Method of extracting solids-free liquid reaction products from a reaction area containing therein dispersed solid catalytic material

Claim 1

IN A PROCESS WHEREIN REACTANT COMPOUNDS ARE DISSOLVED IN A LIQUID REACTION MEDIUM AND CATALYTICALLY REACTED IN A REACTION AREA CONTAINING FINELY DIVIDED CATALYTIC SOLIDS UNIFORMLY SUSPENDED IN SAID LIQUID MEDIUM, THE IMPROVEMENT WHICH COMPRISES EXTRACTING A PREDETERMINED QUANTITY OF SOLIDS-FREE LIQUID FROM SAID REACTION AREA THROUGH A FILTER LAYER WITH THE AID OF A PUMP WORKING AT FROM 1 TO 500 SUCTION AND PRESSURE STROKES PERMINUTE, ACCUMULATING FINELY DIVIDED CATALYTIC SOLIDS ON THE REACTION AREA SIDE OF THE FILTER LAYER, REMOVING A PORTION OF SAID EXTRACTED SOLIDS-FREE LIQUID, PERIODICALLY RETURNING THE REMAINING PORTION OF SAID SOLIDS-FREE LIQUID ON THE PUMP PRESSURE STROKE BACK FROM THE SUCTION SIDE THROUGH THE FILTER LAYER AND INTO THE REACTION AREA INTO DISLODGE SAID CATALYTIC SOLIDS FROM THE FILTER LAYER INTO THE REACTION AREA, AND THUS RETAINING SAID CATALYTIC SOLIDS WITHIN SAID REACTION AREA IN A CONSTANTLY SUSPENDED AND DISPERSED CONDITION.
