Abstract
Inventia se refera la un catalizator de dehidrogenare a hidrocarburilor alchilaromatice pe baza de oxizi de fier, oxizi de crom, oxid de vanadiu si carbonat de potasiu. Acest catalizator are o selectivitate si stabilitate superioara catalizatorilor cunoscuti si se obtine pornind de la alfa Fe IIH care se transforma în alfa-Fe2O3 cu continut de 1-10% alfa FeOOH prin tratament hidrotermal la 190-210 degree C, volum constant, presiune de 16-20 at, sub agitare, timp de 1-4h, adaosurile de oxid de crom si vanadiu putandu-se face, fie înainte fie dupa prepararea oxizilor de fier hidrotermal.The invention relates to a dehydrogenation catalyst of alkylaromatic hydrocarbons based on iron oxides, chromium oxides, vanadium oxide and potassium carbonate. This catalyst has a superior selectivity and stability to the known catalysts and is obtained from alpha Fe IIH which is converted to alpha-Fe 2 O 3 containing 1-10% alpha FeOH by hydrothermal treatment at 190-210 ° C, constant volume, pressure 16-20 ° C with stirring for 1-4 hours, the chromium and vanadium oxide additions being made either before or after the preparation of hydrothermal iron oxides.
