Methods of producing renewable base oils and renewable fuel components

본 발명은, 유리 지방산 및 글리세리드를 포함하는 생물학적 기원의 공급 원료로부터, 재생 가능한 기유 및 다른 가치있는 재생 가능한 연료 성분을 생산하는 방법에 관한 것이다. 공급 원료는 먼저 지방산 분획 및 글리세리드 분획을 포함하는 2개 이상의 유출물 스트림으로 분리된다. 글리세리드는 유리 지방산과 글리세롤로 가수 분해되고, 따라서 이렇게 획득된 지방산은 분리로 재순환된다. 이후, 지방산은 케톤화, 수소탈산소화 및 수소이성질체화에 의해 기유로 전환된다. 글리세롤은 선택적 수소분해에 의해 프로판올로 전환된다. The present invention relates to a process for producing renewable base oils and other valuable renewable fuel components from feedstocks of biological origin comprising free fatty acids and glycerides. The feedstock is first separated into at least two effluent streams comprising a fatty acid fraction and a glyceride fraction. The glycerides are hydrolyzed to free fatty acids and glycerol, and thus the fatty acids thus obtained are recycled to the separation. The fatty acids are then converted to base oil by ketonation, hydrodeoxygenation and hydroisomerization. Glycerol is converted to propanol by selective hydrogenolysis.

ETHYLENE α-OLEFIN BLOCK COPOLYMERS AND METHODS FOR PRODUCTION THEREOF

This invention relates to block polymers containing both cristalline and elastomeric blocks, the block copolymer having an A block and a B block. The A block is a polyethylene or an ethylene polymer optionally containing an alpha-olefin and is generally crystalline. The B block contains an ethylene, α-olefin copolymer segment and optionally contain an ethylene, α-olefin, non-conjugated diene terpolymer segment. If the B block contains a diene containing segment, the diene containing segment is furthest from the junction of the A and the B blocks. Also disclosed is a process for manufacture of the block copolymers and methods for coupling the block copolymers. Coupled block copolymers are useful as thermoplastic elastomers exhibiting physical properties approaching those of cross-linked EP or EPDM elastomers, but showing thermal processability after coupling. The block copolymers of the present invention may also be used as a lubricant or fuel additive, as a plastics blend component, in bitumen blends, as a component in hot melt adhesives and as a component of roof sheeting compounds.
