Abstract: A SCM-34 molecular sieve, preparation method therefor and use thereof are provided. The SCM-34 molecular sieve contains aluminum, phosphorus, oxygen and optionally silicon. In the XRD diffraction data of the molecular sieve, a 2θ degree of the strongest peak within the range of 5-50° is 7.59±0.2. The SCM-34 molecular sieve has a new skeleton structure and can be used to prepare a metal-containing AFI type molecular sieve or an SAPO-17 molecular sieve.

Abstract: The application relates to processes and systems that use a furfural compound for producing five-membered carbocyclic rings that are unsaturated, such as cyclopentene and cyclopentadiene. Examples methods for conversion of furfural compounds may include converting a furfural compound to at least a five-membered, saturated carbocyclic ring, and converting the five-membered, saturated carbocyclic ring in a presence of a catalyst to at least a five-membered, unsaturated carbocyclic ring.

Abstract: Disclosed is a method of preparing a calcium phosphate catalyst, which comprises reacting a calcium salt with a phosphoric acid salt in aqueous ammonia, separating the precipitate resulting from the reaction mixture thus obtained, suitably shaping said precipitate, drying it, and subjecting it to heat treatment within a temperature range of 450.degree. to 600.degree. C. in the presence of steam mixed with at least one of the components selected from the group consisting of an inert gas, air, phosphoric an acid, aldehyde, an oxygen-containing heterocyclic compound, an alcohol, and a diene hydrocarbon.The reaction of calcium salts with phosphoric acid salts in aqueous ammonia is effected with the starting reactants taken in the molar ratio of 1.5:1 if no phosphoric acid treatment is used, or with the starting reactants in a molar ratio within the range of 1.5:1 to 5.0:1 if the reaction mixture is treated with a phosphoric acid solution to a pH of from 5.0 to 7.0.
