Abstract: This invention is directed to a heat exchanged membrane reactor for electric power generation. More specifically, the invention comprises a membrane reactor system that employs catalytic or thermal steam reforming and a water gas shift reaction on one side of the membrane, and hydrogen combustion on the other side of the membrane. Heat of combustion is exchanged through the membrane to heat the hydrocarbon fuel and provide heat for the reforming reaction. In one embodiment, the hydrogen is combusted with compressed air to power a turbine to produce electricity. A carbon dioxide product stream is produced in inherently separated form and at pressure to facilitate injection of the CO2 into a well for the purpose of sequestering carbon from the earth's atmosphere.

Abstract: A high quality optical disc with extremely tiny bubbles or bubble less present in both disc-shaped substrates when they are laminated by means of an adhesive sheet in a operation process. The method includes bonding the adhesive agent to the surface of the lower disc-shaped substrate placing the upper disc-shaped substrate on the adhesive applied to lower disc-shaped substrate, pressurizing the upper disc-shaped substrate against the lower disc-shaped substrate by means of the pressing body, and exposing both the disk-shaped substrates to a high-pressure atmosphere. In a next operation process in which both the disc-shaped substrates are left to the inside of a high pressure atmosphere, firstly pressing body is permitted to press against the disc-shaped substrates to so enlarge or magnify the contact portion from the center side to the outside to render high-pressure atmospheric.

Abstract: A manufacturing method of metal substrate catalytic converter and the resulting product. In this method, a multiple layer aluminum and ferritic stainless steel composite material is first made by roll-bonding and then further processed to a final foil thickness. The composite foils are then fabricated to a honeycomb-like converter with air flow channels. The converter is then thermally treated at a high temperature during a necessary converter fabrication process. The monolithic FeCrAl alloy is then obtained in the converter by in-situ diffusion alloying with pre-oxide film on the surfaces. The resulted material has improved oxidation resistance and thermal dimension stability at a high temperature.
