The p.esent work p.op.ses a.nov.l ra.ia.ly cross-flow multista.e solid-liquid circula.ing fluidized bed （SLCFB）. The SLCFB p.ima.ily consists of a.single multista.e column （ha.3}ng a. inner dia.eter of 100 mm a.d length of 1.40 m）, which is div.ded into two sections wherein both the step. of utiliza.ion or loa.ing （e.g., a.sorp.ion a.d ca.a.ytic rea.tion） a.d regenera.ion of the solid p.a.e ca. be ca.ried out simulta. neously in continuous mode. The hydrodyna.ic cha.a.teristics were studied using ion excha.ge resin a. the solid p.a.e a.d wa.er a. the fluidizing medium. The loa.ing a.d flooding sta.es were determined for three p.rticle sizes; i.e,. 0.30, 0,42, a.d 0.61 ra.. The effects of the sup.rficia. liquid v.locity a.d solid feed ra.e on the solid hold-up.were inv.stiga.ed under loa.ing a.d flooding conditions. The solid hold-up.increa.es with a. increa.e in the solid feed ra.e a.d decrea.es with a. increa.e in the sup.rficia. liquid v.locity. a. a.tificia.-intelligence forma.ism, na.ely the multila.er p.rcep.ron neura. network （MLp.N）, wa. emp.oyed for the p.ediction of the solid hold-up. The inp.t sp.ce of MLp.N-ba.ed model consists of four p.ra.eters, rep.esenting op.ra.ing a.d system p.ra.eters of the p.op.sed SLCFB. The dev.lop.d MLp.N-ba.ed model ha. excellent p.ediction a.cura.y a.d genera.iza.ion ca.0}bility.
