    摘要： An integrated process for conversion of a hydrocarbon stream comprising light naphtha to enhanced value products. The process includes passing the hydrocarbon stream through a first reactor, the first reactor being a catalytic bed reactor with a dual-function catalyst to simultaneously reform light naphtha to BTEX and crack light naphtha to ethane, propane, and butanes. Further, the process includes passing an effluent of the first reactor to a gas-liquid separating unit to generate a liquid stream and a gas stream, and passing the gas stream to a gas separator unit to remove hydrogen gas and methane and generate an enhanced gas stream. The process further includes passing the enhanced gas stream through a second reactor, the second reactor being a pyrolysis unit operated at steam cracking conditions to convert ethane, propane, and butanes in the enhanced gas stream to light. An associated system for performing the process is also provided wherein the integrated process does not include passage of a process stream to a separate and independent hydrocracking unit to crack light alkanes in the hydrocarbon stream to smaller alkanes.

    摘要： Examples described herein provide a method for characterizing a catalyst in a chemisorption unit. The method includes treating a catalyst sample with gas blend comprising ammonia in an inert gas and performing a first temperature programmed desorption (TPD) to desorb the ammonia from the catalyst sample. A temperature programmed reduction (TPR) of the catalyst sample is performed with hydrogen. The catalyst sample is treated after the TPR with a gas blend comprising ammonia in an inert gas. A second temperature programmed desorption is performed to desorb the ammonia from the catalyst sample.

    摘要： Embodiments of the present disclosure are directed to a method of making a reaction inhibiting polymer having a formula of M—CO—NR. The method may comprise reacting PAA with an organic coupling reagent and at least one alicyclic amine to produce the reaction inhibiting polymer. In accordance with another embodiment of the present disclosure, a method of making an acryloyl monomer having a formula of Ra—CO—NR may comprise reacting an acrylic acid with an organic coupling reagent and an alicyclic amine to form the acryloyl monomer. Ra may be an alkylene moiety, M may be a poly(acrylic) acid backbone. NR may be an alicyclic amine moiety coupled to the polymer backbone or coupled to the alkylene moiety.
