Abstract: A non-sticking lip tipping paper is disclosed that includes a base paper, a color layer and a surface coating. The color layer is formed by printing and drying a color ink on the base paper; the surface coating includes a water-based glue and is coated thereon after drying the color layer. The water-based glue includes the following components by weight: 30-65 parts of a modified water-based resin solution, 10-20 parts of water, 8-15 parts of ethanol, and 5-12 parts of a water-based additive. The water-based additive is a mixture of a wax emulsion and magnesium silicate in a weight ratio of 1:5. A preparation method and a method of applying the non-sticking lip tipping paper are also disclosed.

Abstract: Disclosed herein is a process for separating components of a gas mixture using gas-separation copolymer membranes. These membranes use a selective layer made from copolymers of perfluorodioxolane monomers. The resulting membranes have superior selectivity performance for gas pairs of interest while maintaining fast gas permeance compared to membranes prepared using conventional perfluoropolymers, such as Teflon® AF, Hyflon® AD, and Cytop®.

Abstract: Disclosed herein is a methanol production process that includes at least two membrane separation steps. Using the process of the invention, the efficiency of methanol production from syngas is increased by reducing the compression requirements of the process and/or improving the methanol product yield. As an additional advantage, the first membrane separation step generates a hydrogen-rich stream which can be sent for other uses. An additional benefit is that the process of the invention may debottleneck existing methanol plants if more syngas or carbon dioxide is available, allowing for feed of imported carbon dioxide into the synthesis loop. This is a way of sequestering carbon dioxide.

Abstract: A membrane-based process for separating mixtures of target gases if the gas mixture also contains C3+ hydrocarbon vapors. The process uses gas-separation membranes having a base membrane and a coating layer. The base membrane incorporates a selective layer made from a polymer selective between the light gases to be separated. The coating layer comprises a fluorinated polymer capable of protecting the base membrane from C3+ hydrocarbon vapors and liquids.
