摘要:A catalyst and process for synthesis of dimethyl ether from synthesis gas are disclosed. The catalyst and process allow dimethyl ether synthesis at low pressures (below 20 bars) at a conversion rate close to the expected equilibrium rate. The catalyst is a combination of a methanol synthesis catalyst with metal components comprising Cu, Zn, Al, Mn and Cs and a methanol dehydration catalyst, wherein the dehydration catalyst is a dehydration agent which allows optimum production of dimethyl ether.

摘要:The present disclosure provides a method of synthesizing an aluminosilicate molecular sieve by a crystal seed-assisted method, a natural aluminosilicate clay mineral treated and activated by an alkali is used as a crystal seed for synthesis of the aluminosilicate molecular sieve, and the target molecular sieve product is synthesized by hydrothermal crystallization, wherein the synthesis process does not require addition of conventional crystal seeds of a molecular sieve or use of any organic template agent, thus the synthesized product does not require a calcination process to remove the template agent. The method of synthesizing an aluminosilicate molecular sieve by a crystal seed-assisted method can meet the requirements of both crystallinity and nucleation time, and greatly reduce costs of synthesizing the aluminosilicate molecular sieve, and reduce the environmental pollution caused by removal of the template agent by calcinating.

摘要:The present invention relates to the technology of material surface modification and the preparation adsorption new material, which involves the preparation of CQDs and the application of CQDs on modifying water purification function material. Firstly, the CQDs with rich functional groups and specific graphene structure has been prepared based on the low-cost biomass. Then, modified the traditional adsorbent by prepared CQDs under the in situ synthesis process. Secondly, synthesis the CQDs basic on the organic waste-water under low-temperature hydrothermal treatment process. Then, prepared the CQDs modified water purification material by collecting the CQDs under the flocculation process. This invention can be used in the widely used in the field of modification and preparation of functional materials, because of it not only gives a new method to synthesis low-cost and high performance water purification material, but also provide a new idea to treat high toxicity and refractory organic waste-water.
