A PROCESS FOR THE MANUFACTURE OF SYNTHESIS GAS BY PARTIAL OXIDATION OF A GASEOUS HYDROCARBON-CONTAINING FUEL USING A MULTI-ORIFICE (CO-ANNULAR) BURNER

摘要

A process for the manufacture of synthesis gas by reacting oxygen-containing gas, applied as oxidiser and gaseous hydrocarbon-containing fuel in a reaction zone of a non-catalytic gas generator comprising the steps of injecting the said fuel and the said oxidiser into the reaction zone through a multi-orifice (co-annular) burner comprising arrangement of n separate passages or channels coaxial with the longitudinal axis of said burner, wherein n is an integer >/= 2 (2, 3, 4, 5...) wherein the (n-1)<th> passage is the inner passage with respect to the n<th> passage, measured from the longitudinal axis of the said burner, and wherein geseous hydrocarbon-containing fuel and, optionally, a moderator is passed through one or more of the passages, but at least through the n<th> (outer) passage whereby at least one passage remains; oxidiser and, optionally, a moderator, is passed through one or more of the remaining passages, but at least through the (n-1)th passage. In any two adjacent passages in which oxidiser is passed through the one passage, and gaseous hydrocarbon-containing fuel is passed through the other passage, the said oxidiser has a higher velocity than said hydrocarbon-containing fuel.
