“…‐SO 3 H, ‐SO 4 H), as indicated by NH 3 desorption above 300 °C, and weak acid sites (e.g. ‐COOH, phenol) as indicated by lower (40–250 °C) temperature desorption . Through comparison of peak areas obtained from equal weights of each material, results indicate that WH‐PTSA‐220 contains the highest number of moderate to strong acid sites (7.4 % greater peak area above 300 °C) than for WH‐PTSA‐200, followed by other materials in the order WH‐PTSA‐180>WH‐PTSA‐240.…”

“…Temperature‐programmed desorption of ammonia (NH 3 ‐TPD) provides more details on acid behavior, with acid strength in solid acids being related to the desorption temperature. Higher NH 3 ‐desorption temperatures infer stronger acidity, with relative quantities of acid sites being ascertained through integration of NH 3 ‐TPD curve peak area . As seen in Figure C, prepared solid acids contain several types of moderate to strong Brønsted acid sites (e.g.…”

Carbon-based solid acid catalysts were successfully obtained via one-step hydrothermal carbonization (HTC) of water hyacinth (WH) in the presence of p-toluenesulfonic acid (PTSA). Increasing the HTC temperature from 180 to 240 °C resulted in carbonaceous materials with increased sulfur content and less adsorbed water. The material obtained at 220 °C (WH-PTSA-220) contains the highest amount of acid sites and promotes the highest initial rate of two transformations, that is, methanolysis of oleic acid and dehydration of xylose to furfural. While all PSTA-treated WH catalysts gave comparable fatty acid conversions (≈97 %) and furfural yields (≈60 %) after prolonged reaction times, the WH-PTSA-240 system bearing a relatively low acid density maintains the most favorable reusability profile. Higher HTC temperatures (220-240 °C) improved the catalyst reusability profiles due to graphitization and hydrophobicity of the carbon surface. The catalyst systems derived herein from biomass may have potential applications in biorefining platforms, utilizing the conversion of waste biomass to chemicals.

“…Moreover, recent years has witnessed a fast development of sugar catalyst, which was typically prepared through a two-step process. [33][34][35][36] These catalysts were expected to be promising in biomass conversion because they are inexpensive, a source of ample and renewable carbon source as well as good acid density. However, the further development is still a Department of Thermal Science and Energy Engineering, University of Science and Technology of China, Laboratory of Basic Research in Biomass Conversion and Utilization, Hefei 230026, P.

A resorcinol-formaldehyde resin carbon (RFC) catalyst with a well-developed, ordered, mesoporous framework was prepared using a soft template method at room temperature. The carbon was sulfonated in water using sulfanilic acid under mild atmospheric conditions. The sulfonated RFC (S-RFC) was characterized by N 2 adsorption-desorption, elemental analysis, TEM, XPS, and FT-IR. It was determined that S-RFC is an efficient solid acid catalyst for furfural production from xylose and corn stover in gvalerolactone (GVL). The effects of reaction time, reaction temperature, catalyst loading, substrate dosage and water concentration were investigated. 80% furfural yield and 100% xylose conversion were obtained from xylose at 170 C in 15 min with 0.5 g catalyst. Comparatively, 68.6% furfural yield was achieved from corn stover at 200 C in 100 min when using 0.6 g catalyst. Since there was no discernable decrease in furfural yield after multiple conversions utilizing the same catalyst, the recyclability of the catalyst is considered good.

A carbonaceous solid acid catalyst obtained from by‐products of sorbitol dehydration process, was prepared via facile one‐step carbonization and sulfonation method. The results of various characterization technologies showed that as‐prepared acidic carbon bearing ‐SO3H, ‐COOH and ‐OH groups with Brønsted acid sites was effective for solvent‐free dehydration of sorbitol to produce isosorbide. Full complete sorbitol conversion with 72.1% isosorbide yield was achieved at 170 °C after 2 h reaction. Catalyst could be used for three cycles retaining the most of its initial catalytic activity. Importantly, the catalyst and reaction by‐products in this process could be easily recycled and facilely utilized, offering sustainable process in production of isosorbide from sorbitol.
