Process for stabilization of reactive liquid feedstock

A process for conversion of a reactive liquid feedstock stream containing at least 40 wt % carbon into a stabilized composition, comprising the steps of

• a. directing a diluent stream and the reactive liquid feedstock stream as a combined stream having a first hydrogen consumption potential, to contact a material catalytically active in hydrotreatment which during operation has a lowest temperature of at least 80° C. and a highest temperature of less than 250° C. in the presence of dihydrogen,
• b. withdrawing a stabilized composition stream having a second combined hydrogen consumption potential which is less than 80% and more than 10% of the first hydrogen consumption potential,
• c. withdrawing a combined liquid and gas phase stream from the stabilized composition stream by overflow, and
• d. withdrawing an amount of a liquid phase of said stabilized composition stream by flow control and providing it as said diluent stream
• wherein the hydrogen consumption potential for a composition shall be understood as the amount of hydrogen required for conversion of the composition into a saturated hydrocarbon.
