HCoal Syncrude product streams, prepared from Illinois No. 6, Wyodak, or West Kentucky No. 11 coal were obtained from the HCoal Process Development Unit (PDU) and analyzed for physical properties, elemental compositions, trace metal levels, and molecular composition. The trace metal levels are generally low in all except the heavy fuel oils.

The main gas components produced in the process of coal oxidation and spontaneous combustion include CO, CO 2, CH 4, C 2 H 4, C 2 H 6, and C 2 H 2. Among them, coal reacts with oxygen at ordinary temperatures to produce CO, CO 2, and CH 4 as well as including coal analysis. In the part of the index gas detection experiment, the aforementioned ...

the USA at the same time: the Exxon Donor Solvent (EDS) process and the HCoal process. The distinguishing feature of the EDS process was a separate solvent hydrogenation step to carefully control the hydrogen donor characteristics of the solvent, and the most important feature of the HCoal process was its use of an ebullated bed reactor.

The most important process of this group is the HCoal process, developed by Hydrocarbon Research, Inc. (HRI) as an outgrowth of previous work on the hydrogenation of petroleum fractions. The development of this process was sponsored by ERDA/US DOE and a large group of oil companies (DOE, 2015b; Xinjua News, 2014). Very few DCL programs were ...

The HCoal process, developed by Hydrocarbon Research, Inc., in 1963, mixes pulverized coal with recycled liquids, hydrogen and a catalyst in the ebullated bed reactor. The advantages of this process are that dissolution and oil upgrading take place in a single reactor, the products have a high H:C ratio and a fast reaction time, while the main ...

The objective of this work was to evaluate the applicability of commercial UOP hydrotreating and reforming processes to naphthas derived from the HCoal process. Three naphthas were studied. One was the primary naphtha generated from the HCoal syncrude operation. The other two products were from hydrocracking HCoal gas oil.

The rerun HCoal atmospheric still bottoms (Hcoal gas oil) were used to evaluate the relative hydrogenation activity of three UOP commercial catalysts. The UOPDCB catalyst, which was found to have the highest hydrogenation activity, was employed in the HCoal gas oil hydrotreating process more » variable studies.

After decades of research, the Bergius process, SRCI, SRCII, costeam process, and Hcoal process have proven to be efficient and costeffective to produce synfuel from direct liquefaction [16]. The main difference between SRCI, SRCII, and Hcoal is the addition of hydrogen and catalysts during the liquefaction phases.

Abstract. A large coalliquefaction pilot plant is in operation at Catlettsburg, Kentucky, expanding on the HCoal technology. The pilot plant operated very successfully during 1981, confirming research yield data on eastern bituminous coal, demonstrating operability of the process, and resulting in a significant accumulation of engineering data.
