In a method, device, catalyst and a method for producing a catalyst for the catalytic conversion of a substance mixture containing glycerol to propanol in a fixed-bed reactor, substrates of the catalyst have inorganic materials and/or metal oxides. The substrates have a pore diameter at the surface of between 10 and 25 angstroms, preferably between 12 and 20 angstroms, particularly preferably 15 angstroms.

The invention pertains to a device for determination of a catalyst state in a chemical reactor and to a method for detecting a catalyst state under in situ reaction conditions. A reactor is provided with a solid catalyst provided in a reactor chamber. A fluid sample is taken from the reactor chamber and is transferred to a sample chamber. The temperature at the extraction site of the sample in the reactor chamber is determined and the temperature of the sample chamber is adjusted to the same temperature. A small amount of the catalyst provided in reactor chamber is provided in sample chamber and is contacted with the sample flow. Spectroscopic information is then obtained on the catalyst provided in sample cell, e.g. by an IR spectrometer.

A method 10 for processing hydrocarbons for recycling includes the steps of: a) heating solid and/or liquid hydrocarbons in a chamber 16 in the absence of air, to convert at least some of the hydrocarbons into hydrocarbon gas; b) reacting the hydrocarbon gas in a reactor 20 or conduit with a catalyst 22 including a transition metal or transition metal salt, and a carbide, to break the hydrocarbon gas down into hydrocarbon products; and c) collecting the hydrocarbon products or conveying the hydrocarbon products elsewhere for use.

A source material gas (31) is supplied to a catalyst (30), a first heating medium (21) is caused to flow through a first heat exchange section (22) so that a temperature of a surface of the first heat exchange section (22) on a catalyst side is maintained higher than a dew point of a reacted gas (32), a second heating medium (51) is caused to flow through a second heat exchange section (52) so that a temperature of a surface of the second heat exchange section (52) on a space (4) side is maintained not higher than the dew point of the reacted gas (32), and a liquid obtained by condensation in the space (4) is allowed to fall down so as to be separated from the source material gas.

An inerting system includes a fluid circuit, a reactor within the fluid circuit, at least one particulate removal device (PRD) downstream from the reactor, and a fluid tank. The fluid tank is downstream from the at least one PRD. A method for removing particulates from a fluid stream in a fluid circuit includes receiving a fluid stream in a reactor within a fluid circuit, outputting an exhaust stream from the reactor, receiving the exhaust stream in at least one PRD downstream from the reactor, removing particulate from the exhaust stream, and receiving the exhaust stream with particulate removed in a fluid tank downstream from the at least one PRD.

Devices and methods for reducing the specific energy required to reform or pyrolyze reactants in plasmas operating at high flow rates and high pressures are presented. These systems and methods include 1) introducing electrons and/or easily ionized materials to a plasma reactor, 2) increasing turbulence and swirl velocity of the flows of feed gases to have improved mixing in a plasma reactor, and 3) reducing slippage from a plasma reactor system. Such plasma systems may allow plasma reactors to operate at lower temperatures, higher pressure, with improved plasma ignition, increased throughput and improved energy efficiency. In preferred embodiments, the plasma reactors are used to produce hydrogen and carbon monoxide, hydrogen and carbon, or carbon monoxide through reforming and pyrolysis reactions. Preferred feedstocks include methane, carbon dioxide, and other hydrocarbons.
