Refining and Upgrading of Synfuels from Coal and Oil Shales by Advanced Catalytic Processes. Tenth Interim Report. Revised Stock Balances and Updated Cost Estimates

摘要

Design studies and cost estimates have been published under this contract from 1978 through 1984. While each estimate was based on the best available data and methods at its publication date, cost indices changed and methods were improved with the passage of time. This report revises all the previous results to a common, consistent basis. The overall product yields, overall investments, and per-barrel refining costs summarized in Table 31 are now suitable for use in internal comparisons and any future evaluations where stand-alone synfuel refineries are under consideration. Reforming yield predictions are now based on actual data with coal naphthas. Reforming hydrogen production is higher than had been originally estimated, allowing smaller hydrogen plants and, hence, lower costs especially in the all-gasoline cases. Because of the above change, making all-gasoline is no longer clearly more expensive on a volume basis than making kerojet and gasoline, as had been previously concluded. Costs for the two product slates are now closer together and the most economic product slate is feed-dependent. 8 refs., 31 tabs. (ERA citation 10:029735)
