Abstract: An improved method for the production of stoichiometric ratioed syngas comprises partially oxidizing a gaseous feedstock containing substantial amounts of methane in a gasifier to produce a hot synthesis gas stream that is passed in indirect heat exchange through a steam reforming catalytic reactor. A portion of the steam reforming reaction products are mixed with the cooled gasifier synthesis gas stream exiting the steam reforming catalytic reactor to form a combined synthesis gas stream, called a "stoichiometric ratioed synthesis gas." The stoichiometric ratioed synthesis gas stream can then be passed into a methanol synthesis unit at substantially the specifications for optimal methanol production with little or no external compression. In a second embodiment the gasifier unit is arranged and operated in parallel with a primary steam reformer unit.

Abstract: A selective deslagging operation is conducted in a partial oxidation reactor wherein a first predetermined portion of the reactor is selectively deslagged by derivatization while limiting derivatizing slag conditions in a second predetermined portion of the reactor. Selective deslagging can be accomplished by controlled oxidation conditions in the reactor that vary from one predetermined portion of the reactor to another. Thus, the slag present in one predetermined portion is derivatized and fluidized for removal from the reactor at a faster rate than the slag present in another portion of the reactor, which is not derivatized or is subjected to more limited derivatizing slag conditions. Derivatized slag can be differentiated from non-derivatized slag that does not flow or more limited derivatized slag that has a lower mass flow rate then the derivatized slag at conditions of controlled oxidation. The derivatized slag can then be selectively removed because it has attained a lower fluidizing temperature.
