Claims
- 1. A process for the production of synthesis gas which comprises contacting methanol in the vapor phase at a temperature in the range of from 200.degree. to 600.degree. C. and a pressure up to 100 atmospheres with a catalyst consisting essentially of an amorphous alumino-silicate prepared by mixing under reaction conditions which effect formation of said alumino-silicate, a source of silica, a source of alumina, a source of alkali metal, water, and one or more polyamines other than a diamine.
- 2. A process according to claim 1 wherein said polyamine is selected from polyethylene polyamines having the formula: ##STR4## wherein x is an integer greater than 1 and R.sup.1 is selected from hydrogen, alkyl groups containing from 1 to 6 carbon atoms, cycloaliphatic groups and aromatic groups.
- 3. A process according to claim 2 wherein R.sup.1 in said polyethylene polyamine having the formula (I) is hydrogen.
- 4. A process according to claim 1 wherein said polyamine is triethylene tetramine.
- 5. A process according to claim 1 wherein said polyamine has the formula: ##STR5## wherein x is an integer greater than 1 and R.sup.1 is selected from hydrogen, alkyl groups containing from 1 to 6 carbon atoms, cycloaliphatic groups and aromatic groups.
- 6. A process according to claim 1 wherein said polyamine has the formula: ##STR6## wherein y=a, b, c . . . z, in which a is an integer greater than 1 and b, c . . . z are either zero or integers, R.sup.3 is hydrogen or a monovalent organic radical and R.sup.4 is a divalent organic radical.
- 7. A process according to claim 1 wherein said polyamine has the formula:
- H.sub.2 N.(CH.sub.2).sub.2 [NH.CH.sub.2.CH(R.sup.5).CH.sub.2 ].sub.x NH.sub.2 (IV)
- wherein R.sup.5 is either a hydrogen atom or a methyl radical and x is an integer having a value in the range 1 to 10.
- 8. A process according to claim 1 wherein said polyamine has the formula:
- H.sub.2 N[CH.sub.2.CH.(R.sup.5).CH.sub.2 NH].sub.w (CH.sub.2).sub.2 [NH.CH.sub.2.CH(R.sup.5).CH.sub.2 ].sub.z NH.sub.2
- wherein R.sup.5 is either a hydrogen atom or a methyl radical and w and z are integers in the range 1 to 10.
- 9. A process according to claim 1 wherein said conditions which effect formation of said aluminosilicate are a temperature in the range 80.degree. to 210.degree. C., a pressure in the range 70 to 400 psig and a reaction time in the range 20 to 100 hours.
- 10. A process according to claim 1 wherein in said mixture the ratio of said silica source to said alumina source is in the range from 10:1 to 150:1 based on the equivalent moles of silica and alumina in the respective sources, said alkali metal source is present in an amount of from 50 to 0.02 moles of alkali metal per mole equivalent of total silica and alumina in the respective sources and said polyamine is present in an amount from 50 to 0.02 moles per mole equivalent of total silica and alumina in the respective sources.
