Abstract: An improved storage system, with a mechanism for easily mounting and detaching containers has been developed. The mounting mechanism consists of mounting rods attached to a storage container, which engage in suitably-shaped slots in hangers that can be attached to an overhead structure. The hangers can either be attached to the inside faces of adjacent joists or mounted to an overhead surface. The mounting mechanism is simple in construction and allows easy and rapid mounting and detaching of the storage container. The storage system results in a user-friendly and economical, overhead storage container that can easily be installed with simple hand tools.

Abstract: A method for esterification of free fatty acids with methanol. The method has steps of: (a) contacting a heterogeneous esterification catalyst in a reactor with a reaction mixture containing: (i) methanol and (ii) a triglyceride mixture containing 70-99.8 wt % triglycerides and 0.2-30 wt % free fatty acids, under conditions suitable for esterification, to produce a product stream; (b) separating water and methanol from the product stream to produce a dried product stream; (c) contacting the dried product stream with methanol to produce a methanol-rich phase and a triglyceride-rich phase; and (d) separating the methanol-rich phase and recycling it to the reactor.

Abstract: A continuous process for esterification of fatty acids in glyceryl esters with C1-C8 aliphatic alcohols in a tubular reactor. The method uses an expanded resin catalyst bed in the tubular reactor.

Abstract: A method for purification of crude triglycerides to be used as a raw material for production of biodiesel fuel. Crude triglycerides are contacted with a variety of adsorbents and ion exchange resins to reduce the levels of impurities.

Abstract: A method for purification of crude glycerol, especially crude glycerol derived from biodiesel production using alkaline catalysts. The method comprises combining the crude glycerol with acid, separating a glycerol layer, and treating the glycerol layer to decolorize it.

Abstract: This invention discloses a process for producing a high Viscosity Index lubricant having a VI of at least 125 from a waxy hydrocarbon feed having a wax content of at least 40 wt %. The process comprises catalytically dewaxing waxy paraffins present in the feed by isomerization in the presence of hydrogen and in the presence of a low acidity large pore zeolite isomerization catalyst. This catalyst has a ratio of SiO.sub.2 /Al.sub.2 O.sub.3, as synthesized, of at least 50:1, and an alpha value of not greater than 20, wherein the catalyst is prepared in the absence of boron. The catalyst further comprises a noble metal hydrogenation component. The feed may be hydrocracked prior to dewaxing with the large pore zeolite. The feed may be solvent dewaxed prior to isomerization. The effluent of the isomerization step may also be further dewaxed by either solvent or catalytic means in order to achieve target pour point.
