A catalyst and an improved process for producing olefins by catalytic naphtha cracking are described. The process provides relatively higher yields over a commercially important range of naphtha conversion, while providing about the same or lower yields of aromatics and methane over the range. In the process, a hydrocarbon naphtha feedstock including a hydrocarbon having about three to about twenty carbon atoms per molecule is passed into a reactor containing a pentasil zeolite catalyst. The catalyst includes about 0.1 to about 10 weight percent phosphorus and about 0.1 to about 10 weight percent of a promoter metal selected from the group consisting of gallium, germanium, tin and mixtures thereof. The hydrocarbon may be passed into the reactor together with a diluent selected from the group consisting of steam, nitrogen, methane, and ethane and mixtures thereof. Alternatively, the hydrocarbon may be passed into the reactor together with additional propane.

Process for manufacturing olefins

A process and catalyst are provided for dehydrogenating a hydrocarbon feedstock and producing an olefinic product. The process comprises contacting the feedstock at dehydrogenation conditions with a dehydrogenation catalyst comprising from about 0.01 weight percent to about 5.0 weight percent of a platinum group metal, from about 0.02 weight percent to about 10.0 weight percent of zinc, and a support component comprising borosilicate and an alkali metal.

Dehydrogenation catalyst and process

Processes using heterogeneous adsorbents are disclosed for purification of relatively impure unsaturated hydrocarbons such as olefins, which are typically produced by thermal cracking of suitable hydrocarbon feedstocks, by passing a feed stream, containing acetylenic impurities, and, optionally, saturated hydrocarbon gases, through a particulate bed predominantly comprising a support material having high a surface area on which is dispersed at least one metallic element. Adsorption is carried out in an essentially dihydrogen-free atmosphere within the bed, effecting selective and reversible adsorption and/or complexing of the contained acetylenic contaminants with the adsorbent, thereby obtaining purified effluent which contains less than a predetermined level of the acetylenic impurities. Selective and reversible adsorption and/or complexing of the contained acetylenic impurities with the adsorbent is continued until levels of acetylenic impurities in the effluent stream increase to a predetermined level. Thereafter, the resulting bed of adsorbent is regenerated in the presence of a reducing gas containing dihydrogen to effect release of the contained acetylenic impurities from the adsorbent.

Processes using heterogeneous adsorbents are disclosed for purification of olefins such as are typically produced by thermal cracking of suitable hydrocarbon feedstocks, by passing a stream of olefin having from 2 to about 8 carbon atoms, containing acetylenic impurities having the same or similar carbon content, and optionally saturated hydrocarbon gases, through a particulate bed of predominantly a support material having high surface area on which is dispersed at least one metallic element. Adsorption is carried out in an essentially dihydrogen-free atmosphere within the bed, selective and reversible adsorption and/or complexing of the contained acetylenic contaminants with the adsorbent, and thereby obtain purified effluent which contains less than a predetermined level of the acetylenic impurities. Selective and reversible adsorption and/or complexing of the contained acetylenic impurities with the adsorbent is continued until levels of acetylenic impurities in the effluent stream increase to a predetermined level. Thereafter the resulting bed of adsorbent is regenerated in the presence of a reducing gas containing dihydrogen to effect release of the contained acetylenic impurities from the adsorbent.

A fishing lure and method for producing the lure having a body formed from a metal from the group of titanium, niobium, tantalum, vanadium, zirconium and hafnium. The metal is colored by thermal oxidation or anodizing and formed into a desired body shape, such as a blade, spoon, or spinner. The hook and filament for attaching the hook to the lure body are formed of the same metal which the body is formed from.
