Abstract
向在浊点以下10℃时含有4—10Wt%蜡并基本上不含有大于正三十烷的烷烃的馏分燃料油中添加正构烷烃,提供大于燃料油的0.35Wt%的C24和更高级的烷烃,从而提高其对低温流动改进剂的感受性。
Description
本发明涉及含有流动改进剂的馏分燃料组合物。
含有直链烷烃蜡的取暖用油和其它馏分石油燃料,如柴油,在低温时势必沉淀出大块晶体,这样建立起的凝胶结构导致燃料油丧失其流动性。燃料油仍能流动的最低温度通常称为倾点。
当燃料油温度达到或低于其倾点,燃料油不能再自由地流动时,用管路和泵输送燃料油就会造成困难,例如当试图利用重力或泵压将燃料油从一个储存容器输送到另一个输存容器或试图将燃料油加进燃烧器时就会困难。
在倾点温度以上,溶液中产生的晶体也往往堵塞燃料油管路、筛网和过滤器。这些问题过去便是众所周知,并且有人建议使用各种添加剂以降低燃料油的倾点并减小蜡晶体的大小。这些添加剂的功能之一是改变从燃料油中沉淀的晶体的性质,从而减少蜡晶体形成凝胶的可能性。细小的晶体是理想的,这样沉淀出的蜡将不会堵塞在燃料油的运输、储存和调配设备中使用的细孔筛网。最理想的燃料油不但应具有较低的倾点(流点),而且应形成细小的蜡晶,这样在低的操作温度下过滤器的堵塞将不会减弱燃料油的流动。
向在浊点以下10℃含有直到4Wt%正构烷烃(用重量分析法或差示扫描量热法(DSC)测定)的馏分油中加入主要是乙烯-乙酸乙酯共聚物(EVA)基的流动改进剂可有效的改善蜡晶(用CFPP和其它操作性能试验,以及用模拟和野外使用性能测定)。通常炼油工作者调整馏分油的ASTM D-86蒸馏特性以把尾部90%馏分至终馏点之间的温差增加到20~25℃来促进在这些馏分中添加剂的感受性。
美国专利3020696提出在美国1968年通用的低含蜡量的中间馏分燃料油对按照法国专利1461008制备的乙烯和乙酸乙烯酯共聚物的感受性可以通过掺入少量的石蜡得到改进,石蜡的用量为0.03~2Wt%,石蜡的平均分子量为300~650。同样地,美国专利3040691提出相同类型的中间馏分油对相同的添加剂的感受性可以通过添加烷烃馏分油得到改进,所说的烷烃馏分油含有比正二十六烷更高到正四十烷的烷烃以提供C24和更高级正构烷烃的量为0.1~2Wt%。在这些专利中,添加C24和更高级的蜡最少量为0.1Wt%,最大量为0.3Wt%,都表明改进了感受性。
然而,当处理高含蜡量窄沸程馏分,如那些在远东和澳大利亚所遇到的馏分时,尽管这些馏分具有类似的蒸馏特性,但是有更高的含蜡量(用DSC法或重量分析法测定的在浊点以下10℃时含蜡量为5~10Wt%),并有不同的碳原子数分布,特别是在C22~C28的范围内时,上述那些做法是无效的。特别困难的是处理那些具有高蜡含量并有较低终馏点的燃料油,即终馏点不超过370℃,有时还要低于360℃的燃料油,这些燃料油在窄碳原子数分布范围内具有高含蜡量。最困难的是处理那些从高蜡原油,如从澳大利亚和远东地区的原油中得到的燃料油,这些燃料油用气-液色层分离法测定馏分的正构烷烃总含量可大于20%,全部含C12和更高级的正构烷烃。
最近,日本专利公开说明书615811586提出可通过调节燃料油的总含蜡量在5.5~12Wt%,最好通过调合高和低含蜡量燃料的方法改善中间馏分对流动性改进剂的感受性。含蜡量是在-20℃时用丁酮从一克燃料油中沉淀出的蜡。这项技术对通过添加剂处理的燃料油的含蜡量不是令人满意的,因为其是在燃料油的浊点和被添加剂处理的操作性能点之间沉淀出的蜡,而操作性能点对燃料油的低温特性是重要的。我们发现这些燃料油对流动改进剂的感受性能不取决于燃料油的总含蜡量。
一种典型较难处理的馏分燃料油,其在它的浊点下10℃时含有5~10Wt%的蜡和/或含有20Wt%以上的正构烷烃C12+,其具有如下的ASTM D-86特性:
初馏点 212℃
5% 234℃
10% 243℃
20% 255℃
30% 263℃
40% 279℃
50% 288℃
60% 298℃
70% 303℃
80% 321℃
90% 334℃
95% 343℃
终馏点 361℃
我们发现,与前面介绍的日本专利申请615811586相对照,这样的馏分燃料油对流动改进剂的感受性可通过向燃料油中加入某些物质得到改善,加入的物质在限定含蜡量的范围内加宽含蜡量的碳原子数的分布。
按照本发明的液体燃料油组合物主要含有(按重量计)馏分燃料油,该馏分燃料油在浊点下10℃时含有4~10Wt%的蜡并有较窄的正构烷烃分布,即基本上不含比正三十烷(C30)更高级的烷烃,该液体的燃料组合物并含有(按馏分燃料油计)0.001~2.0Wt%的低温流动改进剂和0.001~2.0Wt%的添加的正构烷烃,所添加的正构烷烃中C24和更高级的烷烃的量大于燃料油重量的0.35Wt%。
另外根据本发明,低温流动改进剂应用于馏分燃料油,该馏分燃料油在浊点下10℃时含蜡4~10Wt%并有较窄的碳原子数分布,即基本上不含比馏分燃料油流动改进剂和添加的正构烷烃的混合物的正三十烷(C30)更高级的烷烃,所添加的正构烷烃C24和更高级烷烃的量大于燃料油重量的0.35Wt%。
本发明中所用的流动改进剂可以是任何一种常用的流动改进剂,然而我们推荐使用含有乙烯和至少一种第二种不饱和单体共聚物型的流动改进剂。该第二种不饱和单体可以是另一种单烯烃,例如C3~C18的α-单烯烃或可以是一种不饱和酯,如乙酸乙烯酯、丁酸乙烯酯、丙酸乙烯酯、异丁酸月桂酯、丙烯酸乙酯或其它类似物。该第二种单体也可以是不饱和单酯或双酯与支链或直链α-单烯烃的混合物。也可以使用共聚物的混合物,例如乙烯和乙酸乙烯酯的共聚物与烷基化的聚苯乙烯或与酰化的聚苯乙烯的混合物。可采用的其它物质有氨基琥珀酸衍生物、酯类如聚丙烯酸酯和酯化的马来酐共聚物、聚α-烯烃等等。
本发明中使用的较佳馏分燃料油流动改进剂是由每摩尔不饱和烃单体含有1~40,较好是1~20,更好是3~20摩尔的乙烯组成,其中不饱和烯单体可以是单一单体或这样的单体以任意比例的混合物,所说的聚合物是油溶的并且其平均分子量约为1000~50000,最好约1000~5000。分子量可以使用冰点降低法或汽相渗透压法测定,例如使用梅克罗贝(Mechrolab)汽相渗透仪310A型测定分子量。
不饱和单体可以均聚或与乙烯或其相互共聚,其包括不饱和酸、酸酐、单酯和二酯,通式如下:
式中R1是氢或甲基;R3是-OOCR4或-COOR4基,其中R4是氢或C1~C16,最好是C1~C4的直链或支链烷基,且R3是氢或-COOR4。当R1与R3是氢且R2是-OOCR4时,单体包括C2~C7一元羧酸的乙烯醇酯。这些酯的例子包括乙酸乙酯、异丁酸乙酯、月桂酸乙酯、肉豆蔻酸乙酯、棕榈酸乙酯等等。当R2是-COOR4时这些酯包括C8羰基合成醇的丙烯酸酯、丙烯酸甲酯、异丁烯酸甲酯、丙烯酸月桂酯、异丁烯酸异丁酯、α-异丁烯酸的棕榈醇酯、异丁烯酸的C13羰基合成醇酯等等。当R1是氢且R2和R3都是-OOCR4时单体的例子包括单C12羰基合成醇的反丁烯二酸酯、马来酸二异丙基酯、反丁烯二酸二月桂基酯、反丁烯二酸乙基甲基酯;富马酸、马来酸等等。当R2是氢、R1是COOR4并且R3是CH2COOR4时,单体为衣康酸酯。
在本发明中,用于制备倾点下降剂或流动改进剂的可与乙烯共聚合的其它不饱和单体包括C3~C16的支链或直链α-单烯烃,例如丙烯、正辛烯-1、2-乙基癸烯-1、正癸烯-1等等。
在共聚物中也可以包括少量(如约0~20摩尔百分数)的第三种单体,甚至第四种单体,例如C2~C16的支链或直链α-单烯烃,如丙烯、正辛烯-1、正癸烯-1等等。因此,3~40摩尔的乙烯与1摩尔的30~99%(摩尔)的不饱和酯和70~1%(摩尔)的烯烃的混合物的共聚物也可以使用。
所形成的这些共聚物是主要由分布有烃或氧取代的烃的侧链的乙烯聚合物主链所组成的无规共聚物。
制备上述酯所用的醇是由烯烃(如C3~C4单烯烃的聚合物和共聚物)制备的支链脂族伯醇的异构混合物,在含钴催化剂(如羰基钴)的存在下烯烃与一氧化碳和氢反应,反应温度为300°F~400°F,反应压力为1000~3000psi,生成醛,然后将得到的醛产物加氢生成醇,醇可用蒸馏方法从加氢产物中回收。
也优先选用那些侧链低度支化的共聚物,特别是那些在每100个甲基中含有少于10个,最好是少于8个甲基终止侧链(酯基除外)的共聚物,其是用核磁共振法测定的,最好用500兆赫芝质子核磁共振分析。
流动改进剂的使用浓度按被处理的馏分燃料油计约为0.001~2Wt%,最好约0.005~0.2Wt%。
第二种添加剂提供大于C24的正构烷烃,且最好是碳原子分布在约20~40的蜡。尽管蜡中也可含有少量的支链烃,但我们还是希望蜡主要由直链烷烃组成。加入的蜡可以是纯蜡或炼厂的物流,如常压重瓦斯油、减压瓦斯油或裂化重瓦斯油,这些炼厂物流含有碳原子数在所需范围内的限定量的蜡。可以认为加入的蜡是在燃料油中正构烷烃结晶的晶核,并且与从燃料油中最先沉淀出来的正构烷烃共结晶。因此,添加的蜡的优选正构烷烃分布取决于特定的燃料。虽然C24和更高级的正构烷烃组分应大于燃料油重量的0.35Wt%,但我们推荐其值应大于燃料油重量的0.5Wt%。
也可以使用其它添加剂进一步改善低温性能,例如肼,最好是二羧酸或酐(如邻苯二甲酸酐)的半酰胺、半胺盐并且可以添加烷基最好是含有12~20个碳原子的仲胺。特别优选的化合物是邻苯二甲酸的半酰胺、半胺盐和二氢脂胺-Armeen 2HT(大约有4Wt%正C14烷基、30Wt%正C16烷基、60Wt%正C18烷基,其余则是不饱和物)。肼、半酰胺、半胺盐的添加量通常是馏分燃料油重量的0.001~2Wt%,最好是0.005~0.2Wt%。
其它添加剂的例子是乙二醇酯,如在我们的EP0061895B中所定义的那些酯;这些酯和马来酸酐的胺的共聚物,如EP公开号0214786中所定义的那些共聚物;聚烯烃和氯化聚烯烃及烷基琥珀酸酐的胺或酰胺。
向馏分燃料油中添加蜡-萘缩合物可进一步改善馏分燃料油的低温流动性。典型的缩合物是通过氯化含有正链和支链的C18~C39(平均为C26)烷烃的蜡,得到含有约15Wt%氯的氯化蜡而制备的。这样得到的氯化蜡经过烷基化反应与萘聚合得到一种可应用的含有交替蜡和萘单元的缩合物。
添加的缩合物的量以馏分燃料油的重量计通常为0.00005~0.1Wt%。
本发明的添加剂常常作为浓缩物合并到主体燃料中,本发明进一步提供一种浓缩物,其包括含有30~70Wt%,最好40~60Wt%的乙烯和其它烯的不饱和单体的共聚物与烃蜡的混合物的溶液。
在实施例中使用下列添加剂:
添加剂1:63Wt%的两种乙烯-乙酸乙烯酯共聚物的混合物的溶液,由埃克森(Exxon)化学公司销售,商品名为ECA8400。
添加剂2:添加剂1加上10Wt%的蜡-萘缩合物。
添加剂3:一种由(1)乙烯-乙酸乙烯酯共聚物(2份重)(2)蜡-萘缩合物和(3)1份重的邻苯二甲酸的半酰胺-半胺盐和二氢化脂胺(Armeen 2HT)所组成的混合物。蜡-萘缩合物的量占共聚物(1)和半酰胺-半胺盐(2)总重量的5Wt%。
添加剂4:按照法国专利1461008制备的45Wt%的分子量约为2000的高支化的乙烯-乙酸乙烯酯共聚物,并且乙酸乙烯酯的含量为30Wt%的溶液。
添加剂5:由埃克森公司销售的商品名为巴拉弗洛(Paraflow)206的乙烯-乙酸乙烯酯共聚物和富马酸-乙酸乙烯酯共聚物的调合物。
添加剂6:一种作为芳烃稀释剂的浓缩物由大约50Wt%的两种乙烯-乙酸乙烯酯共聚物的混合物组成,该共聚物中有约75Wt%的蜡生长阻止剂和大约25Wt%成核剂。蜡生长阻止剂是由乙烯和大约38Wt%乙酸乙烯酯所组成,其数均分子量约为25~35。成核剂是由乙烯和大约16Wt%乙酸乙烯酯所组成,其数均分子量约为3000(VPO)。该共聚物在英国专利1374051中用共聚物H表示。

燃料油通过过滤器的能力用低温过滤堵塞点试验(CFPPT)评价,试验的操作步骤在《英国石油学会志》卷52,No.510,1966年6月第173~185页中有详细说明。简单地说,就是将40毫升要试验的油样放入维持在约-34℃的冷浴中冷却,定时地(由不低于浊点以上5℃开始每降低1℃)试验冷却的油,测其在一定的时间内流过细孔筛网的能力。试验低温性质用的设备由一个移液管组成,其较低一端与一个位于试验油液面下方的倒置漏斗相连。漏斗的扩大的口是一个面积约0.45平方英寸的350目筛子。定期试验是在每次开始时将移液管的上端抽真空,从而将油通过筛子抽上来进入移液管,直到标有20毫升油的标记处。温度每降低1℃重复一次试验,直到油不足以注满移液管中20毫升油的标记处为止。
温度每降低1℃重复试验一次,直到油在60秒内不能注满移液管为止。记录最后一次开始过滤时的温度,并记做低温过滤堵塞点。
