The invention discloses a method for producing bio-fuel (BF) from a high-viscosity biomass using thermo-chemical conversion of the biomass in a production line (10) with pumping means (PM), heating means (HM) and cooling means (CM). The method has the steps of 1) operating the pumping means, the heating means and the cooling means so that the production line is under supercritical fluid conditions (SCF) to induce biomass conversion in a conversion zone (CZ) within the production line, and 2) operating the pumping means so that at least part of the production line is in an oscillatory flow (OF) mode. The invention is advantageous for providing an improved method for producing biofuel from a high-viscosity biomass. This is performed by an advantageous combination of two operating modes: supercritical fluid (SCF) conditions and oscillatory flow (OF).

Methods of producing a CBD/THC oil are disclosed. In some embodiments, the method may include extracting CBD/THC from plant matter using one or more solvents, winterizing the solvent extract, and evaporating the one or more solvents from the winterized extract. The method may additionally include distilling the evaporated extract via a short path distillation apparatus to produce an initial distillate oil, mixing the initial distillate oil with at least one solvent, and running the mixture of initial distillate oil and at least one solvent through a chromatography column to produce an effluent. The method may further include evaporating the at least one solvent from the effluent, distilling the evaporated effluent via a short path distillation apparatus to produce a final distillate oil, and mixing one or more desired terpenes with the final distillate oil.

A method for producing bisphenol A (BPA) is provided. The method includes step A of degrading a polycarbonate resin in a solvent and distilling off the solvent to obtain a crude solution A; step B of subjecting acetone and phenol to dehydration condensation; step C of distilling off unreacted acetone and water to obtain a concentrated liquid C; step D of crystallizing the concentrated liquid C to obtain a slurry liquid, from which a mother liquor D is obtained; step H of obtaining a solution H1 or a solution H2 from the crude solution A and part of the mother liquor D; and step I of supplying the solution H1 or H2 to the step B or C. The solution H1 contains BPA obtained by degrading BPA contained in the crude solution A and the mother liquor D into phenol and isopropenylphenol and then rebonding phenol and isopropenylphenol, and the solution H2 contains phenol obtained by degrading BPA contained in the crude solution A and the mother liquor D into phenol and acetone.

Some variations provide a process of converting a cannabinoid into a purified cannabinoid derivative, comprising: providing a starting composition comprising a cannabinoid; providing a C.sub.9-C.sub.11 non-aromatic hydrocarbon solvent; introducing the starting composition and the solvent to a conversion reactor; chemically converting some, but not all, of the cannabinoid to a cannabinoid derivative, generating a reaction mixture containing unreacted cannabinoid; conveying the reaction mixture to a crystallization unit; cooling the reaction mixture to precipitate unreacted cannabinoid out of the reaction mixture, thereby generating a mother liquor containing the cannabinoid derivative; and isolating and recovering the cannabinoid derivative from the mother liquor. Systems configured to carry out the disclosed processes are also provided. This invention offers a large-scale solution to economically convert CBD to D9-THC, among many other example. The principles of the invention may be applied to the conversion of various cannabinoids and terpenes into derivative products.

The present disclosure relates to the preparation of a highly pure cannabidiol compound by a novel synthesis route. The cannabidiol compound can be prepared by an acid-catalyzed reaction of a di-halo olivetol with menthadienol, followed by two crystallization steps. The highly pure cannabidiol compound is produced in high yield, stereospecificity, or both, and shows exceedingly low levels of Δ-9-tetrahydrocannabinol at the time of preparation and after storage.
