In late 1977, Kanegafuchi .Chemical Industry Co.., Ltd. fKanegafuchi) started development of its new catalysts for the Stauffer oxychlorination process R-301 ^ R-303. Applying the catalysts to one of Kanegafuchi's commercial plants began in mid 1979, followed by their application to another commercial plant in late 1980. The performance of the new catalysts are shown in the following sections of this report, and the main features of the catalyst performance are: (1) High selectivity, especially a low ethyl chloride formation and a low ethylene combustion. (2) A low pressure drop and a low pressure drop rise in the reactor. I (3) High activity, especially in the case of K0C-R3 for the R-303. (4) Low hot spot temperature. (5) Easy control of the hot spot temperature. CCR 000018011 (To be continued) 2. Catalysts and Corresponding Reactor . Catalysts . KOC-101 KOC-201 KOC-R2 KOC-R3 . . . ................. Reactors. .

Summary of Catalyst Renewal at Kanegafuchi's Plants No.l and No.2 Please see the Table 1 in the attachment. 4 Operating Conditions, Pressure Drops, Product Analysis Data, etc. of the Plants Please see the Tables 2 and 3 for the No.2 plant and the Table 4 for the No.l plant in the attachment. 5. Temperature Profiles Please see the Figures 1^3 for the No.2 plant in the attachment. 6. Selectivity Kanegafuchi's new catalysts have shown very good selectivity, especially ethyl chloride formation and ethylene combustion have been less than those by conventional catalysts. OCR 000018012 2 Sy-- producl~~ Ethyl--chloride contents in the Tables 2^4 are shown by the gas chromatogram,area % as combined EDC (S-3Q9, S-3Q6, and m, t MM* _ S-307). 0.5%fof the combined stream corresponds to about 0.31 u*'7o of S-309 EDC, for example. CO and CO2 contents of the vent gas in the Tables 2^4 are very low, especially ethylene combustion remarkably decreases by KOC-R2 and KOC-R3. 7. Activity The new catalysts have high activity even at low hot spot tem peratures. As KOC-R3 for R-303 has very high, activity, a sufficient HC1 conversion can be obtained even at a low C2H4 excess (5 % 9%) and a low air excess (3 ^ 8%). In case of KOC-R3 for R-303, the steam drum pressure is also low, especially at No.2 plant - the Table 3. 8. Life The new catalysts have low deactivation velocity and low pressure rises. The lives of KOC-R2 and KOC-R3 are especially long. The temperature profiles by the attached Figures 1 v 3 show the long lives of the catalysts. Note: In the Table 3, the pressure drop of R-301 of the No.2 plant started to make a sharp rise in February 1982. It was later found by Kanegafuchi's investigations in August 1982 that the said rise had been caused by a clogging of the upper portion (about 20 m.m. below the top) of reactor tubes with soot, iron rust, lubricant oil, etc., but not by the powdering of catalyst. CCR 000018013 3 Hot Spot Temperature The hot spot temperature in the reactors drops by Kanegafuchi's new catalyst system, mainly because the catalysts are used with the new diluent KOD-55. Furthermore, the hot spot temperatures are stable even at the beginning of operation. 00001801^ OCR Kanegafuchi's New Catalyst System for R-304 Kanegafuchi has recently developed new catalysts which improve the efficiency of a vapor-phase addition chlorination of unconverted ethylene after an ethylene-rich oxychlorination process. The following are special features of the new catalysts: (1) High selectivity of the main reaction. (2) High conversion of ethylene and eacy control of the catalyst temperatures. (3) Remarkable decreases of VCM and ethylene concentration in the exhaust gas and COD in the waste water of the oxychlo rination process. Further information is available from Kanegafuchi upon request. 00018015 CCR 0 Table 1.
