A porous catalyst has an internal surface area of 800 m2 per m3 of bulk material. Fifty percent of the bulk volume consists of the pores (holes), while the other 50% of the volume is made of solid substance. Assume that the pores are cylindrical tubules of uniform diameter, d, and length, l, and that the measured surface area is the total area of the curved surfaces of the tubules. What is the diameter of the pores?

Answer» A porous catalyst has an internal surface area of 800 $m^{2}$ per $m^{3}$ of bulk material. Fifty percent of the bulk volume consists of the pores (holes), while the other 50% of the volume is made of solid substance. Assume that the pores are cylindrical tubules of uniform diameter, d, and length, l, and that the measured surface area is the total area of the curved surfaces of the tubules. What is the diameter of the pores?
