Abstract:

This disclosure relates to a novel method of making and recovering M41S family molecular sieve materials using synthesis mixtures having high solids-content and without a purification step. The solids-content, for example, is in a range from about 20 wt. % to 50 wt. %. The method also includes the step of mixing at least a portion of the M41S made with another material to form a composition, wherein the amount of said material to be mixed with said M41S product is such that said composition having less than 10 wt. % free fluid. The material mixed with the M41S made includes metal oxides, metal nitrides, metal carbides and mixtures thereof, as well as absorptive material capable of absorbing mother liquor and selected from the group consisting of carbon silica, alumina, titania, zirconia and mixtures thereof. The amount of the wastewater generated by this novel method is reduced by at least 50% to as much as 100% as comparing with conventional method of making M41S materials. By reducing and/or eliminating at least a portion of the wastewater generated in the synthesis product, the new method reduces cost of making of M41S materials and provides a more environmentally-friendly synthesis product.

US Classification:

585407, 585471, 585899, 423702, 423705, 423700

Abstract:

In a process for producing a phosphorus-modified zeolite catalyst, an aqueous reaction mixture comprising a source of silica and a source of an organic directing agent effective to direct the synthesis of a desired zeolite is heated at a temperature and for a time sufficient to produce crystals of the desired zeolite. Wet zeolite crystals can then be separated from the reaction mixture and, without removing all the water from the wet zeolite crystals, the zeolite can be converted into the ammonium form by ion exchange, and the crystals can be treated with a phosphorus compound. The phosphorus-treated, ammonium-exchanged zeolite can then be formed into a catalyst to be heated in one or more stages to remove the water and organic directing agent from the zeolite crystals and to convert the zeolite to the hydrogen form.

US Classification:

502 87, 423700

Abstract:

In a process for producing a molecular sieve material, water, at least one source of an oxide of a tetravalent and/or a trivalent element and at least one structure directing agent is mixed in a reactor equipped with a mixer having a Froude number of at least 1, to produce a molecular sieve synthesis mixture having a solids content of at least about 20 wt %. The molecular sieve synthesis mixture is heated in the reactor while agitating the mixture with said mixer to form crystals of said molecular sieve material and the molecular sieve crystals are subsequently recovered from the reactor.

US Classification:

585267, 423704, 502 60, 502 74

Abstract:

A process is described for producing an M41S family molecular sieve. The process comprises preparing a synthesis mixture capable of forming said molecular sieve in a reactor, which is equipped with a mixer having a Froude number of at least 1, said synthesis mixture having a solids content of at least 20 wt %. The synthesis mixture is heated in the reactor while agitating the mixture with said mixer to form a product mixture comprising water and crystals of said molecular sieve material. Thereafter at least part of the water is removed from the product mixture in the reactor so as to decrease the water content of the product mixture inside the reactor by at least 5 wt %.

Abstract:

Methods are provided for using a dewaxing catalyst formed using at least two structure directing agents for production of a lubricant base stock. For example, ZSM-48 crystals formed using multiple directing agents (and/or formulated catalysts made using such crystals) can have an increased activity and/or can provide an improved yield during catalytic production of lubricant base stocks. Additionally or alternately, ZSM-48 crystals formed using multiple directing agents (and/or formulated catalysts made using such crystals) can provide improved aromatic saturation during processing of a feed for lubricant base stock production.
