  • Patent number: 12264117
    Abstract: The present invention is related to a process for the conversion of used cooking oil into aromatics (BTEX) hydrocarbon as petrochemical building blocks. The process provides an aromatic rich hydrocarbon from used cooking oil in the presence and absence of steam/hydrogen over supported bimetallic alumina-silicates zeolites. The catalyst contains no precious metal entities and may contain one metal form zinc (Zn), a second metal (X), comprising at least one selected from cobalt (Co), gallium (Ga), chromium (Cr), Iron (Fe) and third elements from cerium (Ce), boron (B) supported on alumina-silicates zeolites. The present invention relates to a catalyst excluding novel metals to produce aromatics in a continuous fixed bed reactor system under atmospheric pressure. More particularly, the present invention relates to a low-temperature process to produce aromatic over alumina-silicates zeolites. The process provides used cooking oil conversion of 84-89% with aromatic selectivity of 87-91%.

  • Patent number: 11654420
    Abstract: A process and catalyst are provided for the non-oxidative dehydrogenation of propane for the production of propylene as petrochemical building blocks. The process provides a direct single-step gas-phase dehydration of propane mixed with nitrogen in the presence and absence of steam/hydrogen over supported bimetallic alumina-silicates zeolites. The catalyst contains no precious metal entities and may contain one metal from group VIB in combination with another metal from group IIIA or IVA supported on FAU, MFI, KFI, BEA type alumina-silicates zeolites. The process provides a propane conversion of 18% to 52% with a propylene yield of 10% to 25%.

  • Publication number: 20120029179
    Abstract: The present invention relates to a process for preparing compound of formula (I) that is Cleistanthin A. The process comprises the steps of reacting compound of formula (II) with compound of formula (III) in the presence of a first solvent, quarternary ammonium salt and first alkali to form compound of formula (IV). The compound of formula (IV) is further treated with a second solvent and a second alkali to form compound of formula (I). The present invention also relates to the preparation of salt of compound of formula (IV) that is Cleistanthin A acetate.
