Abstract: Provided is a method for upgrading polymer waste-based material. The method includes providing a polymer waste-based feedstock, providing a crude oil-derived feedstock, blending the polymer waste-based feedstock, the crude oil-derived feedstock, and optionally a further feed material, to provide a feed mixture, hydrotreating the feed mixture at hydrodesulphurisation conditions to provide a hydrotreated material boiling in the middle distillate range, and recovering at least a jet fuel component from the hydrotreated material.

Abstract: The present disclosure relates to methods for processing liquefied waste polymers (LWP) containing diolefins. The LWP feed is supplied to steam stripper A to provide a distillate containing diolefins and naphtha, and a distillate bottom. The distillate is subjected to hydrotreatment B to produce a diolefin depleted distillate which is separated by distillation C to give rise to one or more fractions comprising at least a naphtha fraction, an optional middle fraction and a bottom fraction. Hydroprocessing D of the naphtha fraction gives rise to hydrogenated naphtha which is suitable as a feed for a steam cracker E. Since the distillation bottom, bottom fraction and the middle distillate are predominantly free from diolefins, they can be mixed with crude oil and processed further in oil refinery.

Abstract: A method is disclosed of purifying a recycled or renewable organic material, wherein the recycled or renewable organic material includes more than 1 ppm silicon as silicon compounds. Exemplary steps include (a) providing the recycled or renewable organic material; (b) heat treating the recycled or renewable organic material to form a heat treated recycled or renewable organic material, wherein the at least part of silicon compounds present in the recycled or renewable organic material are converted to volatile silicon compounds, and (c) evaporating volatile silicon compounds from the heat treated recycled or renewable organic material to obtain recycled or renewable organic material fraction containing less silicon than the recycled or renewable organic material provided in step (a).

Abstract: The present disclosure relates to a method for upgrading liquefied waste plastics, the method including a step (A) of providing liquefied waste plastics (LWP) material, a step (B) including pre-treating the liquefied waste plastics material by contacting the liquefied waste plastics material with an aqueous medium having a pH of at least 7 at a temperature of 200° C. or more, followed by liquid-liquid separation, to produce a pre-treated liquefied waste plastics material, a step (C) including hydrotreating the pre-treated liquefied waste plastics material, optionally in combination with a co-feed, to obtain a hydrotreated material, and a step (D) of post-treating the hydrotreated material to obtain a steam cracker feed.
