Abstract

A process for the production of a synthesis gas from a light hydrocarbon feed, steam and an oxygen-containing stream is provided in which the feed components are mixed to form a feed mixture. The process provides an inert disengaging zone separating the mixing zone from an active catalyst zone.

Claims (12)

1. A process for producing a synthesis gas from a light hydrocarbon stream comprising the steps of:

mixing a light hydrocarbon stream, steam, and an oxygen-containing gas to form a feed gas mixture in a mixing zone;

passing the feed gas mixture through an inert disengaging zone; and

passing the feed gas mixture to an active catalyst zone;

wherein the disengaging zone is at least partially filled with an inert mixing and shielding material, the inert mixing and shielding material is alumina, zirconium oxide, magnesium oxide, nickel or mixtures thereof; and

wherein the active catalyst zone is at least partially filled with a single partial oxidation catalyst.

2. A process for producing a synthesis gas from a light hydrocarbon stream comprising the steps of:

mixing a light hydrocarbon stream, steam, and an oxygen-containing gas to form a feed gas mixture in a mixing zone;

passing the feed gas mixture through an inert disengaging zone; and

passing the feed gas mixture to an active catalyst zone;

wherein the disengaging zone is at least partially filled with an inert mixing and shielding material, the inert mixing and shielding material has a particle size between about 25 mm and about 100 mm;

and wherein the active catalyst zone is at least partially filled with a single partial oxidation catalyst.
