Polymer-ceramic mixed matrix compositions contain one or more organic polymers and a nano-sized dispersion of inorganic metal oxide particles which are dispersed throughout the composition. Materials have use in making membranes that act as transfer agents.

Hydrophilic cross-linked polymeric membranes, when prepared according to the process of the present invention, are unique in character in as much as the steady state permeability of the membrane has been altered by blending and cross-linking polyalkyl amines and polyalcohols. To obtain desired results, the compositions must contain at least 10% polyalkyl amines, with preferred amounts of polyalkyl amines in the composition being in excess of 40%, with over 50% polyalkyl amine concentration by weight.

The preparation and usefulness of polymer-ceramic mixed matrix composite materials comprising one or more organic polymers and a nano sized dispersion of inorganic metal oxide particles throughout the polymer(s) are described. The mixed matrix materials are used as mass transfer agents by fabricating the matrix materials into thin membranes and using them to dehydrate organic streams by pervaporation/vapor permeation separation processes. In addition, mixed matrix gels of similar composition are prepared in a variety of shapes and show a remarkable degree of reversible water absorbing properties. Mechanical and physical properties of the gels, such as extent of swelling in water, can be controlled by controlling the mixed matrix material composition.

This disclosure relates to a method and a system for processing grapes. An example system includes a simulated moving bed (SMB) device configured to receive a feed stream and an eluent stream as inputs and provide an extract stream and a raffinate stream as outputs. The feed stream includes a grape juice, the extract stream includes a high-sugar grape juice, and the raffinate stream includes a low-sugar grape juice. The system also includes fermentation equipment configured to produce a low-alcohol wine from the low-sugar grape juice.
