摘要:
Methods and apparatuses are provided for removing odorants, such as tetrahydrothiophene, and sulfur compounds, such as hydrogen sulfide, out of a gas, such as natural gas. Such systems are typically required by fuel processor systems, where the odorant and sulfur compounds might, otherwise, poison the fuel processor and fuel cell catalysts. Systems (500) of the present invention are based on the use of two filtration stages (506, 508) so that the odorant removal function is segregated from the general removal of hydrogen sulfide.

The aim of the invention is to improve the efficiency of an axial-piston motor comprising at least one working cylinder fed by a continuously operating combustion chamber comprising a pre-combustion chamber and a main combustion chamber. To this end, the axial-piston motor is provided with a pre-combustion chamber comprising a check valve.
摘要:
A flameless combustion heater system is described that comprises a flameless combustion heater; an oxidant inlet pipe; a fuel inlet pipe; and a preheater for preheating the oxidant or the fuel, said preheater comprising an oxidation catalyst. A method for starting up a flameless combustion heater is described comprising passing a fuel-oxidant mixture to a preheater comprising an oxidation catalyst to preheat the fuel or oxidant stream being fed to the heater. A method for controlling the temperature of the flameless combustion heater system is also described that comprises controlling the amount of fuel and/or oxidant that passes through the preheater.
摘要:
This invention generally refers to a new generation of fuel additives which can provide catalytic action to improve the combustion process of fossil fuels and to a catalyst among others containing an iron compound combined with an over-based magnesium compound with molecular size particles inside the combustion chamber. Such fuel additive catalysts are particularly useful for fuel oil combustion, natural gas combustion, stationary gas turbines, natural gas-fired reciprocating engines, diesel engines, gasoline engines and all stationary dual-fuel engines.

摘要:
The invention provides a metal alloy fuel catalyst for decontaminating a hydrocarbon fuel, including diesel and bio-diesel fuel, of a bacterial contamination. The metal alloy fuel catalysts preferably includes about 70% Sn, about 22% Sb, about 4% Bi, and about 4% Pb, although other formulations are possible. The fuel catalyst can take the form of an in-line component in a fuel system or be coated within a fuel storage container.
摘要:
An improved diesel operation system employs a lightly diesel oxidation catalyst (DOC), preferably with a platinum containing fuel borne catalyst (FBC) in the fuel. The DOC is at least partially lightly catalyzed with precious metal catalyst, e.g., platinum group metal, having a metal loading of from about 3 to 15 grams per cubic foot to minimize formation Of NO 2 in the exhaust gas. Preferred fuel borne catalyst levels will be low, e.g., from 0.05 to 0.5 ppm for platinum and 3 to 8 ppm for cerium and/or iron, thereby providing effective engine out emissions reductions without discharging excessive amounts of metal catalysts or NO 2 to the atmosphere.
