Light olefins (C2-C4 olefins) are the most important basic carbon-based building blocks, which are mainly produced from the catalytic cracking of naphtha [1-3].With the rapid depletion of oil reserves and the growing demand for lower olefins, there is an urgent need to develop an alternative technique for producing them from non-petroleum resources such as coal, natural gas, or biomass.Currently, coal has been successfully transformed to olefins in China via the combination of the processes of coal-to-syngas, syngas-to-methanol and methanol-to-olefins [4-6].In order to further improve efficiency and reduce investment, the direct conversion of syngas to olefins has received extensive attention in recent years [7].

针对克劳斯工业催化剂的效率问题,采用计算流体力学理论构建了不同几何结构和尺寸的克劳斯催化剂模型,通过多物理场耦合求解研究了反应温度、克劳斯反应本征速率、催化剂尺寸、孔隙率、孔径以及几何结构对其催化效率的影响。结果表明,催化剂颗粒的直径、孔径和特征尺寸是影响克劳斯工业催化剂有效因子的显著因素。减小催化剂颗粒直径,增大颗粒孔径,特别是增加大孔的直径和比例,能够显著提高催化剂有效因子。通过异形化设计增大催化剂颗粒的外表面积,即减小催化剂颗粒的特征尺寸,是提高克劳斯工业催化剂催化效率的有效途径。

为降低天然气液化中丙烷预冷混合冷剂液化工艺(C3/MRC)的能耗,采用Aspen HYSYS软件建立了优化计算模型。结合KBO法和优化器中的Box算法,以系统最小能耗为目标函数,换热器最小换热温差3℃为约束条件,工艺参数和制冷剂配比为决策变量,对C3/MRC流程进行了优化模拟。结果显示,优化后单位质量天然气的液化能耗为351.49 kW·h/t,与国外经典的C3/MRC液化流程相比,能耗显著降低。
