ZSM-5 Raupapa Hanga-whiriwhiri Zeolites
Ka taea te whakamahi i te ZSM-5 zeolite mo te ahumahi petrochemical, te ahumahi matū pai me etahi atu mara na te mea he motuhake te toru-ahu whiti whiti pore awa, motuhake hanga-whiriwhiri crackability, isomerization me te kaha aromatization. I tenei wa, ka taea te tono ki te whakakorikori FCC, ki nga taapiri ranei ka taea te whakapai ake i te tau octane penehīni, nga whakakorikori hydro/aonhydro dewaxing me te tukanga waeine xylene isomerization, toluene disproportionation me alkylation. Ka taea te whakanui ake i te nama octane penehīni, ka taea hoki te whakanui ake i te ihirangi olefin mena ka whakauruhia nga zeolite ki te whakakorikori FCC i roto i te tauhohenga FBR-FCC. I roto i to taatau kamupene, ko te ZSM-5 raupapa ahua-tiwhiringa zeolite he rereke te rereke o te silica-alumina, mai i te 25 ki te 500. Ka taea te whakarereke i te tohatoha matūriki kia rite ki nga whakaritenga a nga kaihoko. Ko te kaha o te isomerization me te pumau mahi ka taea te whakarereke i te wa e whakatikahia ana te waikawa ma te huri i te ōwehenga silica-alumina kia rite ki o hiahia.

| Te Tukanga Whakakotahitanga: I raro i te pāmahana teitei me nga tikanga pehanga teitei, ka puta nga zeolite ZSM-5 i muri i te whakamaaramatanga o te pūhui waiariki, te tātari, te horoi, te whakarereke me te whakamaroke ma te whakamahi i te tote konumohe me te silicate hei taonga matua. | ||
