Embodiment

[0192] Animal fat (AF) derived from food industry waste was blended with crude palm oil (CPO) to obtain a mixture of 50 wt-% AF and 50 wt-% CPO. This biorenewable oil / fat feedstock is first pretreated to remove major impurities by bleaching. Following this, the pretreated feedstream was processed by hydrodeoxygenation (HDO) to produce a biohydrocarbon feed under the conditions specified below. The biohydrocarbon stream is separated and purified to provide a propane feed. Table 1 shows the heteroatom impurities in the biorenewable oil / fat feedstock before pretreatment.

[0193] bleach

[0194] The biorenewable re-oil / fat feedstock was bleached by adding 2000 ppm citric acid, 0.2 wt-% water and 1 wt% fuller's earth to the heated feedstock. These were mixed for 20 minutes at 80°C, after which time the material was dried using vacuum filtration.

[0195] Hydrodeoxygenation

[0196] The pretreated feedstock is then hydrodeoxygenated in the presence of hydrogen and a catalyst. ...

Abstract

Provided is a method for upgrading a bio-based material, the method comprising the steps of pretreating bio-renewable oil(s) and / or fat(s) to provide a bio-renewable raw material, deoxygenating the bio-renewable raw material, followed by separation, to provide a propane feed, and subjecting the propane feed to dehydrogenation and to separation to provide a propylene material.

Description

technical field [0001] The present invention relates to a process for the production of biorenewable propylene (propene) from oil and / or fat. In particular, the present invention relates to a method of subjecting naturally occurring (renewable) oils and / or fats to hydrogenation, separating a propane feed from the hydrogenated product and subjecting the propane feed to dehydrogenation to provide propylene after purification / separation material method. The propylene material can then be further processed. Background technique [0002] Propylene is the base material for several high-volume chemicals such as acrylic acid, propylene oxide and polypropylene which consume about 2700 kt, 9000 kt and 60 000 kt per year respectively. Acrylic acid is mainly used in the production of superabsorbents, coatings and paints. Propylene oxide is a precursor to several high-volume chemicals such as butylene glycol, polyether polyols, and propylene glycol. Polypropylene (PP) is the second m...
