A method of purifying a composition comprising a plastic liquefaction oil, comprising treating the composition to reduce the content of heteroatoms by treatment with a basic compound followed by washing, separation or separation followed by washing. The composition thus treated is then subjected to a gasification process to produce syngas comprising at least dihydrogen, carbon monoxide and carbon dioxide. Procédé de purification d'une composition comprenant une huile de liquéfaction de plas- tique, comprenant un traitement de la composition afin d'en réduire la teneur en hétéroa- tomes par traitement avec un composé basique suivi d'un lavage, d'une séparation ou d'une séparation suivie d'un lavage. La composition ainsi traitée est ensuite soumise à un procédé de gazéification pour produire du gaz de synthèse comprenant au moins du dihy- drogène, du monoxyde de carbone et du dioxyde de carbone.
