Provided is a method for upgrading a bio-based material, the method including the steps of pre-treating bio-renewable oil(s) and / or fat(s) to provide a bio-based fresh feed material, hydrotreating the bio-based fresh feed material, followed by separation, to provide a bio-propane composition.

Provided is a continuous process for converting waste plastics into recycling for polypropylene polymerization. This process includes a step of selecting waste plastics containing polyethylene and / or polypropylene, and a step of preparing a blend of the biofeedstock and the selected plastics. The amount of plastic in the blend constitutes 20 wt% or less of the blend. The blend is passed through an FCC unit. A liquefied petroleum gas LPG olefin / paraffin mixture and naphtha are recovered from the FCC unit and can be used in the production of polypropylene.

Disclosed is oligomerization of ethylene to form 1-hexene in combination with aromatization of the 1-hexene formed by oligomerization, to form benzene.

Provided is a continuous process for converting waste plastics into recycling for the production of chemical substances. This process includes a step of selecting waste plastics containing polyethylene and / or polypropylene, and a step of preparing a stable blend of the biofeedstock and the selected plastics. The amount of plastic in the blend constitutes 20 wt% or less of the blend. The blend is passed through a conversion unit. Useful chemical substances including C3 and C4 olefins and aromatics are recovered.

Provided is a continuous process for converting waste plastic into recycle for polyethylene polymerization. The process comprises selecting waste plastics containing polyethylene and / or polypropylene and preparing a blend of a bio feedstock and the selected plastic. The amount of plastic in the blend comprises no more than 20 wt. % of the blend. The blend is passed to a FCC unit. A liquid petroleum gas LPG olefin / paraffin mixture and naphtha are recovered from the FCC unit and can be passed on to make polyethylene.
