  • Publication number: 20240343982
    Abstract: The Invention discloses a method for improving the quality of oil products and increasing the yield of low-carbon olefins by catalytic cracking of bio-oil, which takes bio-oil or mixed oil of bio-oil and hydrocarbon oil as raw oil for catalytic cracking reaction. With this method, the octane number of the gasoline in product is obviously increased, simultaneously, the content of propylene and other low-carbon olefins in product is also improved.

  • Publication number: 20240342692
    Abstract: The invention discloses a bifunctional additive for increasing low-carbon olefins and reducing slurry in cracking product, wherein the dry-basis components of said additive is as follows: 40˜55 wt % of phosphorus-containing MFI zeolite, 0˜10 wt % of large pore type Y and Beta zeolites, 3˜20 wt % of inorganic binder, 8˜22 wt % of inorganic matrix composed of alumina and amorphous silica-alumina and 15˜40 wt % of clay. The bifunctional additive is mainly used to facilitate production rate of cracked LPG and increase concentration of propylene in LPG and octane number of produced the gasoline, and at the same time reduce the yield of slurry in the cracking products. The invention also discloses its preparation method and application of said additive.

  • Publication number: 20230096172
    Abstract: The invention discloses a catalyst for propane dehydrogenation to propylene and a preparation method and application thereof. The catalyst comprises a support, an active component and promoters supported on the carrier. Among them, the carrier is alumina ball, the active component is platinum group metal, the promoters include three kinds: rare earth elements (Y, La, Ce, Pr, Nd), tin, and alkali metal elements (Li, Na, K). When the catalyst is used for propane dehydrogenation to propylene, higher propane conversion and propylene selectivity are obtained.

  • Publication number: 20230101996
    Abstract: The invention relates to a process, unit and reaction system of low-carbon alkane dehydrogenation, which comprises the following steps: C3-C5 low-carbon alkane feed gas, together with CO and/or CO2 process gas, get into reactor after being preheated to 200-500° C., contact with a Cr—Ce—Cl/Al2O3 dehydrogenation catalyst, a Cu—Ce—Ca—Cl/Al2O3 thermal generating agent and thermal storage/support inert alumina balls, and convert to dehydrogenation products for 5-30 minutes under the conditions: temperature, 500-700° C., pressure, 10-100 kPa and weight hourly space velocity (WHSV), 0.1-5 hours?1. The products formed enter the downstream separation unit for separating out the low-carbon alkenes. The periodic regeneration process of the catalyst bed includes steam purging, hot air regenerating, bed heating, evacuating and reducing at 560 to 730° C. and 0.01 to 1 MPa. Each cycle needs about 10-70 minutes.
