Abstract: Methods for removing sulfur from a gas stream prior to sending the gas stream to a gas separation membrane system are provided. Two schemes are available. When the sulfur content is high or flow is relatively high, a scheme including two columns where one tower is regenerated if the sulfur concentration exceeds a preset value can be used. When the sulfur content is low or flow is relatively low, a scheme including one column and an absorption bed.

Abstract: Disclosed herein are an asphalt concrete mixture, an asphalt binder composition, and methods of preparing the related compositions. The asphalt binder compositions include a polyphosphoric acid, a macromolecular polymer having a saturated backbone with macromolecular modifications, sulfur, and non-surfactant additives based on wax chemistry. The compositions are capable of being performance graded and being used in warm mix asphalt applications.

Abstract: A pressure sensitive adhesive/cohesive exhibits excellent cohesive body properties, and other desirable features, even when exposed to heat and polysiloxane based lubricants, such as in a laser printer. The formulation comprises 100 parts by weight natural rubber (e.g. electrosterically stabilized natural rubber graft and block terpolymer), and expressed as percentages by weight of the rubber the following components: about 5-35% (e.g. about 28%) acrylate monomer or monomers (such as methyl methacrylate, cyclohexyl methacrylate, benzyl methacrylate, and/or isobornyl methacrylate); about 0.5-8% acrylic acid and/or about 1-10% 4-acetoxystyrene; about 0-20% ethyl hexyl acrylate; about 1-50% (e.g.
