Abstract:
The present invention relates to a method for at least partly uptaking a spilled liquid comprising at least one liquid hydrocarbon, the method comprising the step of contacting the at least one liquid hydrocarbon with a binder agent comprising at least one porous metal-organic framework material, wherein the at least one metal-organic framework material comprises at least one organic compound coordinated to at least one metal ion, wherein the at least one organic com- pound is based on imidazole, which is unsubstituted or substituted with one or more substituents independently selected from the group consisting of C 1-6 alkyl, phenyl and benzyl. The invention further relates to the use of such a binder agent for at least partly uptaking the liquid.
Abstract:
The invention relates to a process for the preparation of metal-organic frameworks (MOFs) in form of a homogenous powder, and a process wherein the metal-organic framework is molded into shaped bodies.
Abstract:
The present invention relates to a process for the production of a zeolitic material having a framework structure comprising YO2, wherein said process comprises: (1) preparing a mixture comprising one or more tetravalent elements Y in elemental form, one or more organic hydroxide salts, and one or more protic solvents; (2) reacting the mixture obtained in step (1) for converting at least part of the one or more tetravalent elements Y into an oxidic form thereof containing one or more Y-O single bonds and/or one or more Y=O double bonds; and (3) crystallizing a zeolitic material from the mixture obtained in step (2).
Abstract:
The present invention relates to a process for the production of a zeolitic material having a BEA-type framework structure comprising YO 2 and X 2 O 3 , wherein said process comprises the steps of (1) preparing a mixture comprising one or more sources for YO 2 , one or more sources for X 2 O 3 , and seed crystals comprising one or more zeolitic materials having a BEA-type framework structure; (2) crystallizing the mixture obtained in step (1); and (3) subjecting the zeolitic material having a BEA-type framework structure obtained in step (2) to an ion-exchange procedure with Cu and/or Fe; wherein Y is a tetravalent element, and X is a trivaient element, wherein the mixture provided in step (1) and crystallized in step (2) does not contain an organotemplate as structure-directing agent, and wherein the total amount of Cu and/or Fe in the ion-exchanged material obtained in step (3) ranges from 0.1 to 25 wt.-% calculated as Fe 2 O 3 and CuO, as well as to a zeolitic material having a BEA-type framework structure which may be obtained according to said process, and to a method for the treatment of NO x by selective catalytic reduction (SCR) using said zeolitic material.
