    • A process for the production of oxygenated C2 hydrocarbons from cellulose is disclosed. The input cellulose waste is gasified using steam in the absence of air and the primary gaseous products of carbon monoxide and hydrogen are subjected to heat, pressure, and catalysts to form methyl alcohol. Carbon monoxide is added to the methyl alcohol and further subjected to heat, pressure and catalysts to form acetic acid. The acetic acid is purified using a distillation tower, and removed for sale. Output production is increased by adding further carbon monoxide and hydrogen from burners used to heat the gasifiers. Further carbon monoxide and hydrogen are also produced by steam gasification of the carbon residue to promote a water/gas shift. These gases are fed into the gas stream produced by the gasification of cellulose, and provide more feedstock for the reactions. The three input gas streams arising from: 1) the steam gasification of cellulose; 2) the water/gas shift in the carbon reactor; and 3) the sub-stoichiometic oxygen burning of input burner gas to heat both retorts, maximize the output chemical production while reducing the consumption of energy needed for processing the cellulose and the carbon.
    • 公开了一种从纤维素生产含氧C2烃的方法。 输入的纤维素废物在没有空气的情况下使用蒸汽气化,并且一氧化碳和氢气的主要气态产物经受热,压力和催化剂以形成甲醇。 将一氧化碳加入到甲醇中,并进一步进行加热,加压和催化剂以形成乙酸。 使用蒸馏塔纯化乙酸,并将其除去。 通过从用于加热气化器的燃烧器中进一步加入一氧化碳和氢气来增加输出产量。 通过碳残余物的蒸汽气化也产生进一步的一氧化碳和氢气,以促进水/气转移。 将这些气体进料到由纤维素气化产生的气流中,为反应提供更多的原料。 三种输入气流产生于:1)纤维素的蒸汽气化; 2)碳反应堆中的水/气转移; 和3)输入燃烧器气体的亚化学计量氧气燃烧以加热两个蒸馏器,最大化输出化学生产,同时减少加工纤维素和碳所需的能量消耗。
