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 …

Why it's free to use
- Filed January 14, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 14, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 14, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
