Abstract: The present invention relates to a method of deoxygenating tall oil pitch, yielding aliphatic and aromatic hydrocarbons. The invention even comprises turning the aliphates into polymerizable olefins by steam cracking, and turning the aromates into polymerizable terephthalic acid by oxygenation and, as necessary, rearrangement. The monomers can be used for the production of polymers of partially or completely biologic origin. According to the invention, tall oil pitch is first heated to turn it into liquid, which is then fed into a catalyst bed and catalytically deoxygenated with hydrogen. The deoxygenation catalyst is preferably a Ni—Mo catalyst and, in addition, a cracking catalyst can be used, such as an acidic zeolite catalyst. The deoxygenated product stream is cooled down so as to obtain a liquid, which is distilled for separation of the aliphatic and aromatic hydrocarbons for use in the production of the respective monomers and finally polymers.

Abstract translation: 本发明涉及一种使妥尔油沥青脱氧，产生脂族和芳族烃的方法。 本发明甚至包括通过蒸汽裂化将脂族物转化为可聚合烯烃，并且通过氧合将需要的芳烃转化为可聚合的对苯二甲酸，并且根据需要进行重排。 单体可用于生产部分或完全生物来源的聚合物。 根据本发明，首先将妥尔油沥青加热以将其转化成液体，然后将其进料到催化剂床中并用氢催化脱氧。 脱氧催化剂优选为Ni-Mo催化剂，此外，可以使用裂化催化剂，例如酸性沸石催化剂。 将脱氧产物流冷却，以获得液体，蒸馏用于分离用于生产各单体和最终聚合物的脂族和芳族烃。

Abstract: A deep-drawn paper tray made of paper material, a method and an apparatus for manufacturing the tray, and a closed product package comprising the tray. The tray having a bottom and upwardly expanding side walls around the bottom, the side walls of the tray being shaped to expand through a plurality of circumferential steps dimensioned low enough for obtaining wrinkle-free side walls for the tray. The outermost step is a flat, wrinkle-free rim flange, which enables liquid and gas proof heat-sealing of a lid to form the package. The apparatus may comprise upper and lower moulding tools with concentric movable frames for forming the tray bottom and side wall steps from paper blanks, and moulding tools may be mounted onto a rotating turret carrying a paper blank through working stations arranged along the turret circumference, to shape the tray bottom and the side wall steps at the consecutive stations.
