The invention is directed to manufacture of fertilizer having commercial levels of nitrogen supplemented with organic substances. The process treats organic matter with acid causing hydrolysis of organic polymers after which the mix is injected with nitrogen. The resultant sterilized and liquefied organic matter is disbursed over recycled material for the production of granules. Because the process allows for the controlled addition of acids and ammonia, desired levels of components can be achieved. The process is scalable, odor controlled and safe thereby allowing for the location of biosolid processing facilities in most any location. Further, the fertilizer of the invention provides a dual nitrogen-release profile when applied to crops. After application to soil, fertilizer of the invention releases an immediate bolus of nitrogen, similar to traditional ammonium sulfate, followed by continued slow release of nitrogen typically over a season.

A method of producing phenol and acetone can comprise: alkylating benzene with a C.sub.2-6 alkyl source in the presence of a zeolite catalyst to produce a C.sub.8-12 alkylbenzene; oxidizing the C.sub.8-12 alkylbenzene in the presence of an oxygen containing gas to produce a C.sub.8-12 alkylbenzene hydroperoxide; cleaving decomposing the C.sub.8-12 alkylbenzene hydroperoxide in the presence of an acid catalyst to produce phenol, a C.sub.3-6 ketone, and undesirable side products such as, but not limited to acetaldehyde, DMBA, acetophenel one, AMS, AMS dimers, unidentified heavies, or a combination comprising at least one of the foregoing; and monitoring a concentration of the C.sub.8-12 alkylbenzene hydroperoxide in a process stream of a reactor in real time at a temperature and a pressure of the process stream; and in real time, controlling a parameter of the reactor and/or the cleaving decomposing in response to the concentration of the C.sub.8-12 alkylbenzene hydroperoxide.

A system for continuously treating recycled polymeric material includes a hopper configured to feed the recycled polymeric material into the system. An extruder can turn the recycled polymeric material in a molten material. In some embodiments, the extruder uses thermal fluids, electric heaters, and/or a separate heater. The molten material is depolymerized in a reactor. In some embodiments, a catalyst is used to aid in depolymerizing the material. In certain embodiments, the catalyst is contained in a permeable container. The depolymerized molten material can then be cooled via a heat exchanger. In some embodiments, multiple reactors are used. In certain embodiments, these reactors are connected in series. In some embodiments, the reactor(s) contain removable static mixer(s) and/or removable annular inserts.

A process for preparation of a polymer product comprising the steps of i) feeding an aqueous mixture comprising a monoethylenically unsaturated monomer or a mixture of monoethylenically unsaturated monomers into a first reactor device (2) through at least one inlet; ii) partially polymerizing the monomer or monomers and transferring the polymerizing monomer or mixture of monomers from the inlet to an outlet (3) of the first reactor device (2) to provide a partially polymerized product; iii) flowing the partially polymerized product out of the outlet (3), in which no more than 60% of the monomer or mixture of monomers has been polymerized in the partially polymerized product as it exits the outlet (3) of first reactor device (2), and transferring it to a further reactor device (5), in which the further reactor device (5) has an inlet and an outlet (6);
iv) continuing the polymerization in the further reactor device (5) and removing the polymer product from the outlet (6) of the further reactor device (5),
characterized in that the first reactor device (2) comprises a positive displacement pump.

The invention relates to a process for preparation of at least one of methacrylic acid and a methacrylic acid ester, comprising the process stepsgas phase oxidation of at least one C.sub.4 compound, quenching of the reaction phase, separation and purification of the obtained methacrylic acid and optionally esterification, wherein the C.sub.4 compound is a methacrolein comprising mixture, originating from at least two different methacrolein sources, a first methacrolein source being a feed stream obtained by the heterogeneously catalyzed gas phase oxidation of isobutylene or tert-butyl alcohol or isobutylaldehyde or a mixture of two or more thereof, a second methacrolein source being a feed stream obtained by the reaction of propionaldehyde with a C.sub.1 extending agent, preferably formaldehyde, and where said methacrolein can be obtained either completely from the first methacrolein source, or completely from the second methacrolein source or from any mixture of both.
