红楼梦的作者简介摘要：Greater product yield and quality and continuous upgrading of shale oil with hydrogen-rich, purge mode off gas is attained by pulsing in situ retorts at different phas and intervals. In the process, flow of feed gas to the flame fronts of underground retorts are quentially stopped and purged while continuously retorting the oil shale to enhance transfer of nsible heat from the combustion zones to the retorting zones and enlarge the paration between the combustion zones and the advancing fronts of the retorting zones. The flame fronts can be purged with steam, water, carbon dioxide, nitrogen, hydrogen, combustion mode off gas, purge mode off gas, reactor off gas, or combinations thereof. The combustion mode off gas
and/or purge mode off gas can also be ud as part of the feed gas or fuel gas.
