Zeolite in the Hydrocarbon Industry

Abstract Warm asphalt mixtures have seen rapid development worldwide in recent years. Zeolite-based warm mix is one such type of warm mixture. In this paper, seven types of zeolites – comprising six natural zeolites and one synthetic zeolite – were selected. As additives for warm mix, their physical properties, such as density, water content and pore arrangements, were tested individually. To evaluate the compaction properties of zeolite-based warm asphalt mixtures, an AC-20 mixture was formulated and compaction tests were carried out. The results show that zeolites can reduce the compaction temperature for both Marshall and gyratory compaction. Temperature is the ... Read more

“Predicted” zeolites may fuel efficient processes | Zeolite.gr ​Scientists at Rice Univ. and the Univ. of Minnesota have identified synthetic materials that may purify ethanol more efficiently and greatly improve the separation of long-chain hydrocarbons in petroleum refining. The results show that predictive modeling of synthetic zeolites, a technique pioneered by Rice bioengineer Michael Deem, is highly effective and can help solve some of the most challenging problems facing industries that require efficient ways to separate or catalyze materials. Deem is co-author of a new study led by Univ. of Minnesota chemist Ilja Siepmann that appeared in Nature Communications. Zeolites ... Read more
