A hydrogenation catalyst with a small amount of supported metal that is excellent in stability and inhibition of side reactions is provided. The catalyst hydrogenates an aromatic hydrocarbon compound into an alicyclic hydrocarbon compound, and a Group X metal represented by nickel is supported in a composite support including at least alumina and titania. The composite support preferably includes at least an alumina substrate coated with titania. It is also preferable that the Group X metal is prereduced by hydrogen. In the case that the Group X metal is nickel, the nickel content is preferably 5-35 wt % as nickel oxide in the catalyst. The substrate includes, for example, a porous structure formed by a plurality of needle-shaped or column-shaped intertwined three-dimensionally.

An iodide compound is adsorbed and removed from an organic acid containing the iodide compound as an impurity by passing the organic acid through a packed bed of a cation-exchange resin having silver ion carried thereon at 50&#xb0; C. or lower. The cation-exchange resin is a macroporous-type resin with an average particle size of 0.3 to 0.6 mm and an average pore size of 15 to 28 nm, and silver ion substitutes for 40 to 60% of the active site.

Method for removing iodide compound from organic acid

A process for the production of a carbonic diester, wherein an alcohol is reacted in a reaction zone with carbon monoxide and oxygen in the presence of (a) metallic copper or a copper compound, (b) a heterocyclic compound containing one or more nitrogen atoms in the cyclic skeleton and (c) a glycol ether represented by the following formula (I):

Transesterification involving a fat, or a fat and fatty acid, or a phospholipid is carried out with a lipase or phospholipase immobilized on a polymer carrier. The transesterification is preferably carried out in a system containing a very small amount of water such as 50 to 2,000 ppm. The phospholipase can be phospholipase A.sub.2. In a first embodiment, lipase from a microorganism of the genus Rhizopus, Mucor, Alcaligenes or Candida is immobilized on the surface of a hydrophobic, insoluble organic polymer carrier having pores of an average diameter of 10 nm or larger and having on the surface epoxy groups capable of covalently binding lipase. The immobilized lipase is dried under reduced pressure. In a second embodiment, lipase is immobilized on the surface of a polymer carrier such as a hydrophobic, insoluble organic polymer carrier having a pore diameter of 5 to 1,000 nm and having on the surface a functional group capable of binding lipase and an anion-exchange group. Preferably, the functional group is an epoxy group and the anion-exchange group is a tertiary amino group. The lipase may be obtained from the same microorganism as in the first embodiment or from another lipase-producing microorganism. Iramobilization can be carried out as in the first embodiment. It is preferred to contact a solution of lipase with the polymer carrier in the presence of a fatty acid or derivative thereof for 10 minutes to 10 hours to covalently bond the lipase to the polymer carrier.

An immobilized lipase is prepared for transesterification of oils, fats or phospholipids in a reaction system containing a very small amount of water such as 50 to 2,000 ppm. The lipase may be a phospholipase such as phospholipase A.sub.2. In a first embodiment, lipase from a microorganism of the genus Rhizopus, Mucor, Alcaligenes or Candida is immobilized on the surface of a hydrophobic, insoluble organic polymer carrier having pores of an average diameter of 10 nm or larger. A solution of lipase is contacted with the polymer carrier for 10 minutes to 40 hours to covalently bond the lipase to the carrier. The immobilized lipase is dried under reduced pressure to a water content of 0.5 to 30 wt %. In a second embodiment, lipase is immobilized on the surface of a polymer carrier such as a hydrophobic, insoluble organic polymer carrier having a pore diameter of 5 to 1,000 nm and having a functional group capable of binding lipase in a aqueous solution and an anion-exchange group on the surface. Preferably, the functional group is an epoxy group and the anion-exchange group is a tertiary amino group. The lipase may be obtained from the same microorganism as in the first embodiment or from another lipase-producing microorganism. Immobilization can be carried out as in the first embodiment.

A protein-rich composition of brewer's spent grain origin is disclosed, which includes products separated from the husks of BSG and which contains 40 to 60% by weight of proteins, 12 to 18% by weight of lipids, 2 to 6% by weight of fibrous materials, and 1 to 4% by weight of ashes based on dry weight.

Protein-rich products of brewer's spent grain origin

A process for producing a protein-rich product and/or a fibrous product is disclosed which includes the steps of pressing brewer's spent grain (BSG) in a wet state, and sieving the resulting pressed BSG in the presence of water to thereby separate it into a protein-containing fraction and a fibrous fraction.

A method for positioning and supporting a tree having a tree stem and a rootball is disclosed wherein a hole is formed in a ground surface. Anchors are positioned within the hole. Block fragments are positioned around the tree stem. A securing member is disposed around the block fragments and the tree stem for securing the block fragments to the tree stem. The rootball is positioned within the hole. A tension member is connected to the securing member and the anchors. A tightening member is connected to the tension member for adjusting the tension of the tension member for retaining and tree within the hole. Thereafter, the rootball positioned within the hole is buried.
