CATALYTIC PROCESSES AND SYSTEMS FOR BASE OIL PRODUCTION FROM LIGHT FEEDSTOCK |
摘要 |
Processes and catalyst systems are provided for dewaxing a light hydrocarbon feedstock to form a lubricant base oil. A layered catalyst system of the present invention may comprise a first hydroisomerization dewaxing catalyst disposed upstream from a second hydroisomerization dewaxing catalyst. Each of the first and second hydroisomerization dewaxing catalysts may be selective for the isomerization of n-paraffins. The first hydroisomerization catalyst may have a higher level of selectivity for the isomerization of n-paraffins than the second hydroisomerization dewaxing catalyst. |
