    摘要： A process for naphtha cracking employing new synthetic catalyst of ultra-large pore crystalline material. The new crystalline material exhibits unusually large sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams at 50 torr and 25.degree. C., a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 Angstrom Units and a hexagonal arrangement of uniformly sized pores with a maximum perpendicular cross section of at least about 13 Angstrom units.An improved cracking reaction is provided for catalytic conversion of hydrocarbon feedstock which comprises contacting the feedstock under catalytic conversion conditions with acid metallosilicate solid catalyst having the structure of MCM-41 with hexagonal honeycomb lattice structure consisting essentially of uniform pores in the range of about 20 to 100 Angstroms. The cracking reaction is very selective, especially when conducted at temperature of about 425.degree. to 650.degree. C.

    摘要： Granular molecular sieve may be obtained, without necessitating any activng treatment, by subjecting a vinylidene chloride copolymer to a thermal carbonization treatment for removal of hydrochloric acid, pulverizing the resultant product to a grain size smaller than 100 mesh size, adding 15 to 35 parts by weight of a carbonaceous sintering agent and 8 to 15 parts by weight of an organic pelletizer capable of gas generation by heating to 100 parts by weight of the pulverized product, pelletizing the resultant mixture and carbonizing the resultant pellets at a temperature of 400 to 900.degree. C for a period of 2 to 6 hours. The pore diameter of this molecular sieve can be suitably controlled within a range of from 5 to 10 A by appropriately selecting the sintering agent and pelletizer employed and the conditions of the thermal treatment.
