ABSTRACT:
This invention covers a process for making Octene from nix C4Feed by a low cost highly selective multistage process. The multi staging of reactors essentially provides lower cost than conventional processes. Two options are provided in FIGS.1and2as regards to configuration based on the same catalyst but as can be seen that FIG.1configuration is low cost option with very high selectivity. The process provides conversion of butene to Octene >95% and product purity >96%. Product can be fractionated and can have a high purity Octene product by removing the trimers/polymers from the octene product. As mentioned due to the nature of the process configuration, one achieves high yield and selectivity with low cost.
