1. A gas-solid contacting system with structured packing (108), the structured packing (108) comprising:
a gas header (102) with an inlet to receive a gas;
a plurality of vertically aligned tubes (104) fluidically connected to the gas header (102), wherein each vertically aligned tube (104) comprises openings (180) to distribute the gas at different heights in a radial direction; and
a structured packing element (106) arranged on each vertically aligned tube (104), wherein the structured packing element (106) comprises one or more plates attached to the vertically aligned tube (104) to create a convoluted 3-dimensional flow path of a solid particulate stream.
