摘要:
The present disclosure is directed to novel crystalline germanosilicate compositions and methods of producing the same. In particular, the crystalline germanosilicate compositions are extra-large-pore compositions, designated CIT-13 possessing 10- and 14-membered rings. The disclosure describes methods of preparing these compositions using substituted benzyl-imidazolium organic structure-directing agents (OSDAs). Also disclosed are methods of using these crystalline compositions.

The present invention relates to an SCM-11 molecular sieve, a process for producing same and use thereof. The molecular sieve has an empirical chemical composition as illustrated by the formula " the first oxide the second oxide ", wherein the ratio by molar of the first oxide to the second oxide is more than 2, the first oxide is silica, the second oxide is at least one selected from the group consisting of germanium dioxide, alumina, boron oxide, iron oxide, gallium oxide, titanium oxide, rare earth oxides, indium oxide and vanadium oxide. The molecular sieve has specific XRD pattern, and can be used as an adsorbent or a catalyst for converting an organic compound.

摘要:
The present invention is related to a producing method of monocyclic aromatic hydrocarbons in which reaction products including monocyclic aromatic hydrocarbons are produced by bringing an oil feedstock and an aromatic production catalyst into contact with each other, the oil feedstock having a 10 volume % distillation temperature of more than or equal to 140°C and a 90 volume % distillation temperature of less than or equal to 380°C, the method including the steps of: introducing the oil feedstock into a cracking and reforming reaction apparatus (10) housing the aromatic production catalyst; bringing the oil feedstock and the aromatic production catalyst into contact with each other at the inside of the cracking and reforming reaction apparatus (10) housing the aromatic production catalyst; heating the oil feedstock in advance before introducing the oil feedstock into the cracking and reforming reaction apparatus (10) and forming a two-phase gas-liquid stream; separating the two-phase gas-liquid stream into a gas fraction and a liquid fraction; and introducing the gas fraction and the liquid fraction at different positions of the cracking and reforming reaction apparatus (10).

Methods for preparing bound non-acidic germanium zeolite catalysts that are ion-exchanged with cesium and impregnated with platinum are disclosed. The catalysts can be used in methods for aromatizing naphtha.
摘要:
This invention is for a catalyst for conversion of hydrocarbons. The catalyst is a medium pore germanium zeolite, a germanium aluminophosphate (AIPO) or a germanium silicoaluminophosphate (SAPO). At least one metal selected from Group 10 is deposited on the medium pore zeolite and, optionally on the germanium aluminophosphate (AIPO) or a germanium silicoaluminophosphate (SAPO). The catalyst is prepared by synthesizing a medium pore zeolite, an aluminophosphate (AIPO) or a silicoaluminophosphate (SAPO) with germanium incorporated into the framework and calcining medium pore germanium zeolite, germanium aluminophosphate (AIPO) or germanium silicoaluminophosphate (SAPO). At least one metal may be deposited on the germanium zeolite, germanium aluminophosphate (AIPO) or germanium silicoaluminophosphate (SAPO).
