    摘要： The operating performance of a multi-stage fixed bed adiabatic reactor system with interstage cooling designed for the exothermic conversion of methanol to light olefins is improved by cofeeding small quantities of light olefins with the methanol feed whereby a more controllable operation is achieved. Catalyst activity and cycle length also improves significantly. The light olefins can be produced in situ during dehydration.

    摘要： A reformate richer in BTX content than the reformate obtained from the conventional catalytic reformation of a wide cut naphtha is obtained by splitting the naphtha into two fractions, catalytically reforming the heavy fraction sequentially through a series of at least three catalyst beds and introducing the light fraction into the feed to the last or the penultimate reactor.

    摘要： Process for the continuous catalytic dewaxing of lube containing feeds wherein the feed effectively moves countercurrently to the catalyst. The process is based on the discovery that in a two-stage catalytic dewaxing process the stage-two or back-end dewaxing catalyst shows a concave upward aging when it is used to produce a targeted pour point lube, but the back-end dewaxing catalyst can be used as a stage one or front-end dewaxing catalyst to produce an intermediate pour point product.

    摘要： A catalytic dewaxing process in which a hydrocarbon feed, usually a lubricant feed, is catalytically dewaxed in at least two catalytic dewaxing stages with an interstage separation of the light ends which are subjected to hydrogenation to saturate the olefins before the hydrotreated product is passed to the second dewaxing stage. The hydrotreated fraction may be the entire fraction below the lube boiling range with a lube feed or a lower boiling portion of it with separated higher boiling portions such as naphtha and distillate by-passing the second dewaxing step.

    摘要： An improved method and apparatus are disclosed for hydrodewaxing hydrocarbon feedstock, such as heavy distillate or residual feed. The feedstock is hydrodewaxed in a first step. The resulting first effluent is separated to form a first vapor stream containing olefinic products and a first liquid stream, with a pour point of about 30.degree. to about 100.degree. F. The first liquid stream is then introduced into a second catalytic reaction, where the first liquid stream is hydrodewaxed to a specification pour point less than about 30.degree. F. The method and apparatus may also comprise routing primary products of hydrodewaxing, which contain olefins, as they are removed from the dewaxed first effluent, through an MOGDL unit to convert the olefins to additional high quality lubes. Improvements are due to removal of primary by-products containing olefins which inhibit dewaxing and accelerate catalyst aging and may cause reactor upsets. The addition of the MOGDL unit increases lube yields.
