Double Down: Use PTQ in Tandem with USPTO

“There was this huge world out there, independent of us human beings and standing before us like a great, eternal riddle, at least partly accessible to our inspection and thought. The contemplation of that world beckoned like a liberation.” -- Albert Einstein (German born American Physicist who developed the special and general theories of relativity. 1879-1955)

Sometimes a really useful tool can be made even more useful by combining it with another really useful tool.

The advantages of catalyst accessibility
Fluid catalytic cracking is a diffusion limited process; nevertheless, the industry has evolved towards short contact time to minimise thermal cracking while simultaneously using a high catalyst to oil ratio (CTO) to maximise influence of the catalyst’s cracking and selectivity characteristics. With this elevated impact of catalyst architecture on yields, the opportunity cost of poor catalyst design is significant for the modern refiner. A key factor in catalyst architecture is accessibility. Accessibility is conceptually defined as the ability of large molecular structures to interact with the active cracking sites present on catalyst within a given time frame. While active sites do exist on the catalyst surface, the bulk remain buried inside a tortuous pore system with often limited accessibility. These sites go unused in poor catalyst designs. Albemarle offers refiners an efficient and unique test to quantify catalyst accessibility. [Excerpt]

United States Patent  6,828,153
Jonker ,   et al.   December 7, 2004
Method and apparatus for measuring the accessibility of porous materials with regard to large compounds
Abstract
The present invention provides a method for testing the accessibility of porous materials with regard to large, often high-molecular weight compounds and correlating said accessibility to the porous material's accessibility under conditions of use, i.e. the application conditions.
