Recent improvements in the Rheniforming process result in increased efficiency for production of gasoline blending stocks, aromatic chemicals, and hydrogen. These advances are based upon the development and commercial demonstration of an improved catalyst and new operating procedures. A new, less costly Rheniforming catalyst, Type E, is more active and even more stable and selective than previous Rheniforming catalysts. The new operating techniques involve control of on-stream catalyst chemistry to maximize selectivity and run length. The improvements permit lower pressure operation and thus increased yields of desired products, as well as decreased process energy consumption. Most of these advantages can be realized in existing plants. Still larger benefits can be obtained in new Rheniformers designed to take full advantage of the catalyst and process improvements. Experimental evidence indicates that long-cycle, semiregenerative Rheniforming can maintain higher average selectivity than cyclic or continuous reforming processes using platinum-rhenium catalysts. These catalysts show large, gradual increases in selectivity with time on-stream that continue through an appreciable portion of each cycle. The selectivity improvement decreases as the feed end point increases. As a consequence of this selectivity increase effect, platinum-rhenium catalysts can produce higher run-average liquid and hydrogen yields in long-cycle operation than in processes involving frequent regeneration.
