Contain the fifth of the ten Heavenly Stem of double-loop of on zeolite activator 4 hydrogen compose of different of 2 Xi catalysis cites the article: Feng Ruming, hu Haojie, ling Fang. On zeolite activator 4 - hydrogenous double-loop the fifth of the ten Heavenly Stem compose of different of 2 Xi catalysis [J] . Chemical reagents, 2023, 45 (4) : 106-112. DOI:10.13822/j.cnki.hxsj.2022.0823 setting introduces King Kong alkyl (ADM) it is the saturated cycloalkanes hydrocarbon that has basket shape structure one kind, performance is steady, can apply at medicine the domain such as activator of intermediate body, epoxy resin, sensitive data, isomerization and modified lube. By annulus the fifth of the ten Heavenly Stem 2 Xi 2 get together body (DCPD) the process cost that compose of hydrogenation, different controls King Kong alkyl is low, accordingly this craft attracted the interest of many researcher in nearly 30 years, especially the isomerization reaction in this craft. Because the Lewis such as 3 chloridize aluminium is acerbity,activator is applying at isomerization, although have tall one-way close rate, but this craft is had strong caustic with alternative low characteristic, because this seeks a kind of activator that replaces 3 chloridize aluminium and technology,become the heat that studies scientificly.

Article window 1 is opposite the Y zeolite at convention, the Y zeolite of little grain shows exceedingly good catalysis active; The zeolite of little grain Y of 2 La modified shows the catalytic performance with went out better and stability, have the sense of further industrialized research. Content introduces 1 experiment part 2 results and the fifth of the ten Heavenly Stem of catalytic reaction annulus that discuss zeolite of 2.1 different structures to go up 2 Xi 2 get together body (DCPD) the TCD that gets after saturated on RaneyNi activator hydrogenation basically is Endo compose isomer, content of Exo compose isomer under 2.5 Wt%[37] . The zeolite that chooses 4 kinds of convention is activator, it is reactant with Endo compose isomer, if the watch is shown 1 times, on ZSM-5(38.0) and MOR(24.6) zeolite, of Endo-TCD change rate it is respectively 6.3% with 10.2% .

If the graph is shown 1 times, the diagnostic diffractive peak that XRD a collection of illustrative plates makes clear to activator of 4 kinds of zeolite has corresponding structure respectively. If the graph is shown 2 times, from the desorption of NH3 the curve can see, 4 kinds of zeolite all have higher acerbity volume, see from NH3 desorption temperature, MOR and ZSM-5 have higher desorption temperature, make clear to stronger acidity is had on these 2 kinds of zeolite.

Graph comparative cadre cent discussed the catalytic active of the NH3-TPD Fig.2 Graph Of NH3-TPD On Different Zeolites 2.2 NaY of zeolite of 2 different structures and HY zeolite the 2 sort with Y common zeolite, the Na function with isomerization of TCD of catalysis of H Y zeolite. Graph the 3 reaction data that compare for different reaction temperature and different NaY and Endo-TCD quality,

Graph 3 temperature and activator / the influence Fig.3 Influence Of Temperature And Mass Ratio Of Catalyst To Endo-TCD of Endo-TCD ratio is shown 4 times like the graph, the Y zeolite after be being exchanged through NH4+ is had taller change rate, below situation of same quality specific value, endo-TCD is changed rate increased 20% , this shows HY zeolite has taller catalytic active, as the addition of activator and Endo-TCD quality specific value, the Endo-TCD on HY zeolite is changed rate increase 80% the left and right sides, zeolite of remarkable prep above NaY.

The Fig.4 Catalytic Performance Of NaY And HY 2.3 Exo-TCD of catalytic performance data of graph 4 NaY and HY has sublimate characteristic as a result of Endo-TCD in the catalytic isomerization on HY zeolite, when reaction temperature exceeds 220 ℃ , the choice is isomerization reactant with Exo-TCD. If the graph is shown 5 times, on HY zeolite, of Exo-TCD change the rate rise as temperature and increase, changing rate increase while, the heavy constituent content in child increases, did not detect in reaction child Endo-TCD compose isomer.

3 conclusion the reaction of 2 Xi catalytic different compose on zeolite makes clear the fifth of the ten Heavenly Stem of 4 hydrogen double-loop, y zeolite relatively ZSM-5, MOR shows taller catalytic active. Relative to the Y zeolite at convention, the Y zeolite of little grain shows exceedingly good catalysis active. Through the stability of activator can increasing after La modified, the loop of activator uses a frequency to increase. The zeolite of little grain Y of La modified shows the catalytic performance with went out better and stability, have the sense of further industrialized research.
