摘要： A method is disclosed for modifying a catalytic molecular sieve for shape-selective hydrocarbon conversions comprises: a) selectivating said catalytic molecular sieve by contacting with a silicon-containing selectivating agent; and b) calcining the selectivated catalytic molecular sieve at high temperature calcination conditions comprising temperatures greater than 700° C., which conditions are sufficient to reduce acid activity as measured by alpha value and increase diffusion barrier of said catalytic molecular sieve as measured by the rate of 2,3-dimethylbutane uptake, as compared to the selectivated catalyst. Catalytic molecular sieves thus prepared, such as silica-bound ZSM-5, and their use in hydrocarbon conversion processes such as aromatics isomerization, e.g., xylene isomerization, ethylbenzene conversion and aromatics disproportionation, e.g., toluene disproportionation are also disclosed.

摘要： A dry, regenerable solid oxide process directed to convert SO.sub.x from the flue gas stream from a power plant, a coal or oil-fired plant or process heat furnace, or an FCC regenerator to elemental sulfur without using a Claus unit, a hydrogen plant, a regeneration gas separation system, or a hydrogenation section. This dry, regenerable solid oxide process is also effective on Claus plant tail-gas. This process uses solid oxides, such as, for example, magnesium aluminates or spinels to remove sulfur oxides from flue gas streams. The solid oxide is then regenerated by a reducing gas to release the sulfur compounds contained on the solid oxide to produce a gas stream comprising hydrogen sulfide, sulfur oxides and elemental sulfur. The elemental sulfur is then condensed and recovered as a product and the resulting gas stream may be recycled to be reprocessed over the solid oxide.

摘要： There is provided a process directed to the use of gases containing or mixed with carbon monoxide, such as synthesis gas, to aid in the regeneration of sulfur oxide-sorbed solid oxides, such as magnesium aluminates or spinels. This process is especially useful in applications where the solid oxide is used to purify the flue gas stream from an FCC regenerator, coal or oil-fired plant, power plant or process heat furnace, or the tail gas from a Claus plant. The process is also useful to remove sulfur oxides from flue gases produced in solid fuel combusters. According to this invention, carbon monoxide may be used alone or in combination with other gases to make the regeneration of the solid oxide exothermic or less endothermic, thereby improving the effectiveness of the regeneration.
