Catalytic steam gasification process with recovery and recycle of alkali metal compounds

A high efficiency gasification process for converting carbonaceous solids to methane and apparatus for its practice are described. The process includes reacting steam and carbonaceous solids comprising ash in the presence of alkali metal catalyst in a gasification reactor to produce combustible gases and char particles comprising ash and alkali metal catalyst constituents, treating a stream of such char particles in an alkali metal catalyst recovery system to recover the catalyst constituents as alkali metal compounds, and recycling such recovered compounds. Within the alkali metal catalyst recovery system the process includes quenching the stream of char particles with water whereby such particles are cooled and fractured, dissolving soluble alkali metal catalyst constituents from the fractured solids to form a first alkali metal catalyst solution and washed solids, optionally reacting the washed solids in alkaline solution to form a second alkali metal catalyst solution, upgrading said first and optional second alkali solution to recover the alkali metal catalyst constituents as said alkali metal compounds.

Retraction arm to extract a mezzanine circuit board connector from a motherboard connector

An information handling system mezzanine circuit board disposed in a parallel configuration over a motherboard is selectively coupled and de-coupled at the motherboard with a retraction and latching device that translates retraction force applied at an accessible actuation portion to push upward from below the mezzanine circuit board. A retraction portion of the retraction and latching device provides an upward force at the bottom surface of the mezzanine circuit board to separate the mezzanine circuit board connector from the motherboard connector so that an end user can lift the mezzanine circuit board away from the motherboard.

Pneumatic lifting system and method

A lifting device and method therefore utilizing an air bag or the like for lifting an object supported by a wheeled platform or the like, from a stationary, parked configuration wherein the object conceals the wheeled platform and supports the object, to a lifted, configuration whereby the wheeled platform supports the object, allowing same to be easily moved via the wheeled platform. The preferred embodiment of the present invention contemplates a planter unit comprising a pot or the like for containing a plant, said pot having a false bottom wherein there is situated a support platform having castors or the like thereon, and an air bag or other flexible container configured to be filled with fluid situated between the wheeled platform and the underside of the pot. In use, the false bottom has a cavity formed therein to enclose the wheeled platform, the false bottom having a lower edge supporting the pot when the air bag is uninflated. To lift the pot and raise the lower edge of the false bottom from the floor, the air bag or the like is filled with air via a hand pump or compressed air source, which expands the bag so as to lift the planter such that the wheeled support then supports the planter. The walls forming the false bottom surround the air bag in its inflated condition, stabilizing the unit so that it may be wheeled to its desired location, and preventing “rolling” of the airbag and planter from the platform.

Tar-free gasification system and process

A novel tar-free gasification process and system is disclosed that involves the partial combustion of recycled dry solids and the drying of a slurry feedstock comprising carbonaceous material in two separate reactor zones in a two stage gasifier, thereby producing mixture products comprising synthesis gas. The synthesis gas produced from the high temperature first stage reaction zone is then quenched in the second stage reaction zone of the gasifier prior to introduction of a slurry feedstock. The temperature of the final syngas exiting the second stage reaction zone of the gasifier is thereby moderated to be in the range of about 350-900° F., which is below the temperature range at which tar is readily formed, depending upon the type of carbonaceous feedstock utilized.
