A process is proposed for producing synthesis gas with reduced steam export by catalytic steam reforming of a hydrocarbonaceous feed gas with steam in a multitude of reformer tubes in a burner-heated reformer furnace to form a steam reforming flue gas. This process includes a configuration of the reformer tubes as reformer tubes with internal heat exchange and the use of a structured catalyst. For amounts of export steam between 0 and 0.8 kg of export steam per m.sub.N.sup.3 of hydrogen produced, these features interact synergistically when particular steam reforming conditions are selected.

A device for processing waste is described herein that comprises an ion generator, a furnace chamber, a heat exchanger, a pollution control system, and a chimney. The ion generator converts atmospheric air into an ionized gas and the furnace chamber thermally decays the waste by combining the waste with a product of an interaction of the ionized gas and heat generated by the furnace chamber. The heat exchanger cools the excess gas. A wet scrubber system removes heavy metals and/or acid gases from the cooled excess gas to generate scrubbed excess gas, and a fixed bed coke system detoxifies the scrubbed excess gas by converting carbon monoxide, water, and steam in the scrubbed excess gas to carbon dioxide and hydrogen, and removing remaining acid gas, a remaining heavy metal, and/or a remaining dioxin from the scrubbed excess gas. The chimney transfers remaining scrubbed excess gas out of the device.
