WebThe first reports of FCC iron poisoning on a large-scale date from the 1990s. Iron was used in drilling liquids for oil recovery. Iron poisoning results in a loss of activity and an increase in slurry yield. The apparent bulk density of the catalyst decreases, which causes a drop in pressure differential over the standpipes and can lead to erratic catalyst circulation. philips avent newborn teatWebIf the density of the respective fractions are 3.6, 3.68 and 3.86 gm/cm3 and the ultimate density is 4.0 gm/cm3, calculate the interparticle and intraparticle porosity.
