Peneira molecular de carbono<\/h2>\n<p><\/p>\n<p>Do ponto de vista qu\u00edmico, o cloro, o cloreto de hidrog\u00e9nio e o carbono n\u00e3o reagem \u00e0 temperatura ambiente. Al\u00e9m disso, o teor de cloro e de cloreto de hidrog\u00e9nio no ar \u00e9 extremamente reduzido. Ent\u00e3o, como \u00e9 que o crivo molecular de carbono pode ser envenenado?<\/p>\n<p><\/p>\n<p>A peneira molecular de carbono tem muitos microporos. O g\u00e1s cloro e o cloreto de hidrog\u00e9nio podem reagir com as part\u00edculas s\u00f3lidas da poeira fina no ar e depositar-se na superf\u00edcie da peneira molecular de carbono. Embora a quantidade di\u00e1ria seja pequena, a superf\u00edcie da peneira molecular de carbono \u00e9 coberta por sedimentos ap\u00f3s alguns anos. Quando uma grande quantidade de peneira molecular de carbono \u00e9 lentamente bloqueada pelos poros, ela \u00e9 \"envenenada\".<\/p>\n<p><\/p>\n<h2>2.

As peneiras moleculares de ze\u00f3lito s\u00f3 podem ser \"envenenadas\" ao serem contaminadas por \u00f3leo. A ess\u00eancia n\u00e3o \u00e9 a rea\u00e7\u00e3o qu\u00edmica entre o \u00f3leo e as peneiras moleculares. Foi a mistura de \u00f3leo e poeira que bloqueou os poros da superf\u00edcie da peneira molecular.
