Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
118 words
A METHOD FOR CONDUCTING CHEMICAL REACTIONS IN VAPOR PHASE WHICH COMPRISES FLOWING A SUSPENSION OF PARTICULATE SOLID MATERIAL IN A GASEOUS REACTION MIXTURE UPWARDLY THROUGH A REACTION ZONE AT A VELOCITY GREATER THAN THE TERMINAL SETTLING VELOCITY OF THE SOLID MATERIAL IN THE REACTION MIXTURE UNDER REACTION CONDITIONS OF TEMPERATURE AND PRESSURE, DIVIDING THE EFFLUENT FROM THE REACTION ZONE INTO A PLURALITY OF STREAMS, PASSING EACH OF SAID STREAMS TO A SEPARATE UNTROTTLED CYCLONE SEPARATOR OF SUBSTANTIALLY THE SAME THROUGHPUT CAPACITY AS THE OTHER CYCONES, THEREBY SEPARATING A MAJOR PORTION OF THE SOLID MATERIAL FROM THE REACTION PRODUCTS, PASSING THE SO-SEPARATED SOLID MATERIAL TO A TEMPERATURE ADJUSTMENT ZONE, ADJUSTING THE TEMPERATURE OF THE SOLID MATERIAL TO A VALUE
