Title: Titania denitrification catalyst regeneration to remove arsenic - by contact with gas contg. hydrogen, then oxidising gas in simple, effective non-destructive process
Inventor: JUNG JUERGEN DR
IPC: B01J21/20
Filed: 1993-01-15
Granted: 1994-05-19
Abstract: Regeneration of catalysts (I) based on TiO2, which are poisoned with As and used for removing NOx from waste gases (II), comprises contacting (I) first with gas contg. H2 at 100-550 deg.C and then with an oxidising gas, pref. a gas contg. O2, at 20-550 deg.C.. USE/ADVANTAGE - The process is useful for regeneration (I) (e.g. plates and honeycombs) used for denitrification of (II) from thermal combustion processes, e.g. in power stations or refuse incinerators, and chemical processes, e.g. HNO3 or adipic acid mfr.. Almost complete regeneration is achieved in a simple, nondestructive process and it is not necessary to remove (I) from its steel mantle. The toxic H cpds. can be removed e.g. with an alkaline scrubbing liquor. In an example, a 124mm long honeycomb of catalyst (IA) contg. 70 (wt.)% TiO2, 8% WO3 and 0.5% V2O5 was charged with gas contg. As2O3 for 48 hours at 400 deg.C, giving a poisoned catalyst (IB) contg. 1% As. Regenerated catalyst (IC) was obtd. by heating at 2.5 K/min. to 450 deg.C in ca. 200 1/h N2 contg. 10 vol.% H2, giving 7.6 mmole water, then re-oxidn. in air at 450 deg.C.. The arsine and water formed during redn. were absorbed in 20% aq. NaOH soln.. The wash liquor contained 180mg As, i.e. As was removed quantitatively from (IB). These catalysts were used in denitrification of N2 contg. 2 vol.% O2, 10 vol.% H2O, 500 vol.ppm NOx with over 95% NO, 500 vol.ppm SO2 and 500 vol.ppm NH3. The denitrification activity of (IA)/(IB)/(IC) are various temps. was 50.5/30.6/35.8% at 300 deg.C; 55.4/32.8/41.4% at 320 deg.C; 61.3/36.0/50.4% at 350 deg.C; 65.5/37.6/56.4% at 380 deg.C; and 67.3/38.6/58.2% at 400 deg.C..

Compensation of the size, shape and position errors of the disc involves moving the cutter spindle stock (32) to any position causing contact of the sensing plates with the disc's upper surface, then moving it so that the clamped plates contact the probe head perpendicularly wrt. the direction of motion of the sensing plates. A reference surface is then detected using the probe head and correction values derived from the axle position for each measurement and added to corresp. values of the desired contour. USE/ADVANTAGE - For simple, automatic compensation of size, shape and position errors of cutting disc in machine coordinate system.
