    摘要: Moving bed hydrocarbon conversion processes are disclosed wherein a carbonaceous material is deposited on a solid catalyst used in the conversion process to form a coked catalyst which is regenerated in a regeneration zone in order to remove the carbonaceous deposit material from the catalyst and provide a regenerated catalyst having an increased number of active catalyst sites relative to the coked catalyst. The regenerated catalyst is then added to the reaction zone at a rate effective to enhance the conversion to desired products without enhancing the conversion to undesired by-products. When a radial flow reaction zone is employed a relatively constant amount of active catalyst sites can be maintained through the reaction zone by increasing the thickness of annulus through which the catalyst flows in the lower section of the reaction zone wherein the catalyst is more severely coked and has fewer active catalyst sites. The conversion of aliphatic hetero compounds, such as methanol to produce olefins in the C.sub.2 -C.sub.4 carbon range is specifically exemplified.

    摘要: Hydrothermal treatment of silicoaluminophosphate molecular sieves at temperatures in excess of about 700.degree. C. for periods sufficient to destroy a large proportion of their acid sites while retaining at least 80 percent of their crystallinity is found to result in a catalyst for converting methanol to lower olefins having increased catalyst life, increased selectivity for C.sub.2 -C.sub.3 olefins and decreased selectivity for paraffin production than the untreated SAPO-n starting composition.

    摘要: This invention relates to an improved process for converting methanol to light olefins using an ELAPO catalyst. The catalyst comprises a metal aluminophosphate molecular sieve having the empirical formula (EL.sub.x Al.sub.y P.sub.z)O.sub.2 where EL is a metal and x,y and z are mole fractions of EL, Al and P respectively. Preferred metals are silicon, magnesium and cobalt, with silicon especially preferred. The molecular sieve catalyst is composed of particles at least 50% of which have a particle size less than 1.0 .mu.m and no more than 10% of the particles have a particle size greater than 2.0 .mu.m. It is also preferred that the metal content (x) be from about 0.005 and 0.05 mole fraction.

    摘要: Superior isomerization performance is obtained in an isomerization process employing a catalytic composition comprising a Group VIII noble metal and a hydrogen form mordenite incorporated with alumina. The superior isomerization performance is achieved using a catalyst composition having a surface area of at least 580 m.sup.2 /g. A novel method of preparing an isomerization catalyst having a surface area of at least 580 m.sup.2 /g is characterized by contacting a formed catalytic composite with an acidic aqueous solution prior to addition of the Group VIII noble metal. The isomerization process is particularly useful in the isomerization of a dimethylnaphthalene containing feedstock into a product that contains a higher concentration of the 2,6-dimethylnaphthalene isomer than did the feedstock.
