    摘要： A catalyst for producing phenol consisting essentially of a nickel compound supported on a metal oxide carrier, or a catalyst for producing phenol consisting essentially of iron oxide and nickel oxide, and processes for producing phenol using either of the above catalyst. The catalysts of the invention exercise a high conversion of benzoic acid and a high selectivity to phenol, and phenol can be produced in a high yield, particularly in a high space time yield through the processes of the invention using the above catalysts. The above conversion, selectivity and space time yield can be improved by calcining the catalyst at 600.degree. to 900.degree. C.

    摘要： A solid catalyst used in, for example, production of a perfluoroalkyl iodide telomer is effectively and continuously recovered and the recovered catalyst is continuously recycled to the reactor for reuse. A slurry containing a reaction product and the catalyst is drawn from the reaction system, and the catalyst in the drawn slurry is classified by means of a hydrocyclone, whereby a high-concentration slurry whose catalyst concentration is higher than that of the drawn slurry and a low-concentration slurry whose catalyst concentration is lower than that of the drawn slurry are obtained, and the high-concentration slurry is recycled to the reaction system.
