Abstract

The authors are studying aboveground oil shale retorting and have developed the LLNL Hot-Recycled-Solid (HRS) process as a generic, second-generation, rapid pyrolysis retorting system in which recycled shale is the solid heat carrier. In 1984-87, they operated a 1 ton-per-day HRS pilot plant to study retorting chemistry in an actual recirculation loop, Cena (1986). In 1989 they upgraded their laboratory pilot plant to process 4 ton-per-day of commercially sized shale, which will allow them, for the first time, to study pyrolysis and combustion chemistry using the full particle size, to produce enough oil for detailed characterization studies, to study environmental consequences, and to begin answering the many bulk solid handling questions concerning scale-up of the HRS process. In this paper the authors report on the status of their pilot plant operations. They have operated the facility circulating raw shale at ambient temperature and dolomite at elevated temperature. They plan the first hot shale run in November 1990. 5 refs., 16 figs., 4 tabs.

Results and interpretation of rapid-pyrolysis experiments using the LLNL solid-recycle oil shale retort

Conference Cena, R; Mallon, R

Virtually all rapid pyrolysis oil shale retorting processes currently under study utilize some form of hot-solid as the heat carrying medium. The conditions under which rapid retorting is achieved call for rapid mixing of the solid heat carrier and raw shale followed by a 2 to 3 minute soak period during which pyrolysis occurs. Both chemically active and inactive solid heat carriers have been proposed along with a number of processing strategies. To assess the merits of the various processing alternatives, a thorough understanding of the chemistry and physics involved in solid-recycle retorting is required.

LLNL oil shale project review

Conference Cena, R.

Livermore's oil shale project is funded by two budget authorities, two thirds from base technology development and one third from environmental science. Our base technology development combines fundamental chemistry research with operation of pilot retorts and mathematical modeling. We've studied mechanisms for oil coking and cracking and have developed a detailed model of this chemistry. We combine the detailed chemistry and physics into oil shale process models (OSP) to study scale-up of generic second generation Hot-Recycled-Solid (HRS) retorting systems and compare with results from our 4 tonne-per-day continuous-loop HRS pilot retorting facility. Our environmental science program focuses on identification ofmore »« less

A hot-recycled solid oil shale retorting process for the production of shale oil and specialty chemicals

Conference Cena, R

At Lawrence Livermore National Laboratory, we are studying Hot-Recycled-Solid (HRS) oil shale retorting processes through a series of fundamental studies, operation of a 4 tonne-per-day HRS pilot plant and development of an Oil Shale Process (OSP) mathematical model. Over the last two years, under an industrial CRADA with four major oil companies, we have completed a series of runs (H10-H27) using the pilot plant to demonstrate the technical feasibility of the technology, maintain and enhance the knowledge base gained over the past two decades through research and development and determine the follow on steps needed to advance the technology towardsmore »« less
Lawrence Livermore National Laboratory oil shale project quarterly report, July-September 1984. [Moving-bed retort]

Technical Report Lewis, A

Highlights of progress achieved during the quarter ending September, 1984, are summarized. Additional parameter studies using our moving-bed retort model were completed for an external-combustion, hot gas retort. Previously reported studies focused on effects of variations in the temperature and flow rate of the recycle gas and the dimensions of the retort. More recently, we investigated the effects of variations in shale grade, water content, flow rate, particle size, and bed porosity. We also considered effects of permeability contrast within a retort. The LLNL one-dimensional model for simulating oil shale retorting in an aboveground, moving-bed retort was applied to themore »« less
