USE OF CARBON DIOXIDE AND OXYGEN IN THE REGENERATION OF THE ACID CONDENSATION CATALYST
The present disclosure provides a method for regenerating an acid condensation catalyst including reacting a fouled acid condensation catalyst in an acid condensation (AC) reactor with a regeneration feed gas comprising oxygen (O.sub.2) at a regeneration temperature to produce a regenerated acid condensation catalyst and an effluent gas comprising carbon dioxide (CO.sub.2). The method further includes fractionating the effluent gas into a liquid phase containing water and a vapor phase, (iii) mixing at least a portion of the vapor phase with O.sub.2, CO.sub.2, air, or a combination thereof to form the regeneration feed gas; and (iv) introducing the regeneration feed gas to the AC reactor to continue the reaction of step (i).
METHOD FOR REGENERATING A ZEOLITE-BASED HYDROCRACKING CATALYST, AND USE THEREOF IN A HYDROCRACKING PROCESS
The present invention relates to a process for the regeneration of an at least partially spent catalyst resulting from a hydrocracking process, said at least partially spent catalyst resulting from a fresh catalyst comprising at least one metal from group VIII, at least one metal from group VIb and a support comprising at least one zeolite, said process comprising at least one regeneration stage in which the at least partially spent catalyst is subjected to a heat and/or hydrothermal treatment in the presence of an oxygen-containing gas at a temperature of between 350 C. and 460 C. so as to obtain a regenerated catalyst, said process not comprising a subsequent rejuvenation stage of bringing said regenerated catalyst into contact with at least one organic or inorganic and acidic or basic compound.
Catalyst for residue suspended bed hydrocracking and preparation method and application thereof
A catalyst for residue suspended bed hydrocracking and a preparation method and application thereof are disclosed. The catalyst is obtained by mixing a VIIB or VIIIB group transition metal salt solution with a ferric salt solution, conducting parallel-flow precipitation with an alkaline solution, adding a silicon source, and then conducting aging, washing, drying, and calcination. The catalyst has a stable structure and excellent hydrogenation activity. When used in a residue suspended bed hydrocracking reaction, the yield of liquid is up to 91 wt %, the yield of gasoline and diesel oil is up to 60 wt %, and both the yield of gas and the yield of coke are low. The catalyst has a good application prospect in residue suspended bed hydroconversion process.
FISCHER-TROPSCH PRODUCTION OF HYDROCARBONS FROM METHANOL
The present disclosure relates generally to processes for performing an integrated Fischer-Tropsch synthesis of hydrocarbons using methanol. In particular, the disclosure relates to a process comprising: providing a first feed stream comprising methanol; contacting the first feed stream with a methanol decomposition catalyst to form a first product stream comprising CO and H.sub.2; providing a second feed stream comprising H.sub.2 and at least a portion of the CO of the first product stream; contacting the second feed stream with a Fischer-Tropsch catalyst to provide a second product stream comprising C.sub.5+ hydrocarbons.
Method for preparing a steam reforming catalyst, catalyst and related use
The present invention addresses to a method of preparing steam reforming catalysts, of the eggshell type, using a solution of glycerin, in polar solvent, preferably water, to occupy the pores of a support. Next, the solvent is removed and the support is impregnated with a nickel salt solution, which may contain promoters such as rare earths. The steps can be repeated until the desired content of the active phase and promoters is reached.
RED MUD AND MORDENITE ZEOLITE CATALYST FOR SIMULTANEOUS DEHALOGENATION AND CONVERSION OF PLASTIC DERIVED OIL TO FUELS AND CHEMICALS
Hybrid catalysts for simultaneous dehalogenation and cracking of plastic derived oil include composite particles, where each of the composite particles includes red mud particles and Mordenite zeolite particles. A process includes contacting a plastic derived oil stream with the hybrid catalyst in an FCC reactor to produce an FCC effluent and a used hybrid catalyst. The plastic derived oil stream comprises halogen-containing compounds, and contacting the plastic derived oil stream with the hybrid catalyst causes halogen-containing compounds to react to form hydrocarbons and hydrogen halides, where the hydrogen halides are adsorbed onto surfaces of the red mud particles. The FCC effluent has a concentration of the halogen-containing compounds less than the plastic derived oil stream. Contacting the plastic derived oil stream with the hybrid catalyst causes hydrocarbons in the plastic derived oil stream to undergo cracking reactions over the Mordenite zeolite particles to produce the FCC effluent.
RED MUD CATALYST FOR DEEP DEHALOGENATION OF PLASTIC DERIVED OIL AND PROCESSES USING THE SAME
Processes for decontaminating a plastic derived oil include contacting a plastic derived oil stream containing halogen-containing compounds with a decontamination catalyst at a reaction temperature of 350-450 C. to produce a decontaminated plastic derived oil and a used decontamination catalyst. The decontamination catalyst includes from 5-40 wt. % red mud particles, from 20-60 wt. % matrix material, and from 10-30 wt. % binder, per unit weight of the decontamination catalyst. Contacting the plastic derived oil stream with the decontamination catalyst at the reaction conditions causes halogen-containing compounds to react to form hydrocarbons and hydrogen halides, which further react with the red mud particles to produce metal halides on surfaces of the red mud particles. The decontaminated plastic derived oil has a concentration of the halogen-containing compounds less than a concentration of the halogen-containing compounds in the plastic derived oil stream.
