A method of producing bifunctional catalyst systems that include a carbon-coated metal catalyst may comprise: coating a metal catalyst particle with a carbon-containing small molecule to produce a coated metal catalyst particle; carbonizing the carbon-containing small molecule on the coated metal catalyst particle to produce a carbon-coated metal catalyst particle; and mixing the carbon-coated metal catalyst particle with an acid catalyst particle to produce an acid/metal bifunctional catalyst system. Further, a method of producing bifunctional catalyst systems that include a carbon-coated acid catalyst may be similarly performed by coating a metal catalyst particle with a carbon-containing small molecule to produce a coated metal catalyst particle; carbonizing the carbon-containing small molecule on the coated metal catalyst particle to produce a carbon-coated metal catalyst particle; and mixing the carbon-coated metal catalyst particle with an acid catalyst particle to produce an acid/metal bifunctional catalyst system.

[Problem] It is an object of the present invention to provide a method for collecting seawater that contains plankton and producing DHMBA, which is an antioxidant, from the plankton contained in the seawater.

[Solution] The method of the present invention includes: filtering collected seawater containing the plankton using a filter; taking out a cell content from the plankton remaining on the filter; subsequently heating/pressurizing the cell content taken out; and producing 3,5-dihydroxy-4-miethoxybenzyl alcohol from the heated/pressurized product. The plankton is a diatom. [Selected Drawing] FIG. 1

A method for preparing a carbonaceous product includes providing oxygen, in particular from electrolysis, and providing a fuel. The method also includes combusting the fuel with the oxygen by an oxy-fuel combustion process in order to provide energy, purifying a flue gas produced by the oxy-fuel combustion process, and separating carbon dioxide from the flue gas produced by the oxy-fuel combustion process, wherein energy provided by the oxy-fuel combustion process includes, in particular exclusively, heat which is used as process heat for purifying and/or for synthesising or providing the carbonaceous product. A corresponding system is designed to carry out the described method.

The present invention relates to a high pressure process for Pre-Combustion and Post-Combustion CO.sub.2 capture (HP/MP/LP gasification) from a CO.sub.2 gas stream (CO2-Stream) by way of CO.sub.2 total subcritical condensation (CO2-CC), separation of liquid CO.sub.2, higher pressure elevation of obtained liquid CO.sub.2 via HP pump, superheating of CO.sub.2 up to high temperature for driving of a set of CO.sub.2 expander turbines for additional power generation (CO2-PG), EOR or sequestration (First new Thermodynamic Cycle). The obtained liquid CO.sub.2 above, will be pressurized at a higher pressure and blended with HP water obtaining high concentrated electrolyte, that is fed into HP low temperature electrochemical reactor (HPLTE-Syngas Generator) wherefrom the cathodic syngas and anodic oxygen will be performed. In particular the generated HP oxygen/syngas will be utilized for sequential combustion (“H.sub.2/O.sub.2-torches”) for super-efficient hydrogen based fossil power generation (Second new Thermodynamic Cycle).
