Abstract: Disclosed is a fuel additive system for internal combustion engines in which the fuel additive system is disposed on-board a vessel such as marine vessel or locomotive. The fuel additive system includes a fuel additive reservoir containing a fuel additive in fluid communication with an internal combustion engine. An electronically controlled injector, such as an eductor, is in fluid communication with the internal combustion engine and a fuel level meter or sensor, fuel efficiency meter or sensor, or other meter or sensor which, upon sensing certain pre-set conditions, e.g., increase of fuel level in a fuel storage tank or decrease in fuel efficiency, the injector injects an appropriate amount of fuel additive from the fuel additive reservoir and into the fuel stream that ultimately enters the internal combustion engine.

Abstract: A crude oil composition wherein fouling has been mitigating and a method for mitigating crude oil fouling. The composition includes crude oil and an improved dispersant material for mitigating fouling which comprises a reaction product of a polyamine and a polyisobutylene succinyl anhydride made with a polyisobutylene having a vinylidene double bond content of at least 50%. The reaction product has an active nitrogen atom content of at least about 2% by weight. The reaction product is prepared by thermally reacting the polyisobutylene with maleic anhydride to produce said polyisobutylene succinyl anhydride and thereafter reacting the polyisobutylene succinyl anhydride with a polyamine having 5 to 7 active nitrogen atoms. The method includes providing the dispersant material and dispersing the same in crude oil.

Abstract: The present invention includes a flow enhancement composition and a method for enhancing flow using the flow enhancement composition in relation to liquid and gaseous flow in pipes, tubes, conduits and other transfer or transmission devices, particularly metallic.

Abstract: The present invention provides a fuel additive and a process for using and making the fuel additive. The fuel additive includes a non-acidic boron-containing salt in a carrier fluid. The fuel additive enhances combustion by increasing fuel efficiency or decreased pollutant output in an exhaust gas resulting from combustion of the fuel with the fuel additive.

Abstract: A mid-range vinylidene content PIB polymer composition made by a liquid phase polymerization process conducted in a loop reactor at a temperature of at least 60° F. using a BF3/methanol catalyst complex and a contact time of no more than 4 minutes. At least about 90% of the PIB molecules present in the product comprise alpha or beta position isomers. The vinylidene (alpha) isomer content of the product may range from 20% to 70% thereof, and the content of tetra-substituted internal double bonds is very low, advantageously no more than about 10%, preferably less than about 5% and ideally less than about 1-2%.

Abstract: Polyolefin product produced using process conducted in apparatus for olefin polymerization which includes one or more shell and tube olefin polymerization reactors, each of which has an olefin polymerization reaction mixture inlet connection and a crude polyolefin product outlet connection. Each reactor is equipped with a recirculation system including a pump arranged to circulate a reaction mixture through the tube side of the reactor independently of the introduction of olefin polymerization reaction mixture into the reactor. The apparatus may also include an inlet reaction mixture distribution manifold and an outlet polymerization reaction mixture collection manifold interconnecting the reactors for operation in parallel. The apparatus also includes catalyst composition and catalyst modifier inlets for each reactor arranged such that a catalyst modifier to may be introduced into each reactor at a rate which is independent of the introduction of catalyst composition.

Abstract: A novel liquid phase polymerization process for preparing a polyolefin product having preselected properties is disclosed. The process includes the steps of providing a liquid feedstock which contains an olefinic component and a catalyst composition consisting of a stable complex of BF3 and a complexing agent therefor. The feedstock may comprise any one or more of a number of olefins including branched olefins such as isobutylene, C3 to C15 linear alpha olefins and C4 to C15 reactive non-alpha olefins. The feedstock and the catalyst composition are introduced into a residual reaction mixture recirculating in a loop reactor reaction zone provided in the tube side of a shell and tube heat exchanger at a recirculation rate sufficient to cause intimate intermixing of the residual reaction mixture, the added feedstock and the added catalyst composition.
