摘要:
The present invention provides a process and apparatus for the gasification of a liquid fuel and includes providing a supply of a liquid fuel, a supply of oxidant, and a supply of liquid water; atomizing the liquid fuel and mixing it with the oxidant and steam; catalytically reacting the fuel-oxidant-steam mixture in a catalyst bed; initiating the catalytic reaction with an ignition source; positioning a heat exchanger in proximity with the catalyst bed so as to convert the liquid water to steam; and feeding the steam into the catalytic reaction, thereby eliminating the need for a liquid fuel vaporizer. A preferred catalyst bed includes an ultra-short-channel-length metal substrate.
摘要:
A method is provided for controlling the operating temperature of a catalytic reactor using a closed-loop system that provides for varying the reactor input and other operating parameters in order to maintain the operating temperature of the reactor at or near the initial setpoint temperature for operation of the reactor. In one example, maximum and minimum operating temperatures with a catalytic partial oxidation reactor are controlled, as well as maintaining control over the corresponding minimum required ratio of oxygen atoms to carbon atoms, such that the operating temperature within the reactor is maintained below the material limits but above threshold temperatures for coking.
摘要:
There is provided a process for converting methane to hydrocarbons having at least two carbon atoms (i.e. higher hydrocarbons). The process involves oxidizing methane with a metal sulfide oxidizing agent. After this conversion of methane, the reduced metal sulfide may be regenerated by oxidation of the reduced metal sulfide.
摘要:
There is provided a catalyst and a process for the direct partial oxidation of methane with oxygen, whereby hydrocarbons having at least two carbon atoms are produced. The catalyst used in this reaction is a spinel oxide, such as MgMn.sub.2 O.sub.4 or CaMn.sub.2 O.sub.4, modified with an alkali metal, such as Li or Na.

摘要:
There is provided a process for converting methane to hydrocarbons having at least two carbon atoms. The process involves contacting methane with an oxidizing agent, such as oxygen, at a relatively moderate temperature of less than about 700.degree. C. and a relatively high pressure of greater than about 20 atmospheres.

There is provided a process for the direct partial oxidation of methane with oxygen, whereby organic compounds comprising higher hydrocarbons are produced. The catalyst used in this reaction is an NiZSM-5 catalyst. This catalyst may be prepared by ion exchanging or impregnating a ZSM-5 catalyst with a suitable nickel salt such as nickel nitrate.

There is provided a process for the direct partial oxidation of methane with oxygen, whereby hydrocarbons having at least two carbon atoms are produced. The catalyst used in this reaction is a cadmium-manganese oxide catalyst.
摘要:
A paraffin conversion process for hydroisomerizing a nitrogen and wax-containing hydrocarbon feedstock comprising contacting the feedstock with a catalyst including a ZSM-11 zeolite characterized by an alpha value from about 10 to 50, in combination with a Group VIII metal hydrogenation-dehydrogenation component of platinum or palladium at a temperature of about 400.degree. F. to about 850.degree. F. and at a pressure of from about 200 to about 2000 psig.
摘要:
A combustion enhancing catalyst is deposited on a particulate refractory substrate such as sand. The solid fuel is contacted with the impregnated substrate and burned, for example, in a fluidized bed combustor. The substrate and catalyst remains in the combustor thereby obviating problems of catalyst loss and adverse effects of emitted metal particles.
