ABSTRACT:
A modular multi-tube catalyst loading funnel comprises a series of funnel modules, each equipped with a rotatable stirring rod, an opening at the bottom, and a variable-speed drive. With the apparatus, it is possible to control the drop rate of catalyst pellets in each of the funnels, by adjusting the speed of rotation of the metering rods. If more control is required, the metering rods may be raised or lowered in each funnel module to increase or decrease the speed of catalyst drop. Additionally, it is possible to utilize metering rods with various end configurations to alter the speed of the catalyst drop in the multitube catalytic reactors.
