摘要： A composition including a polyalphaolefin and at least one alfol alcohol that function as drag reducing agent slurries and a process for the preparation of the drag reducing agent slurries are disclosed. The process includes contacting alpha olefin monomers with a catalyst in a reactant mixture to form a polyalphaolefin. The polyalphaolefin is combined with at least one alfol alcohol to form a drag reducing agent slurry. A process for reducing drag in a conduit is also disclosed.

摘要： The present invention is directed to improved drag reducing agents and methods of forming improved drag reducing agents comprising the steps of isomerizing olefin monomers to form isomerized olefin monomers, polymerizing the isomerized olefin monomers in the presence of at least one catalyst to form a polyolefin drag reducing agent having unexpectedly superior drag reduction properties when combined with liquid hydrocarbons, such as viscous crude oil. Therefore, the drag reducing agents of the present invention may be introduced into conduits, such as pipelines, to increase the flow of the hydrocarbons through the conduit.

摘要： A composition including an alcohol absorbed polyalphaolefin that functions as a drag reducing agent and a process for the preparation of the drag reducing agent are disclosed. The process includes the steps of contacting alpha olefin monomers with at least one catalyst in a reactant mixture to form a polyalphaolefin. The polyalphaolefin is then contacted with at least one water insoluble alcohol for a period of time to provide an alcohol absorbed polyalphaolefin that is used as an improved drag reducing agent. Processes for reducing drag in a conduit are also disclosed.

摘要： A composition including a polyalphaolefin and at least one alpha olefin monomer partitioning agent that function as drag reducing agents and a process for the preparation of the drag reducing agents are disclosed. The process includes the steps of contacting alpha olefin monomers with at least one catalyst in a reactant mixture to form a polyalphaolefin. The reactant mixture may include at least one alpha olefin partitioning agent or the at least one alpha olefin partitioning agent may be mixed with the polyalphaolefin after polymerization. The alpha olefin monomer partitioning agents are alpha olefin monomers that are solid at ambient temperatures. Preferably, the alpha olefin monomers are selected from the group consisting of C20-C60 alpha olefin monomers. A process for reducing drag in a conduit is also disclosed.
