相关申请的交叉引用
本申请要求2015年7月2日提交的美国临时申请序列号 62/188,178的权益。
技术领域
本公开的实施方案大体上涉及经由复分解反应进行的丙烯生产,并且更确切地说,涉及使用包含复分解催化剂和裂化催化剂的双重催化剂体系将丁烯转化成丙烯。
背景技术
近年来,对丙烯的需求已经显著增加以满足聚丙烯、环氧丙烷以及丙烯酸的不断增长的市场。目前,世界范围内生产的大部分丙烯(7400万吨/年)是来自主要生产乙烯的蒸汽裂化单元的副产物(57%)、或来自主要生产汽油的流体催化裂化(FCC)单元的副产物(30%)。这些过程不能充分应对丙烯需求的快速增长。
其它丙烯生产工艺占总丙烯产量的约12%。在这些工艺中有丙烷脱氢(PDH)、需要乙烯和丁烯这两者的复分解反应、高苛刻度FCC、烯烃裂化以及甲醇制烯烃(MTO)。然而,丙烯需求已经超过乙烯和汽油/馏分油需求,并且丙烯的供应并没有跟上丙烯需求的这一增长。
发明内容
因此,对使用双重催化剂体系选择性生产丙烯的改进的方法存在持续的需求。本公开的实施方案涉及经由双重催化剂体系从丁烯生产丙烯。
在一个实施方案中,提供了一种用于生产丙烯的方法。所述方法包括提供包含以下各项的双重催化剂体系:浸渍有金属氧化物的介孔二氧化硅催化剂、以及所述介孔二氧化硅催化剂下游的丝光沸石骨架反转(MFI) 结构化的二氧化硅催化剂。所述介孔二氧化硅催化剂包括至少约0.600cm3/g 的总孔体积,并且所述MFI结构化的二氧化硅催化剂包括0.001mmol/g至 0.1mmol/g的总酸度。所述方法还包括通过使包含丁烯的物流与所述双重催化剂体系接触来经由复分解和裂化从所述包含丁烯的物流生产丙烯,其中所述包含丁烯的物流先接触所述介孔二氧化硅催化剂,之后接触所述MFI结构化的二氧化硅催化剂。
在另一个实施方案中,提供了一种用于从丁烯生产丙烯的双重催化剂体系。所述双重催化剂体系包含复分解催化剂区和所述复分解催化剂区下游的裂化催化剂区。所述复分解催化剂区包含浸渍有金属氧化物的介孔二氧化硅催化剂,其中所述介孔二氧化硅催化剂包括至少2.5nm至40nm的孔径分布和至少0.600cm3/g的总孔体积。所述裂化催化剂区包含丝光沸石骨架反转(MFI)结构化的二氧化硅催化剂,其中所述MFI结构化的二氧化硅催化剂包括至少1.5nm至3nm的孔径分布、和0.001mmol/g至0.1mmol/g的总酸度。
所述的实施方案的另外的特征和优势将在随后的详细说明中阐述,并且部分地对于本领域技术人员来说将从该说明中显而易见或将通过实施所述的实施方案来识别,包括随后的详细说明、权利要求书、以及附图。
附图说明

具体实施方式
本公开的实施方案涉及用于经由催化复分解和催化裂化将包含丁烯的物流转化成包含丙烯的物流的体系和方法。确切地说,本发明的实施方案涉及一种用于从丁烯流更大程度生产丙烯(C3=)的含有复分解催化剂和裂化催化剂的两阶段催化剂体系。在操作中,复分解催化剂之后是裂化催化剂以提供更大的丙烯产率、以及任选的更大的丙烯和乙烯的组合产率。
如下式1和2中所示,“复分解”或“自复分解”一般是两步过程:使用复分解催化剂体系的2-丁烯异构化,然后是交叉复分解。如下式3中所示,“催化裂化”指的是将C4-C6烯烃转化成丙烯和其它烷烃和/或烯烃,例如 C1-C2烯烃。
式1:2-丁烯异构化
式2:交叉复分解
式3:催化裂化
参考式1-式3,“复分解”反应和“催化裂化”反应不限于这些反应物和产物;然而,式1-式3提供了反应方法的基本说明。如式1和式2中所示,复分解反应在两个烯烃之间发生。与双键的碳原子键合的基团在分子之间交换以产生具有交换基团的两个新的烯烃。被选用于烯烃复分解反应的特定催化剂一般可以决定是形成顺式异构体还是反式异构体,这是因为烯烃分子与催化剂的配位起重要作用,取代基对新形成的分子的双键的空间影响也是如此。
本发明的双重催化剂体系包含:介孔二氧化硅催化剂,所述介孔二氧化硅催化剂是浸渍有金属氧化物的介孔二氧化硅催化剂载体;以及所述介孔二氧化硅催化剂下游的丝光沸石骨架反转(MFI)结构化的二氧化硅催化剂。各种结构被考虑用于所述介孔二氧化硅催化剂载体,例如分子筛。如本申请中所用的“介孔”意指二氧化硅载体具有窄的孔径分布。确切地说,所述介孔二氧化硅催化剂包括约2.5nm至约40nm的窄的孔径分布和至少约0.600cm3/g的总孔体积。不受理论所束缚,本发明的孔径分布和孔体积被尺寸设定成实现更好的催化活性和减少的孔被金属氧化物堵塞,而更小的孔体积和孔径催化剂体系容易发生孔堵塞,从而使得催化活性降低。
此外,利用所述介孔二氧化硅催化剂下游的MFI结构化的二氧化硅催化剂惊人地提供了从丁烯流生产丙烯的最好产率。本领域普通技术人员本来是通过首先将丁烯裂化成丙烯,然后经由复分解将任何剩余的丁烯裂化来预期最好的产率。然而,惊人地发现,通过将MFI结构化的二氧化硅催化剂放置在介孔二氧化硅催化剂的下游,丙烯产率增加,并且除此之外,丙烯和乙烯的组合产率增加。
在一个或多个实施方案中,所述介孔二氧化硅催化剂的孔径分布可以在以下范围内:约2.5nm至约40nm、或约2.5nm至约20nm、或约2.5 nm至约4.5nm、或约2.5nm至约3.5nm、或约8nm至约18nm、或约12 nm至约18nm。在另外的实施方案中,所述总孔体积可以是约0.600cm3/g至约2.5cm3/g、或约0.600cm3/g至约1.5cm3/g、或约0.600cm3/g至约1.3 cm3/g、或约0.600cm3/g至约0.800cm3/g、或约0.600cm3/g至约0.700 cm3/g、或约0.900cm3/g至约1.3cm3/g。
此外,虽然考虑了更宽的范围,但是在一个或多个实施方案中,所述介孔二氧化硅催化剂可以包括约250平方米/克(m2/g)至约600m2/g的表面积。在另外的实施方案中,所述介孔二氧化硅催化剂可以具有以下表面积:约450m2/g至约600m2/g、或约250m2/g至约350m2/g、或约275m2/g 至约325m2/g、或约275m2/g至约300m2/g。此外,所述介孔二氧化硅催化剂可以具有以下总酸度:最多约0.5毫摩尔/克(mmol/g)、或约0.01mmol/g 至约0.5mmol/g、或约0.1mmol/g至约0.5mmol/g、或约0.3mmol/g至约0.5 mmol/g、或约0.4mmol/g至约0.5mmol/g。酸度一般维持在约0.5mmol/g或小于约0.5mmol/g以获得所期望的丙烯选择性和减少的不期望的副产物,如芳族化合物的产生。增加酸度可以提高总丁烯转化率;然而,该提高的转化率可能会导致更小的选择性和芳族副产物的产生增加,这可能会导致催化剂结焦和失活。
此外,所述介孔二氧化硅催化剂可以具有以下粒度:约20nm至约200nm、或约50nm至约150nm、或约75nm至约125nm。在另外的实施方案中,所述介孔二氧化硅催化剂可以具有以下单个晶体尺寸:约1μm至约100μm、或约10μm至约40μm。
考虑了介孔二氧化硅载体的各种制剂以及制备所述制剂的方法。举例来说,所述介孔二氧化硅催化剂载体可以经由湿式浸渍、水热合成、或这两者来制备。此外,所述介孔二氧化硅催化剂载体的特征可以在于有序孔结构。举例来说,该有序结构可以具有孔的六角形阵列。具有六角形孔阵列的介孔二氧化硅载体的一个合适的实施方案可以是圣芭芭拉无定形(Santa Barbara Amorphous)(SBA-15)介孔二氧化硅分子筛。或者,介孔二氧化硅载体的另一个合适的实施方案是由富士硅化学株式会社(Fuji Silysia Chemical Ltd.)生产的CARiACT Q-10(Q-10)球形催化剂载体。
复分解反应的催化剂是二氧化硅载体的浸渍的金属氧化物。所述金属氧化物可以包含来自IUPAC元素周期表(IUPAC Periodic Table)的第6 族-第10族的金属的一种或氧化物。在一个或多个实施方案中,所述金属氧化物可以是钼、铼、钨、或其组合的氧化物。在一个具体的实施方案中,所述金属氧化物是氧化钨(WO3)。预期可以将各种量的金属氧化物浸渍到介孔二氧化硅催化剂载体中。举例来说而不是以限制的方式,二氧化硅与金属氧化物(例如WO3)的摩尔比是约5至约60、或约5至约15、或约20至约 50、或约20至约40、或约25至约35。
此外,各种二氧化硅结构被考虑用于MFI结构化的二氧化硅催化剂。举例来说,所述MFI结构化的二氧化硅催化剂可以包括MFI结构化的铝硅酸盐沸石催化剂或不含氧化铝的MFI结构化的二氧化硅催化剂。如本文所用的“不含”意指在MFI结构化的二氧化硅催化剂中的氧化铝少于0.001重量%。此外,预期除了氧化铝之外或作为氧化铝的替代物,MFI结构化的二氧化硅催化剂可以包括其它浸渍的金属氧化物。类似于介孔二氧化硅催化剂,所述MFI结构化的催化剂可以具有浸渍在二氧化硅载体中的氧化铝、金属氧化物、或这两者。除了氧化铝之外或作为氧化铝的替代物,预期包括先前所列的金属氧化物,特别是来自IUPAC元素周期表的第6族-第10族的金属的一种或多种氧化物,更特别是钼、铼、钨、钛、或其组合的金属氧化物。
对于MFI结构化的铝硅酸盐沸石催化剂,考虑了各种量的氧化铝。在一个或多个实施方案中,所述MFI结构化的铝硅酸盐沸石催化剂可以具有以下二氧化硅与氧化铝的摩尔比:约5至约5000、或约100至约4000、或约200至约3000、或约1500至约2500、或约1000至约2000。考虑了 MFI结构化的铝硅酸盐沸石催化剂的各种合适的商业实施方案,例如ZSM-5沸石,如由Zeolyst国际公司(Zeolyst International)生产的MFI-280或由沙特阿拉伯国家石油公司(Saudi Aramco)生产的MFI-2000。
各种合适的商业实施方案也被考虑用于所述不含氧化铝的MFI结构化的催化剂。一个这样的实例是由沙特阿拉伯国家石油公司生产的硅沸石- 1(Silicalite-1)。
所述MFI结构化的二氧化硅催化剂可以包括约1.5nm至3nm、或约1.5nm至2.5nm的孔径分布。此外,所述MFI结构化的二氧化硅催化剂可以具有约300m2/g至约425m2/g、或约340m2/g至约410m2/g的表面积。此外,所述MFI结构化的二氧化硅催化剂可以具有约0.001mmol/g至约 0.1mmol/g、或约0.01mmol/g至约0.08mmol/g的总酸度。所述酸度维持在约0.1mmol/g或小于约0.1mmol/g以减少不期望的副产物,如芳族化合物的产生。增加酸度可以提高裂化的量;然而,该提高的裂化也可能会导致更小的选择性和芳族副产物的产生增加,这可能会导致催化剂结焦和失活。
在一些情况下,MFI结构化的二氧化硅催化剂可以用酸度调节剂改性以调节所述MFI结构化的二氧化硅催化剂中的酸度水平。举例来说,这些酸度调节剂可以包括稀土调节剂、磷调节剂、钾调节剂、或其组合。然而,由于本发明的实施方案集中在将酸度降低到等于或低于0.1mmol/g的水平,因此本发明的结构化的二氧化硅催化剂可以不含酸度调节剂,如选自稀土调节剂、磷调节剂、钾调节剂、或其组合的那些。如本文所用的“不含酸度调节剂”意指在所述MFI结构化的二氧化硅催化剂中的酸度调节剂少于0.001 重量%。
此外,所述MFI结构化的二氧化硅催化剂可以具有约0.1cm3/g 至约0.3cm3/g、或约0.15cm3/g至约0.25cm3/g的孔体积。此外,所述MFI 结构化的二氧化硅催化剂可以具有以下范围内的单个晶体尺寸:约10nm至约40μm、或约15μm至约40μm、或约20μm至约30μm。在另一个实施方案中,所述MFI结构化的二氧化硅催化剂可以具有约1μm至约5μm范围内的单个晶体尺寸。
此外,各种量的每一种催化剂被考虑用于本发明的双重催化剂体系。举例来说,预期复分解催化剂与裂化催化剂的体积比可以在约5:1至约 1:5、或约2:1至约1:2、或约1:1的范围内。
在操作中,通过使丁烯流与所述双重催化剂体系接触来经由复分解转化由含有丁烯的物流产生包含丙烯的产物流。所述丁烯流可以包含2-丁烯,并且任选地包含一种或多种异构体,如1-丁烯、反式-2-丁烯、以及顺式- 2-丁烯。本发明的论述集中在基于丁烯的进料流;然而,已知的是,其它C1- C6组分也可能存在于进料流中。
所述介孔二氧化硅催化剂是一种复分解催化剂,它有助于2-丁烯异构化成1-丁烯,继而2-丁烯和1-丁烯进行交叉复分解,形成包含丙烯和其它烯烃/烷烃,如戊烯的复分解产物流。所述MFI结构化的二氧化硅催化剂位于所述复分解催化剂的下游,它是一种裂化催化剂,所述裂化催化剂从所述复分解产物流中的C4烯烃或C5烯烃产生丙烯,并且还可能产生乙烯。
预期所述复分解催化剂和所述裂化催化剂被设置在一个反应器或多个反应器中。举例来说,当所述复分解催化剂和所述裂化催化剂在不同的环境条件(包括温度和压力)下操作时,可能期望对于它们使用单独的反应器。不管是一个反应器还是多个反应器容纳所述双重催化剂,所述双重催化剂体系将具有复分解催化剂区或区段和下游的裂化催化剂区或区段。举例来说,假定反应物流进入反应器的顶部部分,所述介孔二氧化硅复分解催化剂可以位于所述反应器的顶部部分中,并且所述MFI结构化的二氧化硅裂化催化剂可以被设置在所述反应器的底部部分中。举例来说,每一种催化剂可以被定位为离散的催化剂床。此外,预期所述双重催化剂体系的两种催化剂可以彼此接触或分开。然而,如果复分解催化剂和裂化催化剂接触,那么期望所述复分解催化剂仍被设置在所述裂化催化剂的上游。可以将所述催化剂在同一个反应器中使用或使用串联布置的不同反应器使用。或者,预期所述复分解催化剂(介孔二氧化硅催化剂)被设置在第一反应器中并且所述裂化催化剂(MFI结构化的二氧化硅催化剂)被设置在所述第一反应器下游的单独的第二反应器中。在具体的实施方案中,在第一反应器与第二反应器之间存在直接的管道,以使得裂化催化剂可以直接将丁烯复分解反应的产物裂化。考虑了包括所述催化剂体系的各种系统。关于有关这样的系统的细节,名称为《生产丙烯的系统和方法(Systems and Methods of ProducingPropylene)》的共同未决的沙特阿拉伯国家石油公司的美国申请号62/188,052以引用的方式整体并入本文。
考虑了制备用于所述双重催化剂体系中的催化剂的各种方法。确切地说,可以利用湿式浸渍和水热合成的工艺;然而,也考虑了其它催化剂合成技术。
各种操作条件被考虑用于使丁烯流与所述双重催化剂体系接触。举例来说,所述丁烯流可以按约10h-1至约10,000h-1、或约300h-1至约1200 h-1的时空速度接触所述双重催化剂体系。此外,所述丁烯流可以在约200℃至约600℃、或约300℃至约600℃的温度下接触所述催化剂体系。此外,所述丁烯流可以在约1巴至约30巴、或约1巴至约10巴的压力下接触所述催化剂体系。
任选地,在复分解和/或裂化之前可以将所述双重催化剂体系预处理。举例来说,可以在复分解之前在至少约400℃、或至少约500℃的温度下用N2将所述双重催化剂体系预处理约1小时至约5小时。
由所述双重催化剂体系产生的产物流可以具有至少80摩尔%的丁烯转化率和以摩尔%计至少40%的丙烯产率。在另一个实施方案中,所述产物流可以具有至少85摩尔%的丁烯转化率和以摩尔%计至少45%的丙烯产率。此外,所述产物流可以具有至少15摩尔%的乙烯产率、或至少20摩尔%的乙烯产率。在又另一个实施方案中,所述产物流可以具有至少45摩尔%的丙烯产率、或至少约50摩尔%的丙烯产率。
此外,所述产物流可以包含少于约1重量%的芳族化合物、或少于约5重量%的烷烃和芳族化合物。不受理论所束缚,在一些实施方案中,可能期望芳族化合物和烷烃的产率是低的,这是因为它表示焦炭形成,这可能会导致催化剂失活。
实施例
以下实施例显示了组合用于本发明的双重催化剂中的各种催化剂的制备。
实施例1:制备W-SBA-15(30)
使用钨酸钠作为钨离子源以用于通过直接水热法合成W-SBA- 15。在W-SBA-15的典型合成中,根据Si/W的摩尔比,将钨并入介孔载体 SBA-15的骨架中。将123(P123)溶解在HCl中并且在剧烈搅拌下添加原硅酸四乙酯(TEOS)。然后,将计算量的钨酸钠溶液添加到所述溶液中并且在水热条件下在95℃搅拌3天。将所得的固体过滤,干燥并且在550℃煅烧5小时。以这种方式获得的催化剂被鉴定为W-SBA-15(30),其中30表示硅与钨的摩尔比(Si/W)。凝胶组合物的摩尔比是1SiO2:0.3-0.6 WO3:0.0167P123:5.82HCl:190H2O。
实施例2:制备硅沸石-1
在典型的合成中,将4.26克(g)的四丙基溴化铵(TPA)和 0.7407g的氟化铵溶解在72ml的水中并且充分搅拌15分钟。然后,添加12 g的煅制二氧化硅并且充分搅拌直到匀化为止。将所获得的凝胶高压消毒并且在200℃保持2天。凝胶的摩尔组成是1SiO2:0.08(TPA)Br:0.10NH4F:20 H2O。将所获得的固体产物用水洗涤并且在80℃干燥过夜。通过在空气中在750℃煅烧5小时来去除模板。
实施例3:制备MFI-2000
在典型的合成中,将4.26g的TPA和0.7407g的氟化铵溶解在 72ml的水中并且充分搅拌15分钟。添加12g的煅制二氧化硅并且充分搅拌直到匀化为止。添加适量的硫酸铝并且将所获得的凝胶高压消毒并且在 200℃保持2天。凝胶的摩尔组成是1SiO2:0.0005Al2O3:0.08(TPA)Br:0.10 NH4F:20H2O。将所获得的固体产物用水洗涤并且在80℃干燥过夜。通过在空气中在550℃煅烧5小时来去除模板。
实施例4:制备10WO3/Q10
通过湿式浸渍法制备10WO3/CARiACT Q10。将偏钨酸铵 [(NH4)6H2W12O40·xH2O]的水溶液和商业二氧化硅载体混合在一起并且在烘箱中在110℃干燥12小时并且在550℃煅烧8小时。如下表1中所示,当与母体Q10材料相比时,负载型氧化钨催化剂(10WO3/Q10)具有更低的表面积,这表明在所述载体上氧化钨的存在。
CARiACT Q10载体和10WO3/Q10催化剂的SEM图像分别示于图 1和图2中。CARiACTQ10载体和负载钨的10WO3/Q10这两者均具有75 nm-125nm范围内的粒度。在10WO3/Q10中没有氧化钨颗粒的附聚表明在所述载体上氧化钨的高分散性。参考图2,MFI-2000的SEM图像显示均匀的粒度分布,晶体尺寸是约35μm-50μm。晶体的X轴、Y轴、以及Z轴分别是50μm、16μm、以及3μm。
Q10材料、10WO3/Q10材料以及MFI-2000材料的XRD图谱示于图3-图5中。参考图4,Q10载体在15°-20°处显示出宽峰,这表明所述材料中无定形二氧化硅的存在。进一步参考图4,10WO3/Q10催化剂在23.09、 23.57、24.33以及34.01处显示出峰,这对应于WO3的结晶相。这表明所述催化剂中WO3物质的存在。如图5中所示,MFI-2000的XRD图谱在8°-9°和22°-25°范围内表现出MFI结构的特征峰。在2θ=8.8°处的峰的强度与在22°- 25°范围内的峰是相当的,这表明沸石晶体沿b轴的形成。
实施例5:催化剂特性
表1包括在实施例1-实施例4中所制备的催化剂加上MFI 280的机械特性,所述MFI280是类似于如实施例3中所公开的MFI-2000来制备的。
表1
实施例6:W-SBA-15和裂化催化剂的催化剂性能
测试来自实施例1-实施例4的所制备的催化剂在固定床连续流动反应器(ID:0.25英寸,Autoclave Engineers有限公司)中在大气压下对丁烯复分解反应的活性和选择性。将固定量的催化剂样品(每一种催化剂类型1 ml,总共2ml)填充到反应器管中,在所述反应器的顶部和底部上具有碳化硅。将所述催化剂在N2下在550℃预处理1小时。所有反应均是在550℃的温度、900h-1的GHSV(气体时空速度)、以及大气压下,使用2-丁烯(5 毫升/分钟(ml/min))作为进料,使用氮气作为稀释剂(25ml/min)来进行的。使用配备有GasPro多孔层开口管柱的具有火焰离子化检测器(FID)的 Varian气相色谱仪(Varian 450-GC)在线进行反应产物的定量分析。
表2表明了裂化催化剂MFI-280和MFI-2000单独和以与催化剂 W-SBA-15(30)的组合(双重)模式在2-丁烯的复分解和裂化反应(反应温度:550℃;大气压;900h-1的GHSV)中的催化性能。可以看出的是, W-SBA-15复分解催化剂与下游的MFI-2000裂化催化剂的组合提供了最高的丙烯产率。
表2
表3显示了单独的催化剂W-SBA-15(30)和双重W-SBA-15 (30)/硅沸石-1催化剂在2-丁烯的复分解和裂化反应(反应温度:550℃;大气压;900hr-1的GHSV)中的催化性能。

实施例7:CARiACT Q10和裂化催化剂的催化剂性能
还评价了如实施例4中所述的CARiACT Q10复分解催化剂的催化剂性能。在固定床管式反应器(316级不锈钢管,具有0.312英寸的ID、 0.562英寸的OD以及8英寸的长度)中进行2-丁烯(反式-2-丁烯和顺式-2- 丁烯的1:1混合物)的催化反应。在所述实验中,向反应器中加入2ml的催化剂(单床),所述催化剂先前被筛分到0.5mm-1.0mm直径的粒度。首先将催化剂样品在氮气流中在550℃活化1小时。在反应期间,将进料(2-丁烯)和N2的流速分别维持在5.0ml/min和25ml/min。所述反应是在550℃的温度下在大气压下以900h-1的GHSV(气体时空速度)和5小时的运行时间 (TOS)进行的。在双重催化剂体系的情况下,使用以玻璃棉分开的1ml的每一种催化剂。
在单一催化剂体系和双重催化剂体系这两者中测试负载型氧化钨催化剂并且结果示于表4中。对于双重催化剂体系获得最高的丙烯选择性,其中10WO3/Q10处在反应器的顶部(T)处并且MFI-2000处在反应器的底部 (B)处。当在单床催化剂体系中使用10WO3/Q10复分解催化剂时,获得 31.97摩尔%的丙烯(C3=)产率和12.70摩尔%的戊烯(C5=)产率。这些结果表明在丁烯的复分解期间形成的戊烯没有完全被裂化成丙烯和乙烯。然而,10WO3/Q10(T)/MFI-2000(B)产生3.37摩尔%的戊烯,从而表明在复分解反应期间形成的大部分的戊烯被裂化成丙烯和乙烯。因此,使用在催化剂床的底部处使用裂化催化剂的双重催化剂体系具有明显的优势。此外,当比较10WO3/Q10(T)/MFI-2000(B)与裂化催化剂处在复分解催化剂的上游的相反排列时,与MFI-2000(T)/10WO3/Q10(B)相比,10WO3/Q10 (T)/MFI-2000(B)使得丙烯增加约4.5摩尔%,而仅产生略微更少(约 1.5摩尔%)的乙烯(C2=)。因此,通过使用在催化剂床的底部处使用裂化催化剂的双重催化剂体系明显地使丙烯产率达到最大。
表4
计算方法
使用AUTOSORB-1(康塔公司(Quanta Chrome))在77K通过氮吸附测量样品的表面积。在吸附测量之前,在氮气流下将样品(约0.1g) 在220℃加热2小时。在液氮温度(77K)下测量催化剂的氮吸附等温线。分别通过布鲁诺尔-埃米特-特勒(Brunauer Emmett-Teller,BET)法和巴雷特 -乔伊纳-汉伦达(Barrett-Joyner-Halenda,BJH)法计算表面积和孔径分布。从在P/P0=0.99下吸附的N2量估算总孔体积。Barret EP,Joyner LJ,Halenda PH,J.Am.Chem.Soc.73(1951)373-380。
