Abstract: A system for processing plastic waste may include a feed line, a feed fractionator, a hydrotreater, a catalytic reforming unit, a heavy oil cracker, and a steam cracker. A pyrolyzed plastics feed is separated into light, medium, and heavy hydrocarbon streams. The hydrotreater removes sulfur, and the catalytic reforming unit produces a circular aromatic-rich stream. The heavy oil cracker generates cracked streams. The steam cracker produces a circular olefin stream from a cracked stream. A system for processing plastic waste may include the feed line, the feed fractionator, the hydrotreater, a medium hydrocarbon fractionator, the catalytic reforming unit, a full-range reforming unit, the heavy oil cracker, and the steam cracker. The medium hydrocarbon fractionator produces two hydrocarbon streams. The full-range naphtha reforming unit produces a second circular aromatic-rich stream.

Abstract: An apparatus and method for manufacturing partially cut (semi-converted) products in continuous roll form has input feeds for supplying a continuous web of material and a continuous transport web in parallel, feed rollers for incrementally advancing the two webs together to a cutting station where product units are partially cut in successive increments in a continuous strip, a scrap remover, and a station for winding up the cut product strip. The webs are unwound and the cut product strip is wound via dancer bars maintaining constant tension. The input webs have a width which is a multiple of the width of the product units so that multiple strips can be formed simultaneously. The invention is used to form semi-converted, micro diskette liners having connecting portions and indented cutouts marking the boundaries between units. The cutouts are overcut in one direction and also in an intersecting direction to obtain complete cuts despite slight variations in registration.

Abstract: This invention is a trilobal, synthetic fiber, intended for use in carpets, having an axially extending hole in each lobe, the total cross-sectional area of the fiber being about 5 to 12 percent void, said fiber cross-section having a modification ratio of between about 2 to 3, and an arm angle of about 15.degree. to 45.degree., so that a fiber having improved bulk, soil hiding and resiliency is apparent in a carpet having face fiber of said fiber.
