Psoriasis is a chronic, immune-mediated inflammatory skin disease. The Goeckerman regimen, formulated for the treatment of psoriasis, consists of exposure to ultraviolet B (UVB) light and application of crude coal tar (CCT). The following protocol is for the administration of Goeckerman therapy for the treatment of moderate-to-severe psoriasis.

Here, we present a protocol to synthesize nitrogen/oxygen dual-doped mesoporous carbon from biomass by chemical activation in different pyrolysis modes followed by modification. We demonstrate that the microwave pyrolysis benefits the subsequent modification process to simultaneously introduce more nitrogen and oxygen functional groups on the carbon.

Experimental methods for fast pyrolysis of lignocellulosic biomass to produce bio-oils and for the catalytic hydrotreating of bio-oils to produce fuel range hydrocarbons are presented. Hot-vapor filtration during fast pyrolysis to remove fine char particles and inorganic contaminants from bio-oil was also assessed.
FAQs
Temperature, heating rate, and residence time act as the principal controllable variables in pyrolysis treatment. Temperature supplies the energy needed to break chemical bonds, while heating rate and the time material remains exposed to heat influence how extensively conversion proceeds. Because these variables alter the proportions of char, condensable liquids, and noncondensable gases, researchers adjust them according to the desired product distribution.
The three product fractions represent different chemical and physical outcomes. Solid char is a carbon-rich material, condensable liquids form a recoverable liquid fraction, and noncondensable gases remain gaseous under the process conditions. Tracking how much of each fraction forms lets chemists evaluate conversion performance and select conditions for fuels, adsorbents, or other carbon-based products.
The process can be applied to biomass, polymers, and waste, so feedstock selection connects pyrolysis treatment to different chemical and practical goals. Examining the starting organic material alongside the resulting fractions helps researchers study changes in composition and physical form, as well as the reaction pathways responsible for conversion, rather than treating all inputs as equivalent.
A practical workflow begins by selecting an organic feedstock and placing it under controlled heating with oxygen absent or nearly absent. Researchers then vary or record temperature, heating rate, and residence time, followed by examination of the solid char, condensable liquids, and noncondensable gases. This workflow connects operating conditions with product yield and the resulting material properties.
Pyrolysis treatment is useful when researchers want to reduce waste or convert biomass into more valuable chemical and physical forms. Depending on the selected conditions, the process can support production of solid char, condensable liquids, and noncondensable gases. These outputs provide a basis for studying fuels, adsorbents, carbon-rich materials, energy recovery, and environmental performance.
Chemical analysis uses the changes between an original feedstock and its products to investigate how heating transforms organic matter. Researchers can compare composition and physical form before and after treatment, then relate those changes to the formation of char, liquids, and gases. This approach helps clarify reaction pathways and supports optimization of product yield and energy recovery.
