ASSOCIATIVE POLYMERS FOR MIST-CONTROL
Polymeric mist control materials, methods of forming polymeric mist control materials, and methods of using such materials for mist control are provided. The polymeric mist control additives are formed of molecules comprised predominantly of monomers that confer high solubility in fuel and include associative groups that attract each other in donor-acceptor manner, and are incorporated such that multiple associative groups are in close proximity (“clusters”), such that the clusters are separated by very long non-associative sequences.

The invention relates to polymer compositions with improved manageability, The invention also relates to a polymer composition obtainable by radical polymerisation of A) 95-40 wt. % of a monomer mixture comprising Ai) 65-98 wt. % of at least alkyl (meth)acrylate having a linear C.sub.16-C.sub.40 alkyl radical and Aii) 2-35 wt. % of at least one comonomer selected from (meth)acrylates and (meth)acrylamides, which supports an optionally substituted aromatic radical bonded via an alkylene, alkenylene, oxyalkylene or polyoxyalkylene group to the ester group of the (meth)acrylate or to the amide group of the (meth)acrylamide, in the presence of B) 5-60% by weight % of at least one ethylene copolymer. The invention further relates to a method for the preparation and use thereof as flow improvers for paraffin-containing hydrocarbon oils.
ADDITIVES FOR WINTERIZATION OF PARAFFIN INHIBITORS
A winterized paraffin inhibitor, which is capable of being used for preventing the deposition of paraffins in hydrocarbon streams and capable of withstanding freezing or crystallization at freezing or sub-freezing temperatures, may be formed by adding an oxyalkylated branched aliphatic compound having 12 or more carbons to a high molecular weight aliphatic polymer paraffin inhibitor, the oxyalkylated branched aliphatic compound having 12 or more carbons being produced by the oxyalkylation of the branched aliphatic compound having 12 or more carbon atoms in which the branched aliphatic compound having 12 or more carbon atoms is grafted with a polyether via a ring-opening reaction, wherein the polyether is a polymer of ethylene oxide, propylene oxide, butylene oxide, and combinations thereof.
Systems and methods of converting renewable feedstocks into intermediate hydrocarbon blend stocks and transportation fuels
Systems and methods to provide renewable transportation fuels for internal combustion engines by converting renewable feedstocks into two or more intermediate hydrocarbon blend stocks and blending at least two of the two or more intermediate hydrocarbon blend stocks to produce the renewable transportation fuel. Methods and/or processes may include selecting sugar from a sugar source and introducing the sugar into one or more reactors. The sugar may be converted into an intermediate renewable hydrocarbon blend stock and sent to a separation unit to separate out an intermediate renewable gasoline unit. The process may include selecting and converting a lipid from a lipid source into a renewable diesel product. The renewable diesel product may be sent to a second separation unit to separate out renewable diesel and a low-grade naphtha. The low-grade naphtha and intermediate renewable gasoline may be blended to define a finished renewable gasoline.
FCC CO-PROCESSING OF BIOMASS OIL
Systems and methods are provided for improving product yields and/or product quality during co-processing of fast pyrolysis oil in a fluid catalytic cracking (FCC) reaction environment. The systems and methods can allow for co-processing of an increased amount of fast pyrolysis oil while reducing or minimizing coke production for a feedstock including fast pyrolysis oil and a conventional FCC feed. The reducing or minimizing of coke production can be achieved in part by adding a low molecular weight, non-ionic surfactant to the mixture of fast pyrolysis oil and conventional FCC feed.
