The conversion of nootkatol to nootkatene in a terpene blend is intentionally caused by adding a catalytically effective amount of at least one compound that catalyzes the reaction of nootkatol to nootkatene to the terpene blend containing nootkatol. Methods of preparing terpene blends, terpene blends, flavour compositions containing the terpene blends, beverages and foodstuffs containing the flavour compositions, fragrance compositions containing the terpene blends, and fragranced products containing the fragrance composition are also disclosed.

Provided are: a catalyst that is used in a reaction for producing hydrogen from an alkane without emitting CO.sub.2; a method of producing hydrogen without emitting CO.sub.2 by using the catalyst; and a method of producing ammonia using, as a reducing agent, hydrogen produced using the catalyst. The alkane dehydrogenation catalyst according to the present disclosure contains a graphene having at least one type of structure selected from an atomic vacancy structure, a singly hydrogenated vacancy structure, a doubly hydrogenated vacancy structure, a triply hydrogenated vacancy structure, and a nitrogen-substituted vacancy structure. The graphene preferably has from 2 to 200 of the structure approximately per 100 nm.sup.2 of the atomic film of the graphene. In addition, the hydrogen production method according to the present disclosure includes extracting hydrogen from an alkane by using the alkane dehydrogenation catalyst.

A method for preparing a supported carbon catalyst, the method includes at least the following steps: contacting a gas containing an organic silicon source with a silicon oxide-based material to obtain a precursor; contacting the precursor with a gas containing an organic carbon source to obtain the supported carbon catalyst. The temperature and energy consumption of the chemical vapor deposition of heteroatom-containing carbon material on silica-based materials can be greatly reduced in this method, and the cost of the catalyst can be effectively reduced.

The present disclosure provides a series of new and improved porous polyamide aerogels derived from multifunctional aromatics that combine the high mechanical strength of aramids with the pore structure of aerogels. The polyamide aerogels have a hyperbranched structure, relatively low density, high porosity and may be derived from functionalized monomers having more aromatic groups than functional groups. The present disclosure also provides a new method for producing the porous polyamide aerogels by polymerizing an aromatic multifunctional carboxylic acid or a ferrocene multifunctional carboxylic acid with a polyfunctional aromatic isocyanate at moderate reaction conditions followed by drying with liquid CO.sub.2. Also disclosed are various methods of use of these polyamide aerogels in a variety of applications, particularly in the generation of various precious metal catalysts. Thus, monolithic nanoporous carbon-supported Fe, Au, Pt, Pd, Co, Ni, Ru, and Rh catalysts are disclosed herein, which are derived by pyrolysis and transmetalation via galvanic replacement of ferrocene-based polyamide aerogels.
