Abstract
Description
本発明は一般に、芳香族化触媒を用いる炭化水素の芳香族化に関する。特に、本発明は酸素供給物質、窒素供給物質、またはその両方の添加によって芳香族化触媒を活性化および/または強化する方法に関する。
一態様において、本発明は炭化水素流に窒素供給物質、酸素供給物質またはその両方を添加し、強化された炭化水素流を生成させ、この強化された炭化水素流を芳香族化触媒と接触させることを含み、これにより芳香族炭化水素を含有する芳香族化反応塔流出液を生成させる。この場合、触媒は非酸性ゼオライト支持体、第VIII族金属および1種または2種以上のハロゲン化物を含む。
炭化水素の芳香族化にかかわる新規方法およびシステムおよび/または芳香族化触媒の活性化、保護、および/または生産性の増強にかかわる新規方法およびシステムが本明細書に記載されている。一般に、水および水に変換可能な夾雑物は白金の焼結により触媒を損傷させることから芳香族化触媒にとって有害であると考えられていた。したがって、通常、水、酸素供給物質、または窒素供給物質は芳香族化システムから厳格に排除されるべきものと考えられていた。例えば、本明細書に記載の触媒を使用する場合、芳香族化システムおよび/または芳香族化システム内の炭化水素供給材料および/または水素再循環流中の水および酸素の存在は実質的に減少させるか、または排除することが有利であると考えられていた。特に、供給材料および水素再循環中の水レベルは百万容量あたり半部(0.5ppmv)程度に低いことが望まれていた。このような一般的に受け入れられていた知見は供給材料流中における水処理剤および乾燥剤の存在および慣用の芳香族化プロセスの水素再循環流中における乾燥剤の存在によって証明される。このような通常受け入れられていた知見に反して、本発明者等は若干の水分が或る種の芳香族化触媒の活性化、保護、および/または生産性向上に有益であることを見出した。特に、酸素供給物質、窒素供給物質またはその混合物は種々の時点、種々の場所および種々の手段で芳香族化システムに挿入することができ、これにより芳香族化プロセス期間中、1個または2個以上の芳香族化反応塔に特定量の水および/またはアンモニアを存在させることができる。一態様において、芳香族化反応塔内における特定量の水および/またはアンモニアの存在は、芳香族化触媒を活性化するか、または強化する。
M2/n・Al2O3・SiO2・yH2O
式中、「M」は少なくとも1個の交換可能なカチオン、例えばバリウム、カルシウム、セリウム、リチウム、マグネシウム、カリウム、ナトリウム、ストロンチウム、およびアエン、ならびにL−型ゼオライトの基本結晶構造に実質的な変化をもたらすことなく、別種の交換可能なカチオンにより置き換えることができるヒドロニウムイオンおよびアンモニウムイオンのような非金属カチオンを表す。この式において、「n」は「M」の原子価を表し、「x」は2またはそれ以上であり、および「y」はチャンネル中に、またはゼオライトと相互連絡している空隙中に含有されている水分子の数である。
酸素供給物質および/または窒素供給物質を用いる芳香族化触媒の活性化および強化方法およびプロセスパラメータを監視することによるそれらの量の制御方法が開示されており、下記の例は、開示されている方法の特定の態様として、およびその実施および利点を証明するために示すものである。下記例において、水または酸素は、例中に別段の記載がないかぎり、図1および本明細書に示されているような第一反応塔に先立ち、芳香族化供給材料中に注入した。これらの例は説明のために示されているものであって、いかなる様相でも明細書および特許請求の範囲を制限しようとするものではないものと理解する。
