摘要： Disclosed is an apparatus for detecting the location of the interface between two phases of matter of substantially different conductivity. The apparatus includes a plurality of insulated conductive members spaced along an axis and adapted for suitable electrical connections whereby it may be determined which of the conductive members are immersed in the conductive phase and which are in the non-conductive phase.

摘要： A resid hydrocarbon is converted to lower boiling hydrocarbons and/or desulfurized by contacting, in the presence of hydrogen, said resid with a bed of catalyst particles, substantially all of said particles having a surface-to-volume ratio ranging between about 100 and about 250 l/inches, and wherein substantially all points within each of said particles are less than about 0.015 inch from the particle''s surface. When one of these particles is circumscribed by a right circular cylinder having an altitude equal to that of the particle, the particle contacts the sidewall of the cylinder at at least three elements and occupies from about 70 to about 90 percent of the cylinder''s volume. Preferred particle shapes are clover-leaf, cross, ring and C-shape.
