An assembly and method for gas analysis. The assembly comprises a catalyst compartment for catalytically reacting a component of a gas sample, producing one or more gas species as products. A product compartment receives the gas species, and a sensing element within the compartment senses the amount of one or more of the gas species. This amount is compared to the amount of the same gas species present in a reference compartment containing a non-catalyzed gas sample, providing the amount of the gas species produced by catalysis. Using this value, the content of the gas component in the gas sample is calculated based upon the stoichiometry of the catalyzed reaction. In preferred embodiments, the gas for analysis is a process gas for fuel production, and the catalyst is a high temperature shift catalyst that catalyzes the reaction of carbon monoxide and water into hydrogen and carbon dioxide.

A method and apparatus for converting carbonaceous material to a stream of carbon rich gas, comprising heating a slurry feed containing the carbonaceous material in a hydrogasification process using hydrogen and steam, at a temperature and pressure sufficient to generate a methane and carbon monoxide rich stream in which the conversion time in the process is between 5 and 45 seconds. In particular embodiments, the slurry feed containing the carbonaceous material is fed, along with hydrogen, to a kiln type reactor before being fed to the fluidized bed reactor. Apparatus is provided comprising a kiln type reactor, a slurry pump connected to an input of the kiln type reactor, means for connecting a source of hydrogen to an input of the kiln type reactor; a fluidized bed reactor connected to receive output of the kiln type reactor for processing at a fluidizing zone, and a source of steam and a source of hydrogen connected to the fluidized bed reactor below the fluidizing zone. Optionally, a grinder can be provided in the kiln type reactor.

Disclosed are systems and methods for adjustment of muscles, tendons and ligaments comprising a main tool and a secondary tool. The main tool comprises a handle and a striking portion. The secondary tool comprises a receiving portion and a target area contact portion. The target area contact portion is placed on a target area of a patient and the striking portion is used to strike to the receiving portion with sufficient force to properly adjust the target area.
