Abstract
Processes and a catalyst for the cycloaddition of an olefin, such as C2 to C4 olefins like, ethylene, propylene and butylene, to a biomass derived compound, such as dimethylfuran, furan, methylfuran. The catalyst has a relatively low silica to alumina ratio of around 25 compared with conventional catalysts which have a ratio greater than 1000. The catalyst has phosphorus and may be a beta zeolite. Such a catalyst can be used to generate a high yield of bio-based para-xylene.
