This disclosure is directed to an integrated method for making synthetic hydrocarbon fluids, plasticizers and polar synthetic lubricant base stocks from a renewable feedstock. More particularly, the disclosure is directed to a metathesis reaction of natural oil or its derivative ester and ethylene in the presence of an effective amount of a metathesis catalyst to form linear alpha-olefins, internal olefins and reduced chain length triglycerides. The linear alpha-olefins and/or internal olefins are polymerized to produce synthetic hydrocarbon fluids in the presence of a suitable catalyst. The reduced chain length triglycerides are converted into polar synthetic lubricant base stocks or plasticizers by hydrogenation, isomerization, followed by hydrogenations, or by hydroisomerization processes. Alternatively, the reduced chain length triglycerides can also be epoxidized to form epoxidized triglyceride plasticizers, optionally followed by carbonation, to form carbonated triglyceride plasticizers.
本公开涉及一种从可再生原料制备合成烃类流体、
增塑剂和极性合成润滑基础油的集成方法。更具体地,本公开涉及天然油或其衍生酯与
乙烯在存在有效量的交换催化剂的情况下进行交换反应,形成线性α-烯烃、内部烯烃和降低链长的
甘油三酯。在适当催化剂的存在下,线性α-烯烃和/或内部烯烃被聚合以产生合成烃类流体。降低链长的
甘油三酯经过氢化、异构化,然后再经过氢化,或者通过氢异构化过程转化为极性合成润滑基础油或
增塑剂。另外,降低链长的
甘油三酯也可以经过环氧化而形成环氧化
甘油三酯增塑剂,随后可选择进行碳化以形成
碳酸甘油三酯增塑剂。
