Title: Pressurized carbonization of coal liquefaction by-product materials: Fluor Advanced Liquefaction and Parsons' POGO processes

Abstract

Experiments were performed to determine the results of carbonization under pressure of three coal liquefaction product (or by-product) materials and thus supply data needed as a design base for two concepts for advanced coal liquefaction plants. Solid-liquid separation underflow (SLSU) and solvent from a hydroextraction process were carbonized at 900/sup 0/F in an inert atmosphere at pressures up to 400 psig. Vacuum still bottoms from the H-Coal process were pyrolyzed at 1100/sup 0/F in a methane atmosphere at 400 psig. Results from carbonization of hydroextraction solvent and SLSU show that (1) only 1 to 7 percent of the solvent is degraded during carbonization at 900/sup 0/F and 400 psig, (2) the heavier fraction of the residue contributed the most toward coke formation, and (3) increased pressure increases the degree of coking of the heavier fractions. Results from pyrolysis of the vacuum still bottoms material at 1100/sup 0/F and 400 psig indicated that (1) small amounts of liquid are produced, (2) a significant quality of gas is produced, and (3) higher temperature will probably be required to produce free-flowing char.

    A Materials-Process-Product Model of coal-process technology has been developed for the US Department of Energy. This model is an application of a methodology, previously developed under a grant from the National Science Foundation, for systematically analyzing an array of competing manufacturing technologies from economic, environmental, and energy policy perspectives. This report includes material on expansion of the MPPM Data Base in the Area of Advanced Gasification Processes. Volume I summarizes the work done and presents results of some analyses that was accomplished using the new data base elements. Volume II contains detailed descriptions of the processes and process models addedmore » to the MPPM Data Base.« less

  • Syncrudes produced from Wyodak coal in the Catalytic Two-Stage Liquefaction (CTSL) process were upgraded in pilot plant tests by hydrotreating with Chevron's commercial ICR 106 catalyst. Two CTSL syncrudes were studied; the first had an end point (EP) of about 625/sup 0/F; the second, an EP of about 850/sup 0/F. In this report, results are compared to those obtained with syncrudes from single-stage liquefaction processes and another two-stage process (Integrated Two-Stage Liquefaction (ITSL)). In general, products from the two-stage liquefaction processes were easier to upgrade than those from single-stage processes. However, with all of the syncrudes, relatively small increases inmore » EP made the oils more difficult to hydrotreat. The 625/sup 0/F EP CTSL was the easier to upgrade than the other syncrudes because of its relatively low EP and low heteroatom and high hydrogen contents. Both of the CTSL syncrudes were upgraded in a single hydrotreating step to diesel fuel, jet fuel, and a naphtha suitable for catalytic reforming. However, for the higher EP syncrude, the preferred route also required either a hydrocracking step or a second hydrotreating step. Transportation fuels made from all the syncrudes were fairly similar. Mainly, they were composed of cyclic hydrocarbons. There were, however, differences in product distributions depending upon syncrude boiling ranges. The middle-distillate fuels (jet and diesel) had high densities and, therefore, high volumetric energy contents. 14 refs., 16 figs., 49 tabs.« less

  • A laboratory evaluation of a 20-pound sample of Vacuum Tower Bottoms from the H-Coal liquefaction pilot plant at Catlettsburg, Kentucky was completed at Texaco's Montebello Research Laboratory. The sample, which was obtained from the liquefaction of Illinois No. 6 coal, was judged to be a suitable feedstock for the Texaco Gasification Processes. It can be charged directly to the gasifier as a molten fluid at a temperature of about 450/sup 0/F or it may be charged at ambient temperature as a water slurry of ground residue. Based on these results, operating conditions and yields were estimated for gasifying 1000 poundsmore » per hour of molten undiluted residue and for gasifying 1600 pounds per hour of solid residue in a water slurry both at a pressure of 1200 psig.« less

  • A laboratory evaluation of a 20-pound sample of Atmospheric Tower Bottoms from the H-Coal liquefaction pilot plant at Catlettsburg, Kentucky was completed at Texaco's Montebello Research Laboratory. The sample, which was obtained from the liquefaction of Illinois No. 6 coal, was judged to be a suitable feedstock for the Texaco Synthesis Gas Generation Process. It can be charged directly to the gasifier at a temperature of about 350/sup 0/F. Based on these results, operating conditions and yields were estimated for gasifying 1000 pounds per hour of molten undiluted residue at 1200 psig.

  • The Materials-Process-Product Model (MPPM) for coal conversion technologies, developed under a previous contract for the Department of Energy, has been modified to improve its versatility and flexibility for use in systems and policy analysis and the data base has been expanded and updated. The model consists of: a data base for coal-related materials and coal conversion processes; and an algorithmic structure that facilitates systematic evaluation of coal conversion process systems in response to exogenously specified variables such as tax policy, environmental limitations, and changes in process technologies and costs. The model is implemented as an interactive program. The user canmore » easily include new process data, revise existing data, and introduce exogenous data related to policy options. Sensitivity analyses are readily performed on parameters such as coal sulfur content, effluent limitations, and process performance parameters. The model is currently installed and operational on the DOE, Energy Information Agency Computer in Rockville, Maryland, on IBM-370 series machine. It is also available on the CDC CYBERNET system. Volume I of this report contains a summary of work accomplished on the current contract. Volume II, the appendices, contains updated information on the model structure and algorithms. Volume III is an updated User's Manual.« less
