Cs, the perovskites become more stable and do not phase-separate spontaneously. Our study highlights that the poor chemical stability is intrinsic to CH3NH3PbI3 and suggests that element-substitution may solve the chemical stability problem in hybrid halide perovskite solar cells.

氢气是炼油厂加工烃类和提高油品质量的重要原料气,但是在工业上氢气的制备成本高,其主要来源于化石资源。在石油炼制过程中,会产生大量富含氢气和烃类等高价值组分的炼厂气,常被作为燃料气直接燃烧,造成了严重的资源浪费。因此,利用高效的分离方法和工艺设计,从炼厂气中回收氢气是近年来重要的提高氢气利用效率的方法。但是,炼厂尾气存在来源复杂、多组分、分离方法多等特点,确定合适的分离方法和优化的分离序列十分困难,因此存在“组合爆炸”的问题。基于以上问题,本论文基于三角坐标-矢量分析的图形设计法,得到了10股炼厂气综合回收的优化分离序列流程和设计方案,基于流程模拟,结合灵敏度分析和响应面法,对其过程参数进行优化,以及对整个过程系统进行技术经济评价,实现了氢气、轻烃等资源组分的高效回收。首先,在三角坐标系下,以组分的产品归属及分离性质相似程度为合并法则,将原料简化为燃料气、氢气和轻烃构成的三元体系,将来自中国某石化公司的10种股不同成分的炼厂尾气标注在三角坐标体系中。根据炼厂气组成的特点,将位于三角坐标系同一分离单元优势区域的原料气进行合并,得到两个混合物流,分别落在变压吸附(PSA)分离区的F1和浅冷(SC)分离区的F2。基于该两个混合原料物流,通过绘制对应的分离单元矢量对,依次确定对应的分离方法,得到最终的包含浅冷(SC)、氢气膜分离(GPm)、轻烃膜分离(RPm)和变压吸附(PSA)四种技术的梯级耦合回收工艺。最后采用多塔精馏工艺对冷凝轻烃进行分离,得到液化石油气(LPG)、轻石脑油(C+)和乙烷(CH)等产品。然后,利用Uni Sim Design对整个过程进行模拟,通过灵敏度分析初步确定了膜面积(GPm和RPm)切割比、膜渗透侧压力、精馏塔回流比和塔板数等过程参数适宜值,充分利用分离过程的“双向富集”效应。结果表明,当GPm和RPm的面积分别为3772.6m和600 m时,GPm和RPm的级切割分别为0.51和0.80。最后,利用响应面方法(RSm)对过程参数进行优化。根据所建立的流程模型,首先通过基于(Central Composite Design,CCD)的实验设计方法筛选出对年度总收益(TAP)具有显著性影响的因素:GPm膜面积、RPm膜面积和压缩机K-2的出口压力,然后通过最陡爬坡法确定响应面分析的中心点,最后根据Box-Behnken中心组合实验设计原理,拟合了TAP与三个关键因素的关联方程并进行响应面分析,得出冷凝-膜-PSA-精馏耦合系统的最优操作参数使TAP最大。通过对工艺方案进行经济评估,确定了年度运营费用和总投资,结果表明优化方案的年生产总利润为38.62×10美元,投资回收期小于4个月,氢气和轻烃回收率分别达到96%和99%,氢气生产单耗仅0.227 k Wh·Nm,与国外专利技术相比,能耗减少幅度达27%。
