Abstract: Disclosed herein is a method to make 5-(alkoxycarbonyl) furan-2-carboxylic acids (ACFC) from feedstocks comprised of furoates. When a feedstock comprised of methyl 5-methylfuran-2-carboxy late (MMFC) is used a product comprised of (5-(methoxy carbonyl) furan-2-carboxylic acid (MCFC) is obtained in high yield.

Abstract: A hydrocarbon cracker stream is combined with recycle content pyrolysis oil to form a combined cracker stream and the combined cracker stream is cracked in a cracker furnace to provide an olefin-containing effluent. The r-pyoil can be fed to the cracker feed. More specifically the-pyoil is present in said feedstock in an amount of not more than 20% by weight, based on the total weight of the feedstock.

Abstract: Processes and systems for making recycle content hydrocarbons, including olefins, from recycled waste material. Recycle waste material may be pyrolyzed to form recycle content pyrolysis oil composition (r-pyoil), at least a portion of which may then be cracked to form a recycle content olefin composition (r-olefin). In some cases, the pyrolysis and cracking may be carried out in different sections of the same furnace, or in different furnaces in the same cracker facility. Pyrolysis conducted in a furnace may or may not require retrofitting a furnace previously used to crack alkanes to form olefins.

Abstract: A composition having a recycle content value is obtained by reacting a recycle content feedstock to make a recycle content alpha olefin or by deducting from a recycle inventory a recycle content value applied to an alpha olefin composition. At least a portion of the recycle content value in the feedstock or in an allotment obtained by an alpha olefin manufacturer has its origin in recycled waste and/or pyrolysis of recycled waste and/or in thermal steam cracking of recycle content pyoil.

Abstract: A composition obtained by combining virgin cellulose fibers, cellulose ester (CE) staple fibers having a denier per filament (DPF) of less than 3, and water, and water. The CE staple fibers can also have a short cut length of less than 6 mm and can be crimped. The compositions, when co-refined, are useful to make wet laid products such as paper, cardboard, and filters that have improved water drainage, air permeability, tensile strength, bulk, burst strength, or stiffness, or a combination of these properties.

Abstract: The present invention provides compositions comprising cellulose fibers and cellulose ester fibers and wet laid articles made from the compositions, as well as wet laid processes to produce these compositions. More specifically, the present invention provided compositions comprising cellulose fibers and cellulose acetate fibers and wet laid articles made from these compositions as well as wet laid processes to produce these compositions. The present invention also relates to developing a composition, process, wet laid product, or articles exhibiting any one of many desired benefits. Specifically, a wet laid process comprising a process that allows the quantity of water removed from a web passed through press rolls is increased relative to a web made from a 100% cellulose comparative composition.

Abstract: A recycled cellulose pulp composition is provided which comprises recycled cellulosic fibers and cellulose ester staple fibers. The recycled cellulose pulp containing co-refined re-cycled cellulose fibers and cellulose ester staple fibers can be added to a hydropulper and fed back through a refiner to make wet laid products.

Abstract: Absorbent wet laid products are made containing cellulose fibers and cellulose ester staple fibers that are co-refined to obtain products and articles that have improved water absorbency and tensile strength or burst strength or both. The absorbent wet laid products can now be made with a synthetic fiber in the wet laid operation since cellulose ester can be subjected to a refining operation.

Abstract: A wet-laid fibrous product is provided that comprises recycled cellulosic fibers, cellulose ester staple fibers, and residual recycled ink, where the fibrous product has less ink content compared to the ink content for a 100% cellulose comparative fiber wet-laid product, when processed under similar conditions. The wet-laid fibrous product can be formed from a deinked recycled paper pulp slurry, the pulp slurry comprising recycled cellulosic fibers, cellulose ester staple fibers, and ink. A deinking process for the slurry is also provided.
