A flavour delivery system for tobacco includes a flavour material entrained in a zeolite material and forming a core and a wax material encapsulating the core.

Wax encapsulated zeolite flavour delivery system for tobacco

A process for producing polyolefin particles from a polyolefin composition, comprising the steps of: a) providing a melted composition of a polyolefin and b) providing particles from the melted composition by: b1) mixing a first flow of a supercritical fluid in the melted composition in a pressure vessel to obtain a solution saturated with the supercritical fluid and b2) passing the solution from the pressure vessel through a throttling device to a spraying tower to expand the solution to obtain the polyolefin particles in the spraying tower, wherein a second flow of a supercritical fluid is injected in the throttling device, wherein the supercritical fluid is a supercritical fluid of a substance selected from the group consisting of CO, NH, HO, NO, CH, ethane, propane, propylene, n-butane, i-butane, n-pentane, benzene, methanol, ethanol, isopropanol, isobutanol, chlorotrifluoromethane, monofluoromethane, 1,1,1,2-Tetrafluoroethane, toluene, pyridine, cyclohexane, cyclohexanol, o-xylene, dimethyl ether and SFand combinations thereof.

Process for the preparation of polyolefin particles

The present invention relates to a process for recycling polyolefin, comprising the steps of: 1) feeding a solid post-consumer polyolefin composition comprising polyolefin and contaminants and a flow of an extraction fluid to an extractor having a pressure of 100-1000 bar and a temperature of 20-80&#xb0; C. to obtain a solid extracted composition, 2) melting the solid extracted composition to obtain a melted composition, 3) providing particles from the melted composition by: 3a) mixing a flow of a supercritical fluid in the melted composition in a pressure vessel to obtain a solution saturated with the supercritical fluid and 3b) passing the solution from the pressure vessel through a throttling device to a spraying tower to expand the solution to obtain polyolefin particles in the spraying tower.

A smoking composition includes tobacco material and a flavor delivery system. The flavor delivery system includes a flavor material and first wax material forming a core and a second wax material encapsulating the core. The second wax material being a different wax material than the first wax material.

Wax encapsulated flavour delivery system for tobacco

A process for increasing purity of a low density polyethylene (LDPE) composition, comprising the steps of: a) providing a melted composition comprising LDPE having Mn of at least 5.0 kg/mol according to size exclusion chromatography, Mw of at least 50 kg/mol according to size exclusion chromatography, a density of 915 to 935 kg/maccording to ISO1183 and a melt flow rate of 0.10 g/10 min to 80 g/10 min according to ISO1133:2011 measured at 190&#xb0; C. and 2.16 kg, and b) providing particles from the melted composition by: b1) mixing a supercritical fluid in the melted composition to obtain a solution saturated with the supercritical fluid and b2) expanding the solution through an opening to obtain the particles.

Method for producing clean thermoplastic particles

The disclosed methods for preparing and isolating carboxylic esters ensure a high product purity and minimize technical complexity. These methods are based on the reaction of a carboxylic acid with an alcohol in an aqueous medium. In some examples, the alcohol is used both for the esterification and for the precipitation of the salts, preferably ammonium salts, formed in the synthesis.
