The BMP powder is prepared by temperature-controlled hydrolysis, staged enzymatic hydrolysis and multiple filtrations. The gardenia fruit oil is prepared by staged enzymatic hydrolysis, multi-step centrifugation, filtration and stratification.

An exhaust treatment apparatus for treating exhaust gas flowing through an exhaust line housing from an upstream location to a downstream location in a downstream direction, the exhaust treatment apparatus comprising a ceramic filter body having a honeycomb structure of a plurality of intersecting porous ceramic walls extending from a first end to a second end in an axial direction and defining a plurality of channels extending in the axial direction, wherein a first transverse face at the first end comprises metal oxide particles affixed to a portion of the intersecting walls. The metal oxide particles may be affixed to the upstream end, or the downstream end, or both the upstream and downstream ends. Preferably the metal oxide particles provide reinforcement to the underlying portion of the walls, and of the honeycomb structure itself.

Air elimination assemblies are described herein. An air elimination assembly for eliminating air from a flow of infusate includes a housing and a hydrophobic filter. The housing defines an infusate flow path having an inlet and an outlet, and an air flow path in fluid communication with the infusate flow path and disposed between the inlet and the outlet of the infusate flow path. The hydrophobic filter is disposed in fluid communication with the air flow path, wherein the hydrophobic filter is configured to permit air from the flow of infusate through a hydrophobic filter media and prevent the flow of infusate through the hydrophobic filter media.

The present invention describes a method which outlines a process for conversion of CBD to a Δ.sup.9-tetrahydrocannabinol (Δ.sup.9-THC) compound or derivative thereof involving treating a naturally produced CBD intermediate compound with an organoaluminum-based Lewis acid catalyst, under conditions effective to produce the Δ.sup.9-tetrahydrocannabinol compound or derivative thereof at a relatively high concentration. The source of the CBD is from industrial hemp having less than 0.3% Δ.sup.9-THC and extracting and purifying a CBD distillate or isolate or a combination thereof. This procedure will produce Δ.sup.9-THC that is essentially free from any other cannabinoids other than some trace amounts of the initial CBD starting material, or about 95% Δ.sup.9-THC and 2-4% CBD. Another aspect of the present invention relates to a process for further purification and enrichment of the Δ.sup.9-THC using distillation and collecting an essentially pure fraction of Δ.sup.9-THC using additional distillation or enrichment form of purification. Included are methods and processes to scale the reaction from the lab to large scale manufacturing. Included are methods for adding a molecule marker to authenticate high purity Δ.sup.9-THC products. Formulations and uses for pharmaceuticals, nutraceuticals, food products, and topicals are also provided.

The present invention provides a handheld smoke filter, the handheld smoke filter includes a housing, wherein one end of the housing is fixedly connected to a smoke spray inlet, the other end of the housing is fixedly connected to a bottom cover, the housing is provided inside with a filter element shell for filtering smoke, the filter element shell is provided with a first sponge layer, an activated carbon filter layer, a second sponge layer and an HEPA filter sequentially disposed from a filter element intake hole to a filter element exhaust hole. The handheld smoke filter of the present invention can use sponge, activated carbon and HEPA for multiple filtrations, so as to collect smoke sprayed from the mouth of a user more effectively, with better filtration effect and better air permeability.

An exhaust gas filter purifies exhaust gas containing particulate matter emitted from an engine. The filter has cell walls and cells surrounded by the cell walls. Through pores formed in the cell walls, adjacent cells are communicated. The cells have open cells opening along an axial direction of the filter, and plugged cells. An upstream end part of the plugged cell is plugged by a plug member. On a cross section perpendicular to the axial direction, a flow-passage sectional area of the plugged cells is larger than a flow-passage sectional area of the open cells. A total length of the filter is not less than a first standard value and is not more than a critical length Lm determined by respective predetermined equations.

A photothermal composition configured to be used in air filter for destroying bioaerosol particles by converting light energy emitted from a light source into heat energy including a photothermal agent is provided. The present invention also concerns an air filter for collecting the bioaerosol particles in an air flow and destroying said bioaerosol particles deposited thereon, including a photothermal agent which converts light energy emitted from a light source into heat energy.

Disclosed herein are ceramic selective membranes and methods of forming the ceramic selective membranes by forming a selective silica ceramic on a porous membrane substrate.

A ceramic filter is provided with a porous substrate 3 “made of ceramic and having partition walls 1 separating and forming a plurality of cells 2 extending from one end face 11 to the other end face 12”, a separation membrane 21 “made of ceramic and disposed on wall surfaces of the cells 2”, and glass seals 31 disposed on the one end face 11 and on the other end face 12 “so as not to cover openings of the cells 2”. Ceramic particles having a thermal expansion coefficient of 90 to 110% of that of glass contained in the glass seals 31 are dispersed in the glass seals 31. There is provided a ceramic filter usable for a long period of time in high temperature conditions.
