List refineries making methanol along with gasoline?

Question

reformer outlet gases are used for ammonia , methanol and hydrogen making for desulfurisation naptha/superior kerosine/atf/jetfuels/diesel/ and lube oil base stcoks in refineries.why not make methanol in refinries and blend in gasoline to reduce pollution/ oxygen demand to no of carbon atoms gasoline and its blends alone.

Answer 1

Methanol/gasoline blends are damaging to automobile fuel systems, thus there really no refineries making these blends.  There are actually two different types of reformers in refineries.  Steam reformers react hydrocarbons with water to produce synthesis gas.  This can be further processed to produce a number of materials including ammonia, methanol, or just plain hydrogen.  Within the context of petroleum refining, the most common product is hydrogen, which is then used for hydrotreating and hydrocracking to produce jet fuel, diesel or other low sulfur liquids.  Naphtha reforming, often just called reforming, converts low octane straight run naphtha to high octane reformate, which is then used as a gasoline blend stock.  A byproduct of this reaction is a hydrogen rich off gas.  This stream is also used for hydrotreating.  Off gas from naphtha reformers is not synthesis gas and cannot be used to produce methanol.
