Abstract: This invention provides a method for reclaiming oil from waste plastic in such a way that thermosetting resins and solid foreign matter in the plastic will not pose a problem. This method greatly reduces the burden of presorting the garbage or industrial waste. To achieve this objective when oil is to be reclaimed from a waste plastic containing chlorine compounds, such as vinyl chloride, the plastic must first be stripped of chlorine. Prior to pyrolysis, while being conveyed forward in a continuous stream, the plastic is mixed with heated sand and/or an additive agent to raise its temperature to 250-350° C. This creates a product which is comprised of a mixture of sand and substantially dechlorinated plastic. The product is mixed with heated sand to heat it directly to a temperature of 350-500° C. It is maintained at this temperature until pyrolysis occurs.

Abstract: A high-yield process for converting lignin into reformulated, partially oxygenated gasoline compositions of high quality is provided. The process is a two-stage catalytic reaction process that produces a reformulated, partially oxygenated gasoline product with a controlled amount of aromatics. In the first stage of the process, a lignin feed material is subjected to a base-catalyzed depolymerization reaction, followed by a selective hydrocracking reaction which utilizes a superacid catalyst to produce a high oxygen-content depolymerized lignin product mainly composed of alkylated phenols, alkylated alkoxyphenols, and alkylbenzenes.

Abstract: The amount of limonene produced during pyrolysis of scrap tire carcass or polyisoprene rubber can be increased by decreasing residence time of the isoprene gas produced during the thermal degradation of polyisoprene rubber in the high temperature reactor region of an oven. This is achieved by using a novel oven design which permits rapid expansion of the isoprene gas away from the high temperature reactor region of the oven to a cooler region where the gas forms limonene and condenses. This pyrolysis method also decreases the amount of soot produced while increasing the amount of limonene produced. Furthermore, this system readily enables separation of the solid, liquid and gas phases produced during pyrolysis.

Abstract: This process relates to reforming a full-boiling range hydrocarbon feed in two parallel stages while maximizing the catalyst life of the heavy cut reformer and/or reducing the complexity of the plant by preferentially sending the higher purity Aromax.RTM. hydrogen to the heavy cut reformer.

Abstract: An arrangement for the controlled production of an essentially linear array of hydrocarbon feed injection jets reduces required clearances and elevation while facilitating modification of the contacting locating a feed distributor containing a linear array of jets at a standpipe junction point to provide choke point for particle flow control. The flow properties of the extended particle layer are controlled by adjusting the density of the particles above the choke point created by the upper part of the standpipe inside diameter and the top of the distributor. Steam or another fluidization medium may be added to the particles directly above the distributor for this purpose. This invention can also modify the particle or feed injection characteristics by changing the projection of the distributor into the standpipe to adjust the flow area over the choke point and by the use of bottom slides or baffles to change the flow area size and configuration.

Abstract: A highly dispersed iron-based ionic liquid or liquid-gel catalyst which may be anion-modified and metals-promoted has high catalytic activity, and is useful for hydrocracking/hydrogenation reactions for carbonaceous feed materials. The catalyst is produced by aqueous precipitation from saturated iron salt solutions such as ferric sulfate and ferric alum, and may be modified during preparation with anionic sulfate (SO.sub.4.sup.2-) and promoted with small percentages of at least one active metal such as cobalt, molybdenum, palladium, platinum, nickel, or tungsten or mixtures thereof. The resulting catalyst may be used in a preferred ionic liquid form or in a liquid-gel form, and either fluidic form can be easily mixed and reacted with carbonaceous feed materials such as coal, heavy petroleum fractions, mixed plastic waste, or mixtures thereof.

Abstract: A method and apparatus are disclosed for removing water from a recycle gas stream in a catalyst regeneration process. A recycle gas stream contacts catalyst and the catalyst sorbs water from the recycle gas. Some of the now-dried recycle gas recirculates to the regeneration process, thereby decreasing the water content in the regeneration process. The catalyst containing sorbed water passes to a desorption zone, where water is desorbed from the catalyst and the desorbed water is rejected from the process. This method and apparatus are useful for extending the life of catalyst in catalytic hydrocarbon processes that employ continuous or semi-continuos catalyst regeneration zones.
