Abstract

This invention provides feed introduction devices, and processes for using same, which minimize catalyst clogging. In particular, the invention is to a feed introduction device having a first end in fluid communication with a feed source, a second end in fluid communication with a reactor and a deviation zone between the first end and the second end to deviate the flow of feed about a deviation angle from the first end toward the second end. According to the invention, the deviation angle is greater than 90 degrees.
