    摘要: 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.

    摘要: A process for removing sulfone from a liquid hydrocarbon containing a concentration of sulfone by mixing a liquid acid therewith and thereafter separating the resulting admixture into an acid phase and a hydrocarbon phase. The hydrocarbon phase has a concentration of sulfone less than such concentration in the liquid hydrocarbon.

    摘要: Disclosed is a process for separating sulfone from a hydrocarbon stream containing a small concentration sulfone by using water as an extraction solvent. The extraction solvent, laden with the removed sulfone, is further processed to separate the extraction solvent and water to thereby produce a sulfone product suitable for reused in an alkylation process or for sale as a dry sulfone end-product.

    摘要: A holding fixture for a wheel and tire assembly enabling a single person to perform an operation on the tire such as grooving or the like. The fixture comprises a first U-shaped bracket having a base for mounting on a wall or other vertical surface and legs extending perpendicularly from the vertical surface. A second similar U-shaped bracket has a vertical base and horizontal legs adjustably bolted to the legs of the first bracket. The vertical base of the second bracket supports a horizontally extending support tube. A rotatable tube segment has a wheel mounting plate for a wheel and tire assembly affixed to one of its ends and a slotted positioning ring affixed to its other end. The tube segment and its slotted ring and mounting plate are captively and rotatively mounted on the support tube so that a tire and wheel assembly affixed to the mounting plate is rotatable about the support tube. A lock assembly is affixed to the support tube and the base of the second bracket. The lock assembly is releasably engageable in any one of the slots of the slotted positioning ring to hold a tire and wheel assembly mounted on the mounting plate in any one of a number of predetermined rotative positions about the support tube.
