1. Förfarande för rengöring av en sinter använd för filt-rering av en metallkatalytsuspension, kännetecknat av att sintern behandlas med en vattenlösning av väteperoxid för 5 att förtränga metallkatalyten ur porerna med hjälp av en gas utvecklad av den av metallkatalyten förorsakade nedbryt-ningen av väteperoxid, tills gasutvecklingen upphör som ett tecken pä att det inte längre finns betydande mängder metallkatalyt i sintern. 10
2. Förfarande enligt patentkravet 1 för rengöring av en filterenhet bestäende av sintrar som härstammar frän kata-lytisk hydrering av antrakinon eller dess derivat, genom att skölja filterenheten med lösningsmedel som använts tili 15 lösning av antrakinon eller dess derivat och genom att av-dunsta filterenheten för avlägsning av lösningsmedlet, kännetecknat av att den sköljda och avdunstade filterenheten behandlas med 5-50 % vattenlösning av väteperoxid sä länge eller sä mänga gänger att gas inte längre väsentligt utveck-20 las, varefter filterenheten tvättas med vatten och till slut torkas.
3. Förfarande enligt patentkravet 2, kännetecknat av att filterenheten behandlas med en 5-15 %, tili exempel 10 % 25 vattenlösning av väteperoxid.
4. Förfarande enligt patentkravet 2 eller 3, kännetecknat av att den med vatten tvättade filterenheten tvättas med en varm vattenlösning av syra som löser metallkatalyt, före 30 en ny väteperoxidbehandling, vattentvätt och slutlig tork-ning.
5. Förfarande enligt patentkravet 4, kännetecknat av att efter lösningsmedelssköljning och avdunstning tvättas fil- 35 terenheten med en varm basisk vattenlösning och sköljs med vatten före den egentliga väteperoxidbehandlingen. i3 86380
6. Förfarande enligt patentkravet 5, kännetecknat av att före tvätten med varm basisk vattenlösning utförs en behand-ling av filterenheten med en vattenlösning av väteperoxid och vattentvätt. 5
7. Förfarande enligt nägot av patentkraven 4-6, kännetecknat av att en 10-50 % vattenlösning av kvävesyra, vars temperatur är 20-80°C, används. 10
8. Förfarande enligt patentkravet 7, kännetecknat av att en 25-35 %, tili exempel 30 % vattenlösning av kvävesyra, vars temperatur är 60-70°C, tili exempel 65°C, används.
9. Förfarande enligt nägot av patentkraven 5-8, känneteck-15 nat av att en 1-20 %, företrädesvis ca. 5 % vattenlösning av NaOH används, vars temperatur är över 20°C, företrädesvis 70-90°C, tili exempel 80°C.
10. Förfarande enligt nägot av föregäende patentkraven, 20 kännetecknat av att en keramik- eller metallsinter tvättas, vilken använts för filtrering av en ädelmetallkatalyt, sär-skilt Pd-svärta.
