Hoʻokō Adsorption o 4A Molecular Sieve no H₂S

Pehea e pili ana i ka hana adsorption o 4A molecular sieve no H₂S?I mea e hoʻoponopono ai i ka pilikia o ka H₂S pollution pollution i loko o ka landfills, Ua koho mākou i nā kumu kūʻai haʻahaʻa maka lanahu gangue a me kaolin i koho ʻia, hana ʻia ʻo 4A molecular sieve me ka adsorption maikaʻi a me ka hopena catalytic ma o ke ʻano hydrothermal.Ua aʻo nui ka hoʻokolohua i ka hopena o ka mahana calcination like ʻole a me ka manawa crystallization ma ka hana adsorption desulfurization.

Hōʻike nā hopena i ka hana ʻana o ka adsorption desulfurization o 4A molecular sieve i hoʻomākaukau ʻia e kaolin i ʻoi aku ka maikaʻi ma mua o ko ka lanahu gangue.ʻO ka mahana calcination he 900 ℃, ka mahana crystallization he 100 ℃, ka manawa crystallization he 7h, a ʻo ka ratio o ka mea i ka wai he 1:7.Ke 3mol / L ka nui o ka alkali, hiki i ka desulfurization ke hiki i 95mg / g.X-ray diffraction kālailai hōʻike 'ana i maopopo elemental sulfur hiʻona peaks i loko o ka spectrum ma hope o adsorption e 4A molecular kānana, e hōʻike ana i ka huahana o 4A molecular sieve adsorption o H 2 S odorous kinoea he elemental sulfur.

ʻO ka kānana molekala 4A i ka hoʻoheheʻe ʻana i ke kaomi ʻana he maʻalahi ke make a nalowale kāna hana, e hoʻōki i ka hana a pau.ʻO nā kānana molekala no ka hapa nui o ke kumukūʻai o PSA, a ʻo ke kumukūʻai o ka hoʻopaʻa ʻana o ka molecular sieve PSA oxygen enrichment lako e like me ke kumukūʻai o ka mālama ʻana i ka ikehu.Ma ka hana pono, kaomi kowali adsorption mea he 'enehana holomua, akā, i ka lako mea pipiʻi, ka molecular kānana i ka pōkole lawelawe ola, a me ka lako hana, Price like me ka loaʻa kālā hoʻokoe, ka mea e hana molecular kānana kaomi kowali adsorption kakaikahi i ka pono noi.

ʻO nā molekala kalapona e hana ana i ka nitrogen o ka 4A molecular sieve pressure swing adsorption equipment e maʻalahi i ka maʻi e nā molekele wai, nā kinoea corrosive, nā kinoea waikawa, ka lepo, nā molekele aila, a me nā mea ʻē aʻe, ka hopena i ka molecular inactivation.ʻO ka hapa nui o kēia inactivation hiki ʻole ke hoʻololi.Hiki ke hana hou ʻia ma ka holoi ʻana me ka ea hou a me ka wai inā makemake ʻia, akā ʻoi aku ka liʻiliʻi o nā molekala kalapona i hoʻāla hou ʻia ma mua o ka mea mua, ʻo ia ka mea a mākou i kapa ai he molecular sieve poisoning.
