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.
