COMMENT PRODUIRE DES ESSENCES SYNTHETIQUES OU DES DIESELS SYNTHETIQUES EN N'UTILISANT QUE DU GAZ NATURAL COMME MATIERE BRUTE

HOW TO PRODUCE SYNTHETIC GASOLINES OR SYNTHETIC DIESELS USING ONLY NATURAL GAS AS RAW MATERIAL

Abrégé français

Mon procédé ne convertit pas le gaz naturel en gaz naturel comprimé, ne convertit pas le gaz naturel en gaz naturel liquéfié, mais fait appel à deux nouvelles équations chimiques permettant de convertir le gaz naturel en essences synthétiques ou en diesels synthétiques. Après production de CO grâce à une technique de combustion partielle, mon procédé améliore le procédé Fischer- Tropsch, cela en remplaçant le H2 par du CH4, suivant deux nouvelles équations chimiques, et en ajoutant du sel (NaCl) à un catalyseur à base de fer (FeO) ou à n'importe quel autre catalyseur capable de générer des hydrocarbures. Au lieu de produire une vaste gamme d'hydrocarbures synthétiques comme le font les autres procédés, le mien ne génère que des essences synthétiques selon l'équation 5 CH4 + 2 CO = C7H16 + 2 H2O, ou que des diesels synthétiques selon l'équation 11CH4 + 5 CO = C16H34 + 5 H2O, cela grâce à l'addition de sel à un catalyseur à base de fer ou à n'importe quel autre catalyseur. Nul raffinage n'est nécessaire. Comme le gaz naturel est l'hydrocarbure le plus propre, mon procédé permet de produire des essences ou des diesels synthétiques propres. Comme le prix du gaz naturel est très faible, mon procédé permet de produire des essences ou des diesels synthétiques propres à très faible coût.

Abrégé anglais

My process does not convert natural gas into compressed natural gas, does not convert natural gas into liquified natural gas but uses 2 new chemical formulas to convert natural gas into synthetic gasolines or into synthetic diesels. After producing CO through a technology of partial combustion, my process improves Fischer Tropsch process using CH4 instead of H2, following 2 new chemical equations and adding salt (NaCl) to an iron (FeO) catalyst or to any other catalyst capable of generating hydrocarbons. Instead of producing a large variety of synthetic hydrocarbons like other processes do, my process delivers only synthetic gasolines following 5 CH4 + 2 CO = C7H16 + 2 H2O or only synthetic diesels following 11CH4 + 5 CO = C16H34 + 5 H2O thanks to the addition of salt to an iron catalyst or to any other catalyst. No oil refining needed. Because natural gas is the cleanest hydrocarbon, my process produces clean synthetic gasolines or clean synthetic diesels. Because the prices of natural gas are very low, my process produces clean synthetic gasolines or clean synthetic diesels at very low costs.

HOW TO PRODUCE SYNTHETIC GASOLINES OR SYNTHETIC DIESELS USING ONLY NATURAL
GAS AS RAW MATERIAL.
FIELD OF THE INVENTION
The present invention is directed to a process for producing synthetic
hydrocarbons
from methane, in particular, to a process for producing synthetic gasolines or
synthetic
diesels from methane through catalytic hydrogenation.
BACKGROUND OF THE INVENTION
Converting carbon monoxide into synthetic hydrocarbon through catalytic
hydrogenation is a
process invented by Mr. Fischer and Mr. Tropsch in 1925. Fischer-Tropsch
produced a real
industrial synthesis of hydrocarbons and oils under normal pressure with a
cobalt catalyst
and thorine. These processes were improved in 1930 and during world war 2
using nickel and
nickel-cobalt catalyst. Many companies improved the F-T process since then,
using costly
alloy catalysts without succeeding to eliminate problems of instability,
effectiveness,
profitability and necessity of refining. Adding sait, NaCl, to an iron
catalyst or to a nickel
catalyst solves part of these problems. See C.I.P.O no. 2,459,847 and C.I.P.O
no. 2,410,760.
About ail F-T processes produce a large variety of hydrocarbons. This is why
the necessity of
refining stands. I discovered a process for producing specific synthetic
gasolines or specific
synthetic diesels eliminating the necessity of refining.

SUMMARY
We can divide hydrocarbons in 3 groups: 1) small numbers of carbons =
CH4 to C4H10 natural gales... 2) medium numbers of carbons = C5H12 to C10H22
gasoiines... 3) large numbers of carbons = C13H28 to C19H40 diesels. If we
compress or
Iiquefy natural gases, we keep the same numbers of carbons. To produce
gasolines or diesels
using oniy natural gas (CH4), we must convert hydrocarbons with small numbers
of carbons
into hydrocarbons with medium or large numbers of carbons. In order to convert
naturel gas
into specific synthetic gasolines or specific synthetic diesels, we must use
specific synthesis
gas containing specific proportion of CH4.
The Fischer-Tropsch process uses a synthesis gas (H2 + CO) to produce
hydrocarbons following these proportions:
15 H2 (14%) + 7 CO (86%) = C7H16 (44%) + 7 H2O (56%). With any temperature,
with
any pressure or with any catalyst, the same proportions of the synthesis gas
(14% H2 + 86% CO) produces all groups of hydrocarbons, not only C7H16, even if
we add
sait (NaCI) to cataiysts. I discovered that if we remove H2 and use CH4
instead, we get a
new synthesis gas with specific properties. The synthesis gas (H2 + CO) in the
F-T formula
becomes (CH4 + CO). With a new synthesis gas containing 59% CH4 + 41%CO, we
produce
only a "medium number" group of hydrocarbons (gasolines). With a new synthesis
gas
containing 56% CH4 + 44% CO, we produce only a "targe number" group of
hydrocarbons
(diesels). Adding sait (NaCl) to the iron catalyst, or to any other metai
catalyst we may use,
is stiii essentiel because chlorine opens chemical chains extracting H2 from
CH4 and sodium
prevents crystais of oxygen from covering the iron catalyst, aiming chemical
reactions
towards production of a specific group of hydrocarbons. Doing so, the chemisai
equation to
produce synthetic gasolines:
CH4 (59%) + 2 CO (41%) = C7H16 (73% synthetic gasolines) + 2 H2O (27%)
Doing so, the chemical equation to produce synthetic diesels:
11 CH4 (56%) + 5 CO (44%) = C16H34 (72% synthetic diesels) + 5 H2O (28%).
"How to produce gasolines or diesels using only natural gas" also means that
we
must find a synthesis gas to produce CO. I discovered that we can produce CO
through
partial combustion of a synthesis gas having the exact proportions of 50% CH4
+ 50% 02.
We bum this synthesis gas in vacuum to produce 87% CO and 13% H2. We separate
CO
from H2 and we combine this CO to CH4 in order to have synthesis gases
descrived above.
