Abstract: The instant invention pertains to new processes which produce an energy source effectively, efficiently, and in a more environmentally friendly manner. The process comprises hydrolyzing a lignocellulosic feedstock to form lignocellulosic hydrolyzate and a hydrolyzate residue. The lignocellulosic hydrolyzate is treated to produce hydrogen. The hydrolyzate residue may be reacted with hydrogen in the presence of a catalyst to yield the energy source.

Abstract: The present invention provides a method and apparatus for identifying an activation of a burst disk. A pressure data or a temperature data relating to a flow is received. A determination is made whether the flow is interrupted based upon the at least one of the pressure data and the temperature data. A burst disk activation is identified in response to determining that the flow is interrupted.

Abstract: The method of protecting a surface in a gasifier which is normally an exposed surface in the gasifier. The method includes forming a refractory attachment with a securement surface that confronts the protectable surface in the gasifier and mechanically securing the refractory attachment onto the protectable surface in the gasifier without the refractory attachment penetrating the protectable surface. Such mechanical securing is achieved by providing a latch which if formed of complementary shapes of the securement surface and the protectable surface.
