The embodiments disclosed herein can provide a process for converting a hydrocarbon feed. The process may include hydrocracking the hydrocarbon feed slurried with a particulate catalyst in a presence of hydrogen in a hydrocracking reaction zone to produce a hydrocracked stream, separating at least a portion of the hydrocracked stream, and passing the at least the portion of the hydrocracked stream through a thermal cracking heating zone at conditions effective for thermally cracking the at least the portion of the hydrocracked stream.
