The improved method comprises forming a reaction mixture containing one or more sources of alkali metal oxide, organic nitrogen-containing cations, hydrogen ions, an oxide of silicon, water, and optionally, an oxide of aluminum, wherein the mole ratio for hydroxide ions/silica in said reaction mixture is zero and the mole ratio of H.sup.+ (additional)/silica in said reaction is between 0 and 1.0, and wherein the pH of said reaction mixture is at least about 7, and maintaining the reaction mixture at a temperature and pressure for a time necessary to crystallize therefrom said crystalline zeolite. Improvement in the present synthesis method resides, for example, in reduced crystallization time and reduced organic nitrogen-containing cation source requirement.

Abstract: Disclosed is a method of producing viscous hydrocarbons from a viscous petroleum-containing subsurface formation. At least an injection well and a production well are provided to extend from the surface of the earth into the subsurface formations. A high mobility, brine-filled channel is established through the lower portion of the subsurface formation to communicate with the injection and production well. After the high mobility channel is established, a solvent for the petroleum is injected into the high mobility channel. The injection of the solvent is continued until breakthrough of the solvent at the production well and thereafter until the ratio of petroleum to solvent produced from the production well becomes unfavorable. Thereafter, gas is injected into the high mobility channel to displace the solvent and petroleum from the formation to the production well.

Abstract: A novel system for producing film by extruding and/or casting at least two layers of resin, such as polyacrylonitrile homopolymer or interpolymers. The system provides for co-extruding a continuous multi-layer film with contiguous or tandem dies from a first supply of homogeneous resin solution and a second supply of non-homogeneous redissolved resin scrap. The film may be cast onto a smooth cooled drum surface to form substantially continuous adjacent layers from two or more resin supplies. By stripping the film from the drum as a continuous film strip and stretching the film an oriented structure is provided. Scrap resin, such as selvage trimmed from the stretched film or mill scrap, is comminuted and redissolved in solvent for recycle to the second supply of the extrusion step. The homogeneous layer prevents film disruption by inhomogeneities present in the contiguous layer containing redissolved scrap, which might cause localized stresses in the film and discontinuities during stretching.
