Me pehea te whakamahi i te tatari molecular 4A?He aha nga whakaritenga mo te taiao e whakahaere ana?Ka rite ki te rauemi maiengi, 4A te tatari rāpoi te whakamahia whānuitia i roto i te maha mara no te mea o tona tatari rāpoi microporous rite rauemi wehenga adsorption, rauemi whakawhiti katote me rauemi catalytic.
Tuatahi, me titiro ki te whakaurunga o te tatari mole 4A:
Na te mea he 0.4nm te rahi o te pore whai hua, ka kiia ko te 4A molecular sieve, ka taea te whakauru i nga puhui ngota iti penei i te wai, methanol, ethanol, carbon dioxide, ethylene, sulfur dioxide, hydrogen sulfide, me te propylene.
- 1. Rahi rāpoi o te tikanga whakamahi 4A rapoi tatari
Na te mea he 0.4mm te rahi o te pore whai hua, kaore e taea e ia te whakauru i tetahi ngota ngota (tae atu ki te propane) me te diameter nui atu i te 0.4mm, engari ko tana mahi whakaurunga whiriwhiri mo te wai he teitei ake i etahi atu ngota, a ko tetahi o nga momo ngota i whakamahia nuitia. momo tatari i roto i te ahumahi.
- Ko te taiao whakahaere o te tikanga whakamahi o te tatari molecular 4A
1. Ka 110°C te pāmahana, ka taea te whakaeto i te wai i roto i te waahi nui, engari kaore e peia atu te wai i roto i nga pores o te tatari ngota.Na reira, i roto i te taiwhanga, ka taea te whakahohe me te whakamakuku ma te whakamaroke i roto i te oumu muffle.Ko te pāmahana he 350°C, ka whakamarokehia i raro i te pehanga noa mo te 8 haora (mehemea he papu korehau, ka taea te whakamaroke i te 150°C mo te 5 haora).
2. Ko te tatari molecular 4A kua whakahohehia ka whakamataohia ki te 200°C (mo te 2 meneti) i te rangi, me pupuri tonu ki roto i te desiccator.
3. I roto i te taiao e whakaaetia ana, me tono te whakamarumaru hauota maroke i te wa e whakamahana ana me te tiaki, ka taea te aukati i te kohu wai o te rangi kia kore e uru mai ano.No te mea ko te tatari ngota tawhito i muri i te whakamahinga he mea poke, kaua e whakakorikoria anake i te mahana o te 450°C, engari me whakauru ano te kohu wai, te hau inert ranei (hauota, me etahi atu) hei whakakapi i etahi atu matū i roto i te tatari ngota.
4. A ape i te hinu me te wai wai i te wa e whakamahi ana, ka ngana ki te karo i te whakapiri tika ki te hinu me te wai wai.
Ka rite ki te aluminosilicate whakarewa alkali, 4A tatari rāpoi e paingia ana e te maha o nga kaihoko i te whakamaroke o te hau me te wai, ka taea hoki te whakamahi mo te para me te purenga o te hau, te wai ranei, penei i te tangohanga o te argon.Na, kei te mohio koe ki nga whakatupato mo tana whakamahinga?
