Catalytic pyrolysis of crude glycerol over a shaped H-ZSM-5 zeolite catalyst with (partial) recycling of the product oil was studied with the incentive to improve benzene, toluene, and xylene (BTX) yields. Recycling of the polycyclic aromatic hydrocarbon (PAH) fraction, after separation from BTX by distillation …

A process for the prepn. of arom. compds. from a feed stream contg. biomass or mixts. of biomass, the process comprising: a) subjecting a feed stream contg. biomass or mixts. of biomass to a process to afford a conversion product comprising arom. compds.; b) recovering the arom. compds. from said conversion …

tmoA and related genes encode the alpha-subunit of the hydroxylase component of the major group (subgroup 1 of subfamily 2) of bacterial multicomponent mono-oxygenase enzyme complexes involved in aerobic benzene, toluene, ethylbenzene and xylene (BTEX) degradation. A PCR-denaturing gradient gel electrophoresis …
