    Abstract: A process for producing a high methane content, synthetic pipeline gas from oil shale. Oil shale is processed so as to provide a shale oil fraction, and solids including shale fines and spent shale. The shale oil and a hydrogen rich gas are introduced into a hydrogasifier chamber which is maintained at a temperature of about 1,100*-1,600* F., and at a pressure of about 500-2,000 psig, so as to convert the shale oil by hydrogasification into a high methane content, synthetic pipeline gas, normally liquid aromatic hydrocarbons, and a carbonaceous solid residue. Pulverized solids are passed through the hydrogasifier and into a gasifier chamber, maintained at a pressure of about 500-2,000 psig. and at a temperature of about 1,500*-2,100* F., to remove the carbonaceous residue or coke formed in the hydrogasifier. Shale fines and spent shale are also introduced into the gasifier wherein a gaseous mixture is formed by reaction with steam and oxygen or with steam and air. The gaseous mixture is then converted to a hydrogen rich gas either directly, by a carbon monoxide shift reaction (when steam and oxygen are used in the gasifier) or indirectly, by the steam-iron process (when steam and air are used in the gasifier). In the steam-iron process, the gaseous mixture is the reducing agent for iron oxides formed when added steam is converted to hydrogen over the reduced iron oxides. The hydrogen rich gas is purified and primarily includes hydrogen alone, in the case of the steam-iron process, or a combination of hydrogen and methane, in the case of the carbon monoxide shift process. This hydrogen rich gas is thereafter introduced to the hydrogasifier chamber to form the high methane content gas. All or a portion of the solids leaving the gasifier are recirculated back to the hydrogasifier.

    Abstract translation: 一种生产甲烷含量高的合成管道气从油页岩中提取的方法。 处理油页岩以提供页岩油馏分和固体，包括页岩细粉和废页岩。 将页岩油和富氢气体引入加压气化器室中，该气化器室保持在约1100°-1,600°F的温度和约500-2,000psig的压力下，以通过加氢气化来转化页岩油 甲烷含量高，合成管道气体，通常为液态芳烃，含碳固体残渣。 将粉碎的固体通过加氢气化器进入气化器室，保持在约500-2,000psig的压力。 并在约1500°-2100°F的温度下除去在加氢气化器中形成的碳质残渣或焦炭。 页岩粉和废页岩也被引入到气化器中，其中通过与蒸汽和氧气或蒸汽和空气反应形成气态混合物。 然后将气体混合物直接通过一氧化碳转化反应（当在气化器中使用蒸气和氧气时）或间接地通过蒸汽 - 铁工艺（当在气化器中使用蒸汽和空气时） ）。 在蒸汽过程中，气体混合物是当加入的蒸汽在还原的氧化铁上转化为氢气时形成的氧化铁还原剂。
