A single tube catalyst loading device is provided which consists of a transport belt system, electric motor, and catalyst loading hopper. Using this equipment, it is possible to control the drop rate of catalyst pellets without incurring mechanical damage or breakage of the catalyst. By raising or lowering the hopper section above the transport belt, it is possible to increase or decrease the drop rate of catalyst. Drop rate is the critical parameter in controlling catalyst density within the tubes of an ethylene oxide reactor.

A device for transporting particulate material comprising: a support stand assembly including a generally horizontally disposed support base having a particulate material receiving section and a particulate material discharge section, and an upright support stand member fixed to said support base; an endless transport belt assembly connected to said support base for transporting the particulate material between said receiving and discharge sections of said support base; a loading hopper having an upper hopper inlet to allow particulate material to be introduced thereinto, and a lower hopper outlet to allow particulate material to be discharged therefrom; and a hopper mounting assembly for mounting the hopper laterally of said upright support stand member so that said hopper outlet is in juxtaposed relationship to said particulate material receiving section of said support base, wherein said hopper mounting assembly includes, (i) a hopper support bracket radially extending between said hopper and said upright support stand member; (ii) a hopper adjustment assembly which connects said hopper support bracket to said upright support stand member for vertically moving said hopper so as to permit vertical height adjustments of said lower hopper outlet relative to said transport belt at said particulate material receiving section to thereby control discharge rates of the particulate material from the transport belt at said discharge section; and (iii) a lateral support brace positioned below and substantially parallel to said radially extending support bracket, said lateral support brace having a proximal end rigidly connected to said hopper and an opposite distal end in sliding contact with said upright support member so as to buttress said hopper against said upright support member.
