PURPOSE:To reuse residual catalyst active components for a reaction, and to economize the quantity of a new catalyst to be supplied, by a method wherein catalyst inactive components are removed from a reaction forming liquid obtained by converting hydrocarbon by using a catalyst. CONSTITUTION:Hydrocarbon is converted into isomerization, polymerization, etc. by employing a fluoride compound of a general formula X<+>MF6<-> (where, X is hydrogen or hydrocarbon and M niobium, antimony or tantalum atoms) as a catalyst. In this case, catalyst inactive components with comparatively large specific gravity are removed from a catalyst liquid after using the said compound or a mixture of the catalyst liquid and hydrocarbon as a sludgy, heavy fluid or crystalline matter. Residual catalyst active components are reused for a hydrocarbon converting reaction. Thus, since the catalyst active components are reused, the quantity of a new catalyst supplied is economized, and hydrocarbon is economically conversion- reacted. |
