Abstract: An adsorbent for removal of impurities from silicone based solvents is presented. The adsorbent is regenerable for repeated use in cleaning silicone based solvents.

Abstract: A device is disclosed for the generation of hydrogen peroxide. The device produces hydrogen peroxide on an as-needed basis through the use of electrolysis of water, wherein the hydrogen and oxygen are mixed in the electrolyzer, and the hydrogen and oxygen mixture in water are reacted in a reactor to produce hydrogen peroxide.

Abstract: A process and apparatus is disclosed for contacting feed with mixed catalyst in a secondary reactor that is incorporated into an FCC reactor. The mixed catalyst used in the secondary reactor is regenerated catalyst from a regenerator that regenerates spent catalyst from an FCC reactor that is mixed with spent catalyst from either the FCC reactor or the secondary reactor. The mixing of spent and regenerated catalyst reduces the catalyst temperature and tempers catalyst activity to inhibit both thermal and catalytic cracking reactions.

Abstract: A solid fuel for use in fuel cells is presented. The solid fuel includes solid oxygenates, and mixtures for generating a gaseous fuel from the solid fuel. The solid fuel can be contained in a cartridge and reacted with a liquid reactant for generating a gaseous fuel used in the fuel cell.

Abstract: An distributor arrangement introduces spent FCC catalyst more uniformly across the dense bed of the regenerator to provide more even contact with regeneration gas in order to avoid hot spots and zones of incomplete combustion. The invention forms a fluidized hopper to collect spent catalyst and a horizontally extended header with multiple horizontally extended outlet arms to place catalyst into the regenerator. The invention may use an aeration means to fluidize the header to further assist catalyst flow. Furthermore, the spent catalyst delivered to the top of the regenerator dense reduces NOx emissions in the flue gas.

Abstract: A process for removing H2S and mercaptans from a hydrocarbon stream is disclosed. A hydrocarbon stream such as a LPG stream is contacted with a weakly basic stream, e.g., a sodium bicarbonate stream in order to extract the H2S and mercaptans from the hydrocarbon stream into the basic stream. The basic stream is now treated in a reactor containing a sulfide oxidizing microorganism in order to convert the H2S to sulfur and the mercaptans to disulfides. Finally, the sulfur and disulfides are separated from the basic aqueous stream which can be recycled and used to treat a fresh hydrocarbon stream. The treated hydrocarbon stream is purified to the point that it passes the copper strip test, while the purified basic stream contains less than 0.08 g/l of elemental sulfur.
