A catalytic upgrading process includes introducing a feed comprising crude oil to a first catalytic deasphalting reactor to deasphalt the feed, thereby producing polymerized asphaltenes and deasphalted oil (DAO). The DAO is introduced to a steam cracking unit, thereby producing pyrolysis gas (PG), which is introduced into a selective hydrogenation unit, thereby producing an olefin-free product, which can then be introduced to a separation unit. The resulting benzene-toluene-xylenes (BTX)-containing stream and liquid petroleum gas (LPG) are separated, and the BTX-containing stream is introduced to a BTX complex to produce refined BTX. After deasphalting, a wash solvent may be introduced into the first catalytic deasphalting reactor to remove the polymerized asphaltenes, regenerate the catalyst, and produce a mixture comprising the wash solvent and the polymerized asphaltenes. The wash solvent is separated from the polymerized asphaltenes.

The present invention provides a long-lifetime SAPO-34 catalyst prepared from waste MTO catalyst as a raw material and a preparation method thereof. The method comprises the following steps: mixing the waste MTO catalyst fine powder with water; adding a phosphoric acid and an organic amine and stirring to obtain an initial gel mixture for SAPO-34 molecular sieve; crystallizing the initial gel mixture and then at least drying it to obtain a raw SAPO-34 molecular sieve powder; calcining the raw molecular sieve powder to obtain a SAPO-34 molecular sieve powder; then mixing it with a binder and a matrix carrier in water with stirring, and then aging it; and molding and then calcining it to obtain the long-lifetime SAPO-34 catalyst. The preparation method of the present invention uses MTO waste catalyst as a raw material to synthesize SAPO-34 molecular sieve in situ within a short time, and to prepare MTO catalysts having a long life and high selectivity for light olefins.

According to the invention a system and method for catalyst removal from MTO effluent is provided. The method includes removing catalyst from methanol to olefin effluent including contacting the methanol to olefin effluent with a wash oil separate the catalyst fines from the effluent into the wash oil and cool the effluent, separating the catalyst fines from the cooled effluent in a separator or a column to obtain an essentially catalyst free effluent, directing the catalyst free effluent out from the separator or the column, slurrying the separated catalyst fines to obtain a slurry and directing the slurry to one or more filters to filter out the catalyst.
