TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The process further includes: determining whether carbon monoxide to hydrogen in the secondary gas stream meets the additional requirements of carbon monoxide and hydrogen for the predetermined (I), and where additional hydrogen is desired prior to the combining step, passing carbon monoxide through a water/gas shift where the carbon monoxide is mixed with water to produce hydrogen and carbon dioxide and then passing the remaining carbon monoxide and hydrogen to the combining step; cleaning the secondary gas stream and removing carbon dioxide and solids to produce a cleaned gas stream; adding a second catalyst to the methanol gas to form a second predetermined (I) and distilling the second predetermined (I) to produce the predetermined (I). The process of designing a plant for producing (I) further includes: determining whether carbon monoxide to hydrogen in a secondary gas stream from partial oxidation of the secondary feedstock meets the additional requirements of carbon monoxide and hydrogen for the predetermined (I) and determining whether a water/gas shift is required. In the process, the steam is used for the indirect heating step, where a raw primary Arundo donax feedstock has a water content of higher than 25%, and the process further includes drying the raw primary Arundo donax feedstock to produce the primary feed stock. The carbon dioxide is removed using an amine separator. The catalyst is a nickel and copper catalyst. The predetermined (I) gas is methanol gas. The primary Arundo donax feedstock consists essentially of Arundo donax and the secondary feedstock comprises substantially Arundo donax. EXAMPLE - The primary Arundo donax feedstock was fed into the indirectly-heated gasifier in the absence of air or oxygen, and gasified using steam or other heat source as a fluidizing medium. The gas stream evolved was cleaned and solids and carbon dioxide were removed. If only Arundo donax was used as the feedstock, the solids may consist only of ash or minerals such as sodium, nitrogen compounds, potassium, copper, silica or phosphorus. The exact mixture was determined by the composition of the primary Arundo donax feedstock. The carbon dioxide was typically scrubbed out of the gas stream using an amine separator. A secondary, Arundo donax feedstock was then partially oxidized in a gasifier using oxygen, where the secondary feedstock was a liquid or a gas, the feedstock was fed into a burner and partially oxidized. The heat produced from this step was used to heat the gasifier to gasify the primary Arundo donax feedstock. The gases produced from the partial oxidation process are either cleaned or sent to the water/gas shift reactor. Gases emerging from reactor were cleaned and solids and carbon dioxide were removed. Gases from the cleaning process were merged with primary gases. The merged gas stream was sent to the methanol reactor, which was supplied with catalyst (e.g. nickel and copper), and distilled to form methanol. The methanol was converted to methyl acetate, then split into ethanol and methanol.
