A process for detecting, and monitoring, changes in the properties of a fluidized bed of particulate solids, especially a fluidized bed of particulate catalytic solids at elevated temperature wherein a low molecular weight hydrocarbon is converted, in the presence of steam and oxygen, to synthesis gas. Measurement is made of the magnitude of differential pressure fluctuations taken at different levels of bed elevation and these are recorded as a standard deviation, or normalized standard deviation, and directly related to particle size changes caused by agglomeration (growth) and/or attrition (size reduction). Operation of the process requires the use of fast response pressure transducers that are located in the bed and connected to an A/D board of a PC which records and accumulates the data for processing, and analysis.
A process for detecting, and monitoring, changes in the size of the particulate solids and resulting bubble size of a bed fluidized by ascending gases as caused by particle agglomeration or attrition, or both particle agglomeration and attrition during interaction or chemical reaction between said gas and solids which comprises:
In the production of hydrogen and carbon monoxide in a reaction zone by contacting together and reacting a low molecular weight hydrocarbon feed, steam and oxygen fed into the reaction zone to produce, at elevated temperatures, partial oxidation and steam reforming reactions, wherein the improvement comprises:
