Mechanical implant to reduce back pressure in a riser reactor equipped with a horizontal tee joint connection

摘要

An apparatus to reduce the pressure drop in a riser reactor equipped with a horizontal tee joint connection which uses a mechanical implant located at a point juxtaposed the connection of the horizontal and vertical tubes to prohibit fine particle catalysts from backflow down through the elongated riser reactor which thereby provides an easy upflow of catalysts through the riser reactor.
