Abstract
A method for integrating several petroleum refining processes so as to efficiently produce tertiary alkyl ether compounds from a feed stream containing both saturated and unsaturated hydrocarbons is disclosed. An important step for forming isoolefins in the integrated process involves simultaneous catalytic conversion of an isoparaffin to an isoolefin and an n-olefin to an n-paraffin in a combination hydrogenation/dehydrogenation reactor. The thus produced isoolefin is reacted with a primary alcohol to form the desired tertiary alkyl ether compound in an ether forming process. Other conversion process included in the overall integration are an isomerization process to convert n-paraffins to isoparaffins and optionally an alkylation process to convert isoparaffins and olefins to an alkylate product.
