Processes and apparatus for reforming hydrocarbons to reduce the impact of contaminants created by non-catalyst coking. The reaction zone receives sulfur to inhibit the impact, and a control index is used to control the determine conditions with generally lower pressures. Additionally, a compression zone, pressure control zone and combustion zone operation are provided for the operation of the reaction zone at the generally lower pressures.

This present disclosure relates to processes and apparatuses for toluene and benzene methylation in an aromatics complex for producing paraxylene. More specifically, the present disclosure relates to processes and apparatuses for toluene and benzene methylation within an aromatics complex for producing paraxylene wherein an embodiment uses a reactor having a refractory comprising a low iron content refractory.

Processes and apparatuses for toluene and benzene methylation in an aromatics complex

A process and apparatus are disclosed for treating a hydrocarbon stream, the process including flowing the hydrocarbon stream through a hydrocarbon treating vessel, heating a portion of the hydrocarbon treating vessel to a predetermined temperature and for a predetermined amount of time and controlling sensitization and chloride stress corrosion cracking of the portion of the interior surface of the hydrocarbon treating vessel.

One exemplary embodiment can be a process for removing one or more scale deposits formed on a surface. The process can include contacting the surface with a composition for a period of time sufficient to remove the scale deposits that comprise coke or metal sulfides or mixtures thereof. Generally, the composition includes an effective amount of an organic acid and/or a salt thereof, and an effective amount of an oxidizing agent.

Process and composition for removing a scale deposit

A coating applied to at least a portion of the surfaces of reactors, reactor internals, other reactor components, and/or heater tubes is provided in order to minimize the formation of metal catalyzed coke in hydrocarbon conversion processes operating at temperatures at about 350&#xb0; C. (662&#xb0; F.) or greater and in reducing environments. These coatings may comprise Nickel coatings or complexes thereof, such as Ni&#x2014;Al, Ni&#x2014;Cr/Cr carbide, as well as aluminum painted coatings that are applied in a reduction cure process (e.g., application temperatures of about 600&#xb0; C. (1112&#xb0; F.)). Additionally, where HS is necessary for the process, such as to minimize thermal cracking, the coatings also reduce corrosion of base metal due to sulfidation attack and eliminate the requirement of continuous replacement of reactor internals and other components.

A process for producing light olefins from oxygenates wherein internal reactor are protected from metal-catalyzed coking preferably by employing a protective layer.

Methanol-to-olefins process with reduced coking

A catalyst for opening naphthenic rings has been developed. The catalyst comprises ruthenium and platinum as the active catalytic metals and a modifier with cerium being a preferred modifier. At least 50% of the platinum and ruthenium components are present as particles wherein more ruthenium is present on the surface of the particles than in the center. All of these components are dispersed on a metal oxide support such as aluminas. A ring opening process using the catalyst is also described.

Modified PT/RU catalyst for ring opening and process using the catalyst

A catalyst and process is disclosed to selectively upgrade a paraffinic feedstock to obtain an isoparaffin-rich product for blending into gasoline. The catalyst comprises a support of a sulfated oxide or hydroxide of a Group IVB (IUPAC 4) metal, a first component of at least one lanthanide element or yttrium component, which is preferably ytterbium, and at least one platinum-group metal component which is preferably platinum and a refractory-oxide binder having at least one platinum-group metal component dispersed thereon.

This invention provides a compact heat exchanger that has an effective geometry for heat transfer operations regardless of the heat conductivity of the material chosen for the fin materials. It has further been found that the use of adsorbent coated anodized aluminum for fin materials provides for a very efficient heat exchanger.

Reforming selective for the dehydrocyclization of paraffins to aromatics, is effected using a catalyst containing a platinum-group metal, a nonacidic large-pore molecular sieve, and a metal modifier which is positioned on the catalyst to be extrinsic to the pores of the molecular sieve. The use of this catalyst results in greater selectivity converting paraffins to aromatics and improved catalyst stability particularly when processing feedstocks containing small amounts of sulfur compounds.

Conductive thick film pigment-coated surfaces which possess desirable conductivity and solderability characteristics are formed from an alloy comprising a mixture of a nonnoble conductive metal, a noble metal and at least one oxidizable material. The oxidizable material is present in the alloy in an amount in the range of from about 5% to about 25% by weight, the nonnoble metal in an amount in the range of from about 94% to about 60% by weight and the noble metal in an amount in the range of from about 1% to about 15% by weight of the alloy. The desired product is prepared by admixing a nonnoble metal, an oxidizable material and a noble metal, arc-melting the mixture to form an alloy, grinding the arc-melted alloy to a powdered form, admixing the powder with the carrier binder, depositing said admixture on an inert surface, firing the admixture and surface in an oxygen-containing atmosphere at a temperature in the range of from about 500.degree. to about 950.degree. C. and fluxing the resultant conductive thick film pigment-coated surface with a zinc-chloride based flux to provide the desired product.

Conductive pigment-coated surfaces

Conductive pigment-coated surfaces may be prepared by alloying a nonnoble conductive metal with an oxidizable material, admixing the alloy with an organic vehicle and a binder to form an ink followed by firing the ink in an oxidizing atmosphere containing about 20% by volume of oxygen at a temperature in excess of 1000.degree. F. If so desired, a vitreous frit may also be present in the mixture. The resulting ink will possess desirable characteristics such as increased resistivity to oxidation, and increased firing strength when the oxidizable material such as boron is present in the alloy in an amount in the range of from about 12% to about 25% by weight.
