摘要： Methods of controlling olefin polymerization reactor systems may include a) selecting n input variables, each input variable corresponding to a process condition for an olefin polymerization process; b) identifying m response variables corresponding to a measurable polymer property; c) adjusting one of more of the n input variables using the olefin polymerization reactor system and measuring each of the m response variables as a function of the input variables for olefin polymers; d) analyzing the change in each of the response variables as a function of the input variables to determine coefficients; e) calculating a Response Surface Model (RSM) for each response variable determined in step d); f) applying n selected input variables to the calculated RSM to predict one or more of m target response variables; and g) using the n selected input variables to operate the olefin polymerization reactor system and provide a polyolefin product.

摘要： A pyrolysis oil fractionation system for treating a pyrolysis oil feed includes a fractionation column, at least one treatment catalyst bed, and a plurality of distillation trays. The system further includes a condenser to receive a light fraction and produce a condensed gasoline product and a vapor, a receiver coupled to the condenser, a knockout drum, and a distillate stripper coupled to the fractionation column. A method for treating a pyrolysis oil feed includes, in a fractionating column, dehydrohalogenating, decontaminating, and/or dehydrating a pyrolysis oil feed in at least one treatment catalyst bed, and distilling the treated pyrolysis oil feed into a light fraction, a middle fraction, a heavy fraction, and a bottom fraction. The method further includes condensing the light fraction and producing a condensed gasoline product and a vapor, separating a fuel gas product from the vapor, and stripping the middle fraction to produce a distillate product.

摘要： This disclosure relates to the production of chemicals and plastics using pyrolysis oil from the pyrolysis of plastic waste as a co-feedstock along with a petroleum-based, fossil fuel-based, or bio-based feedstock. In an aspect, the polymers and chemicals produced according to this disclosure can be certified under International Sustainability and Carbon Certification (ISCC) provisions as circular polymers and chemicals at any point along complex chemical reaction pathways. The use of a mass balance approach which attributes the pounds of pyrolyzed plastic products derived from pyrolysis oil to any output stream of a given unit has been developed, which permits ISCC certification agency approval.

摘要： Techniques are provided for catalyst preparation. A method includes heating a mixture of one or more transition metal compounds and an oxide support or a chromium containing oxide support to a temperature or a set of temperatures that enables the a transition metal compound of the one or more transition metal compounds to sublime, melt, or thermally decompose, such that a transition metal of the one or more transition metal compounds reacts with and is deposited onto a surface of the oxide support or the chromium containing oxide support to form a catalyst, and activating the catalyst. The catalyst is configured to facilitate a reaction that produces a target inorganic material.

摘要： Processes for producing ethylene-based polymers and oligomers from ethanol include the steps of contacting the ethanol and a catalyst to produce a reaction mixture containing ethylene, wherein a first portion of the ethanol is derived from a biomass and a second portion of the ethanol is derived from a plastic, a mixed solid waste stream, or a combination thereof, separating at least a portion of the ethylene from the reaction mixture, and contacting ethylene with a suitable polymerization or oligomerization catalyst composition to produce the ethylene polymer or ethylene oligomers. A related process for producing ethylene-based polymers and oligomers uses a first ethylene feed derived from ethanol and a second ethylene feed derived from a plastic, a mixed solid waste stream, or a combination thereof.
