    摘要: The present invention relates to a polypeptide tag and a method using said polypeptide tag sequence for immobilizing a protein on a microporous material, said microporous material is selected from the group consisting of zeolite or similar solid surfaces whereby loss of activity of said protein is less than 10% of the initial activity prior to immobilization, the method comprising the steps of: 1. Selecting a polypeptide tag capable of binding to the surface, 2. Immobilizing said protein by the steps of: attaching said polypeptide tag to the protein, and binding said polypeptide tag to the solid surface where step (a) and (b) is performed simultaneously or sequentially and when performed sequentially, the order of step (a) and (b) is random, subject to the limitation that the polypeptide tag does not consist only of histidine residues.

    摘要: A process for producing crystalline microporous silico-alumino-phosphates with controlled Si content from a mixture of reactive sources of SiO.sub.2, Al.sub.2 O.sub.3 and P.sub.2 O.sub.5 and an organic template material, by combining at least a portion of the Al source and the P source in the absence of the Si source, mixing the resulting mixture with any remaining Al source, the Si source and the organic template material to obtain a gel, and heating the gel to obtain crystallization, wherein the Al and Si sources in the reaction mixture are mixed in the same mole ratios as in the crystalline microporous silica-alumino-phosphate to be produced, the P source is added in stoichiometric excess and hydrochloric acid is added at the same time as the P source, in a quantity such that the ratio of silica to hydrochloric acid in the gel is kept between 0.3 and 3. The invention also provides a crystalline microporous silico-alumino-phosphate produced by the process, and the use of such silico-alumino-phosphate as a catalyst for producing olefins from methanol.
