Process for hydrocarbon conversion with on-line solid particulate material removal

A process for conversion of a hydrocarbon feedstock, comprising the steps of:

• A) feeding said hydrocarbon feedstock to an adsorption unit;
• B) adsorbing said hydrocarbon feedstock in said adsorption unit with a solid particulate adsorbent useful for adsorbing at least one component from said hydrocarbon feedstock under adsorption conditions;
• C) withdrawing adsorbed hydrocarbon feedstock from said adsorption unit;
• D) desorbing said at least one adsorbed component from said solid particulate adsorbent;
• and
• E) removing, under said adsorption conditions, at least a portion of said solid particulate adsorbent while said hydrocarbon feedstock is being fed to said adsorption unit, wherein said portion is more than 0.1 wt. % of said solid particulate adsorbent in said adsorption unit and wherein said adsorbent removal occurs during a fraction of the time of step (B), said fraction being less than about 20% of the time of step (B).
