Testing items for catalytic slurry
Thread Content
The oil slurry testing laboratory of the facility reports a high solid content, but upon visual inspection we see that there is no catalyst present – it’s just ash. Our laboratory can only use a centrifuge to determine the solid content; it cannot be used to measure the ash content. I wonder if companies like yours carry out tests for this parameter as well
For oil slurry, we usually measure density and solid content. Ash analysis is also not done; we don’t have the equipment for it. But doing the first two things can also illustrate the point. :lol
We also determine the solid content; the ash content is sent to an external lab for testing.
In this case: 1. Usually, only the density and solid content of the slurry are measured; parameters such as ash content, boiling range, and composition groups are generally not analyzed and require external testing. 2. Apparently, it is recommended that the original poster take a sample of the slurry, place it on white paper, and spread it out to check whether there is a catalyst present or if it’s ash ； 3. Outsource the analysis of the solid content in the slurry or try another method for analyzing solid content, such as the combustion method
We generally do not perform ash analysis; it is only carried out upon request from the workshop. Our slurry is generally tested for density, solid content, and boiling range.
Generally, only the solid content and density are analyzed!
How can one see ash with the eyes? It’s possible to measure machine impurities by using filter paper for filtration, rinsing, and then weighing. Ash is what remains after burning directly; that’s the ash. The ash content of the mixed material can be higher.
Ash is what remains after direct burning; that’s what it means. Here, we dilute it with gasoline
The solid matter filtered through ashless filter paper was ignited in a weighed combustion vessel, and then the weight was measured. It’s about burning off the carbon and oil on the catalyst.
This should also be related to whether the slurry is ultimately sent for external use, reused, or sent to subsequent units
