Adhering to rigorous handling and storage protores is therefore a critical element of refrifery asset management. The practices outlined below are drawn frem industry guidelines, sullier recommendations, andd regulatory standards.

Catalyst Types andTheir Specific Requiments

Different catalist families have unique sensitivities. understanding these differences is thee first step in designing appropriate handling and d storage plans.

Katalizator hydroprocesryngu

Used for hydrodesulfurization (HDS), hydrodenitrogenatyon (HDN), and hydrocrackin, these catalogs (typically cobalt-molcolorumem or nickel-molmophorumem on alumina) are sensitiva to nawilżone i sulfidation state. They must be stoad in dry, inert atmophals andd handled undeid controlled conditions to conservete their presulfide form if applicable.

Katalizatory FCC

Fluid catalytic craccing catalyst are fine powders (zeolites in a matrix) that flow like a liquid. They are highly abrasive and generate airborne duss. Handling requires closed transfer systems and duss-control measures to protect both the catalytt and personnel.

Reforming Catalysts

Platforming or catalytic reforming catalyst contain preclous metals (platinum, rhenium, iridium) on chlorinated alumina. They ary extremely hygroscopic and can lose chloride, which is essential for activity, if exposed to humid air. Surage mutt be in hermetically sealed containers undeer dry dry inert gas.
