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.

The length of the loop reaction zone and the nominal outside diameter of the generally cylindrical wall define a length/diameter ratio greater than 250. The reactor can be charged with a fluid slurry including an olefin monomer reactant, solid olefin polymer particles, and a liquid diluent. The concentration of the solid olefin polymer particles in the slurry can be greater than 40 weight percent based on the weight of polymer particles and the weight of liquid diluent. Also disclosed is a polymerization process carried out by polymerizing, in the loop reaction zone of a reactor as defined above, at least one olefin monomer in a liquid diluent to produce a fluid slurry as defined above.

摘要： An olefin polymerization process wherein monomer, diluent and catalyst are circulated in a continuous loop reactor and product slurry is recovered by means of a continuous product take off. The continuous product allows operating the reaction at significantly higher solids content in the circulating slurry. In a preferred embodiment, the slurry is heated in a flash line heater and passed to a high pressure flash where a majority of the diluent is separated and thereafter condensed by simple heat exchange, without compression, and thereafter recycled. Also an olefin polymerization process operating at higher reactor solids by virtue of more aggressive circulation.
