catalytic fast pyrolysis of wastewater sludge was conducted to assess pyrolysis temperature and atm., and catalysts effect on C and N distribution in a fixed-bed reactor. a H2 atmosphere had the lowest C selectivity of solid products and the highest gaseous product yield over HZSM-5 (HZ) at the same temperature vs. Ar and steam atmospheres. higher temperature led to increased C selectivity of gaseous products and decreased C selectivity of solids. H2 increased the C yield of light aromatics (LA); steam reduced generation of LA. over 0.5 Ni-HZ, H2 had the highest LA C yield (11.4%) vs. 1.6% from non-catalytic fast pyrolysis of sludge. higher temperatures, H2 and steam atmospheres, and metal-loaded HZ promoted N transfer to gaseous products. the highest N yield (i.e., NH3) of 55.6% was obtained from sludge pyrolysis over HZ at 700° in a H2 atmosphere. In the experiment, the researchers used many compounds, for example, 2-Isopropylpyridine (cas: 644-98-4Recommanded Product: 2-Isopropylpyridine).
2-Isopropylpyridine (cas: 644-98-4) belongs to pyridine derivatives. In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. Pyridine groups exist in countless molecules, and their applications include catalysis, drug design, molecular recognition, and natural product synthesis.Recommanded Product: 2-Isopropylpyridine
