摘要:
By controlling the pre-treatment of biomass materials and pyrolysis conditions, silica samples with various surface areas and levels of crystallinity were synthesized. With proper treatment, biogenic silica nanoaggregate (25-30 nm in diameter) can be synthesized from biomass materials. The characterizations revealed that the silica nanoaggregates were composed of smaller primary silica nanoparticles (ca. 4.2 nm in diameter). Under controlled melting catalyzed by metal salt cations, the silica nanoaggregates may be fuse to form semi-crystalline porous silica frameworks with tunable pore size and structural integrity. Organosilicon complexes were synthesized from the bio derived silica nanoaggregates.
摘要:
The disclosure provides an LS methane hydrate containing a plurality of methane hydrate crystals and lignosulfonate. The disclosure also provides a method of making an LS methane hydrate by combining methane gas, liquid or solid water, and LS at controlled temperature and starting pressure for a time sufficient to form LS methane hydrate. The disclosure further provides a method of producing energy from an LS methane hydrate by providing an LS methane hydrate directly to a combustion chamber, whereby methane in the methane hydrate and LS are converted to energy in the combustion chamber and water in the methane hydrate is converted to steam. The disclosure additionally provides a method of releasing methane from an LS methane hydrate by heating an LS methane hydrate.

摘要:
This invention relates to a gas hydrate (often referred to as a clathrate) comprising a water-in-gas emulsion (egdry-water (DW)) and an enclathrated exogenous gas such as for example methane, natural gas, hydrogen or carbon dioxide.
