Abstract: A novel method is developed to remove wax and terpene from the wild hemp plants to produce enriched cannabidiol (CBD) crude oil with high quality and further purify the crude oil into crystal/isolate with 99.0% content of CBD. The method utilizes titanium dioxide (TiO2) photocatalyst for redox reaction under the irradiation of UV (ultraviolet) light in a solvent extraction process of CBD, which significantly removes accompanying wax and terpene. With the beneficial photocatalyst property, the TiO2 decomposes the wax and terpene in the wild hemp crude extract through appropriate UV radiation to induce catalytic reaction at specific PH (potential hydrogen) levels. Through optimizing the photocatalyst dewaxing using TiO2, the method achieves the best dewaxing effect and maximum terpene reduction. Thus, the method offers a low-cost, reusable, and biologically friendly process of removing wax and terpene to maximize the efficiency and effectiveness of the separation processes in the CBD production.

Abstract: A traveling hydraulic handling machine of energy-saving type includes a driving system and a control system for both hoisting and traveling. The hydraulic handling machine converts partly potential energy of a heavy object before being lowered and kinetic energy of a vehicle before being braked to pressure energy of a fluid and stores the pressure energy into a hydraulic energy accumulator (15) by using added hydraulic elements with the aid of the original hydraulic system of the handling machine during lifting and lowering of the heavy object as well as braking and starting of the vehicle, thus enabling potential energy of the heavy object and kinetic energy of the vehicle obtained by consuming power to be partly regenerated during next lifting of the heavy object and starting of the vehicle, to reduce the load and power of a power machine for driving an oil pump and starting the vehicle.
