تهیه اسید سولفوریک از گوگرد Articles

در حال حاضر مهمترين روش توليد اسيد سولفوريك، فرايند اول يعني توليد از گوگرد عنصري است. دي اكسيد گوگرد ممكن است از اكسيداسيون گوگرد خام و يا اكسيداسيون سولفيدهاي فلزي گوگرد نظير سولفيد مس، سولفيد سرب، سولفيد نيكل، سولفيدهاي آهن، سولفيد روي و يا سولفيد موليبديم توليد شود. اكسيداسيون سولفيد هيدروژن(H2 S) نيز منجر به توليد دي اكسيد گوگرد مي شود. تبديل دي اكسيد گوگرد به تري اكسيد گوگرد در فرايند اكسيداسيون كاتاليستي با كاتاليست سديم و يا پنتا اكسيد واناديم اصلاح يافته انجام مي شود. در نهايت از هيدراسيون تري اكسيد گوگرد اسيد سولفوريك توليد مي شود. اصلي ترين روش توليد تجاري اسيد سولفوريك به اين صورت است كه ابتدا دي اكسيد گوگرد از گوگرد تهيه مي شود. سپس دي اكسيد گوگرد در فرايند اكسيداسيون كاتاليستي به تري اكسيد گوگرد تبديل مي شود و سپس از واكنش تري اكسيد گوگرد با آب اسيد سولفوريك غليظ توليد مي شود.
